Food processing is a multi-trillion dollar industry that encompasses facilities such as bakeries, meat and poultry plants, bottling lines, dairies, canneries and breweries. For all of these food processing plants a commercial flooring system is essential for maintaining a hygienic environment. Few areas of a plant provide as much opportunity for the spread of bacteria, mold, fungi and dust as the floor. Hazardous materials from a contaminated floor can easily be spread from worker’s shoes and mobile equipment. Food processing plants present a unique set of challenges that require careful consideration of floor properties and installation.
Food processing plants floors are subjected to constant, high concentrations of salt, alkaline and oil compounds that substantially degrade the floor and thereby risk food contamination and facility shutdown. These compounds can come from common food production by-products like oils, fats, dairy products, sugar solutions, blood, and natural acids or from harsh cleaners and disinfectants. Even with frequent and thorough cleaning these substances can—and will—result in microbial growth and the spread of bacteria in untreated concrete or poorly installed resinous flooring.
Cleaning floors is an essential part of maintaining food processing operations to keep up with government standards. A proper floor coating is a necessity for dealing with the vigorous, harsh cleaning procedures that typically include very hot water and aggressive cleaning chemicals. Depending on the exposure to corrosive, temperature and moisture conditions a thin film coating may suffice; however, in most cases, a thick, durable floor coating is needed to endure the cleaning operations. If too thin of a coating is used the repeated barrage of high pressure, high-temperature hot water and steam will strip the floor coating. Only an experienced flooring professional can determine the proper floor coating for a facility.
In addition to the properties of the floor coating, proper installation is essential for maintaining a hygienic, safe facility. If a floor is not seamless even the best floor coatings are vulnerable to germ buildup within gaps and cracks. To prevent harmful substance accumulation, a seamless coving transition from the floor to the wall is needed. Not only does that make the floors unsanitary, but it also can spread to other parts of the facility, equipment and product. Coving also aids in the cleaning process by allowing for hosing around the sides and corners of the room where germ buildup is most common.
An often-overlooked—yet critical—aspect of floor installation is having the proper pitch to promote water drainage. Having pools of water is not only dangerous for workers but for product safety. Such an examples of this issue is the Listeria outbreak at cantaloupe producer Jensen Farms, which led to 33 fatalities, 143 hospitalized victims, and ultimately, the end of their business. In the 2011 FDA released a report that focused on “Factors Potentially Contributing to the Contamination of Fresh, Whole Cantaloupe Implicated in the Multi-State Listeria monocytogenes Foodborne Illness Outbreak”. The conclusion was reached that the leading cause of Listeria spreading was due to a poorly constructed packing facility floor that was difficult to clean and allowed water to pool. The best way to prevent a similar situation at your plant is to make sure you get an experienced flooring expert, who understands your facility’s needs, to choose a floor with the right properties and to properly install it.
In a Q&A with Food Safety Tech, Eddie Hall, business development director and food safety expert at Vital Vio looks ahead to 2020 and how technology will be impacting food safety, the additional measures that the industry will be taking to protect consumers, and the critical emphasis on sanitation.
Food Safety Tech: What are some of the touch points for food safety innovation in the supply chain in 2020?
Eddie Hall: When we think of the supply chain, we often imagine food traveling during transportation—by road, rail and air. During transit, our food comes into contact with countless surfaces, hands, tools and bacteria that travels from the farm to the table. However, transit isn’t the only place for germ spread and bacteria growth. When food reaches the factory for processing and packaging, there are opportunities for contact with debris, mold and dust, along with un-sanitized machinery and employees. Not only does this negatively affect the health of our workers, but also the cleanliness and safety of the food that consumers are buying off the shelves. In food manufacturing plants, Zones 1 and 2 are the most obvious for safety innovation in the supply chain, given food is bound to come into contact with tools, conveyor belts, etc. However, processors must consider the touch points in Zones 3 and 4 as well—such as employee break rooms, bathrooms and offices around the plant that foster bacteria. If these areas are not cleaned, food manufacturers have a significantly higher chance of breeding bacteria in food production areas, even if the right protocols are put in place in those zones.
FST: How will the retail sector step up to the consumer demand for safer food?
Hall: Consumers are increasingly demanding transparency around how food ends up on their plate, and prioritizing purchasing from brands that they trust to be safe. Food suppliers are being careful to remove harmful chemicals from the manufacturing process, along with displaying ingredients and supply chain information. For example, Bumble Bee Foods is using blockchain technology for its tuna fish, allowing consumers to access detailed information around the tuna’s origin, authenticity, freshness and sustainability by scanning the QR code on its packaging. Panera Bread has been consistent in offering customers ingredient transparency [by] providing calorie counts on menu items and removing antibiotic-treated animal proteins, as well as vocalizing recent efforts to perform safety audits throughout its supply chain. Not only does tracking technology and clarity meet consumers’ demands, but [it] also helps retailers pinpoint locations of outbreaks, foodborne illness and mislabeling. We’re already seeing retailers step up to meet the growing demand for safer food, but in 2020 we will see an uptick in brand transparency around supply chain information, safety programs and ingredient clarity within restaurants, fast food chains, processing companies and grocery stores.
FST: How will automation play a role in advancing food safety?
Hall: Food processing companies and retailers are implementing remote monitoring technologies that track data and help measure protocol, temperature controls, sanitation, record-keeping and food traceability. Automation can also help advance food safety through methods such as enhance sanitation and sterilization efforts. It is critical for food industry employees to maintain clean environments, but continuously cleaning every hour of every day can become labor-intensive, and sometimes fall off the to-do list. Automated technologies can take on some of these tedious tasks and work in our favor to heighten food safety. For example, Stop and Shop’s new robot, Marty, patrols the aisles to detect food on the floor, torn packaging, empty shelves and more. However, robots aren’t the only place we’re seeing automation in action. Vital Vio has found a way to automate killing bacteria through antimicrobial LED lighting technology, which continuously kills pathogens with the flick of a switch. Automated tech isn’t meant to replace workers, but to enhance their work around cleaning, sanitizing and meeting safety requirements. In 2020, automation is expected to explode and it’s important for leaders in the food and beverage industry to take advantage of safety tech innovations to advance food safety in 2020 and beyond.
FST: How will food companies continue to work towards reducing contamination issues and recalls?
Hall: The U.S. government has stepped in to tackle issues in the food industry by implementing new regulations, such as FSMA. This regulation urges food companies to shift from reactively responding to safety and contamination issues, to proactively working to prevent them. In an effort to reduce recalls, retail giant Walmart recently employed blockchain to track its lettuce supply chains all the way back to the grower. For food companies to reduce contamination, they must also implement more automated sanitation technologies along the supply chain. The most common food contaminants are usually invisible to the naked eye, such as mold, Listeria, Salmonella and E. coli. Sanitation automation tech—such as antimicrobial LED lighting—can continuously kill microscopic bacteria and prevent regrowth, ensuring clean food and equipment. Not only will food companies begin implementing more sanitization technologies, but also focus on other ways, like blockchain traceability, to prevent food recalls and bacteria growth that pose serious health risks to their customers.
FST: Any additional comments?
Hall: Our Dirty Truth report reveals disturbing stats around Americans’ cleaning habits, such as 1 in 4 (27%) do not sanitize their hands after traveling on public transportation. This means that factory or grocery employees that commute to work via bus, train, etc. are bringing bacteria and other germs with them. What’s worse, 1 in 6 Americans get sick and 3,000 die each year from consuming contaminated foods or beverages. This alarming rate can only be improved if we see effort from all sides of the industry—including food processors, manufacturers, workers throughout the supply chain and retailers. Continuous cleaning and sanitation measures can be labor-intensive and sometimes impossible to tackle throughout the day. Luckily, automated technology exists and is expected to address this growing issue of contamination, the spread of bacteria, recalls, and consumer demand for safety and transparency.
In the complex food supply chain, a single product travels a long journey before reaching consumers’ plates. It’s no wonder that it has become so difficult to control the quality and safety of food. As food moves from trucks to conveyor belts and through grocery store shelves and shopping carts, the risk for harmful bacteria to contaminate products rises immensely. What’s worse is pinpointing the source of contamination can be nearly impossible, leaving food manufacturers scrambling to “fix” the error without even knowing the cause.
In recent recalls, processing plants completely shut down operations in an effort to resolve the issue and thoroughly sanitize their entire facilities. While this is good news for consumers, this type of reactive response will undoubtedly have a long-term, irreversible impact on the business—both financially and potentially for the brand’s reputation. Consumers remember the name of the company they heard on the evening news that had to pull thousands of pounds of products from shelves in their city or region. Then, when they make their weekly trip to the grocery store, they likely make sure to avoid that company’s products in fear of potential quality issues that could make them and their families sick. It’s a deadly cycle for consumers and public health, as well as business livelihood.
Product and consumer safety must continue to be the top priority for the food industry. The success of these companies literally depends on it. With so much on the line, the food industry must come together to spark a shift in how they operate to prevent food recalls rather than having to respond to them.
Stopping Recalls to Save Lives and Businesses
To move in the direction of mitigating pathogens from ever coming into contact with food and therefore preventing recalls altogether, processors must develop and deploy new strategies that keep facilities consistently clean. The U.S. government is stepping in with regulations such as FSMA that urge companies to shift from reactively responding to safety issues, to proactively working to prevent them. This is the fundamental shift that is needed across the food supply chain in order to protect consumers and food producing businesses.
Important new technologies have emerged in recent years that can add new layers of meaningful protection to continuously combat contamination across the supply chain. When coupled with existing disinfection and cleaning practices, these new technologies can help mitigate the introduction of harmful pathogens as food moves from point A to point B, with all the stops made in between.
One example is the advent of a new class of technology that incorporates antimicrobial LED lighting, which enables food processors to take an “always on” approach to keeping surfaces free of harmful pathogens. Since these lights meet international standards for unrestricted and continuous use around people, they’re able to irradiate large places and the smallest of spaces, all while workers are present.
However, simply deploying these new technologies isn’t enough. For new prevention strategies to be truly successful, food processors should consider the bigger picture. A large percentage of food processors focus primarily on bolstering their sanitation approaches in the areas that have the highest likelihood of coming into contact with food products. This is logical, as Zone 1 and Zone 2 are typically the highest risk for contracting and spreading harmful pathogens.
However, processors are leaving holes in their sanitation strategies by not taking measures to keep areas, such as Zone 3 and Zone 4, also well protected. To ensure food remains free of contaminants, plant managers must ensure the entire environment is fully protected, including the belts and vessels that the food touches, as well as the break rooms where employees rest and offices where management holds meetings. If these areas aren’t kept equally as clean, facilities are risking outside contaminants to enter Zone 1 that can ultimately compromise their food products.
Food recalls have become eerily common, putting a strain on public health and businesses. To stop what seems to be rising to crisis level, all companies involved in the food supply chain need to take a proactive stance toward prevention. This means deploying advanced technologies that continuously prevent harmful pathogens from taking root anywhere in their facilities. Simple yet thoughtful solutions, such as antimicrobial LED lighting, ensure food companies are one step closer to keeping all of us and their businesses safe.
The following infographic is a snapshot of the hazard trends in milk and dairy from Q3 2019. The information has been pulled from the HorizonScan quarterly report, which summarizes recent global adulteration trends using data gathered from more than 120 reliable sources worldwide. For the past several weeks, Food Safety Tech has provided readers with hazard trends from various food categories included in this report. Next week will conclude this series.
There’s a reason you can eat or drink pretty much anything you want from American grocery stores and not get sick. Food manufacturing is highly regulated and subject to rigorous quality control.
Before food and beverages hit store shelves, the manufacturer must have a Hazard Analysis Critical Control Point (HACCP) system in place. The HACCP system requires that potential hazards—biological, chemical and physical— be identified and controlled at specific points in the manufacturing process. In addition, fresh foods undergo a kill-step. This is the point in the manufacturing or packaging process where food is treated to minimize and remove deadly pathogens like bacteria, mold, fungus and E. coli.
Generally speaking, when cannabis hits dispensary shelves, a less stringent set of rules apply, despite the fact that cannabis is ingested, inhaled and used as medicine. Cultivators are required to test every batch, but each state differs in what is required for mandated testing. Compared to the way food is regulated, the cannabis industry still has a long way to go when it comes to consumer safety—and that poses a considerable public health risk. In the early stages of legalization, the handful of legal states did not have rigid cannabis testing measures in place, which led to inconsistent safety standards across the country. State governments have had a reactionary approach to updating testing guidelines, by and large implementing stricter standards in response to product recalls and customer safety complaints. While local regulators have had the best intentions in prioritizing consumer safety, it is still difficult to align uniform cannabis testing standards with existing food safety standards while cannabis is a Schedule I substance.
The stark differences in safety measures and quality controls were first obvious to me when I moved from the food and beverage industry into the cannabis industry. For five years, I operated an organic, cold-pressed juice company and a natural beverage distribution company and had to adhere to very strict HACCP guidelines. When a friend asked me for advice on how to get rid of mold on cannabis flower, a light bulb went off: Why was there no kill step in cannabis? And what other food safety procedures were not being followed?
What to know more about all things quality, regulatory and compliance in the cannabis industry? Check out Cannabis Industry Journal and sign up for the weekly newsletterThe current patchwork of regulations and lack of food safety standards could have dire effects. It not only puts consumer health in jeopardy, but without healthy crops, growers, dispensaries and the entire cannabis supply chain can suffer. When a batch of cannabis fails microbial testing, it cannot be sold as raw flower unless it goes through an approved process to eliminate the contamination. This has severe impacts on everyone, starting with the cultivator. There are delays in harvesting and delivery, and sometimes producers are forced to extract their flower into concentrates, which really cuts into profits. And in the worst cases, entire crop harvests may have to be destroyed.
So, what do cannabis cultivators and manufacturers have to fear the most? Mold. Out of all the pathogens, mold is the most problematic for cannabis crops, perhaps because it is so resilient. Mold can withstand extreme heat, leaving many decontamination treatments ineffective. And most importantly, mold can proliferate and continue to grow. This is commonplace when the cannabis is stored for any length of time. Inhaling mold spores can have serious adverse health effects, including respiratory illness, and can even be deadly for immunocompromised consumers using it for medical reasons.
What the industry needs is a true kill step. It’s the only way to kill mold spores and other pathogens to ensure that they will not continue to grow while being stored. States that mandate microbial testing will benefit from the kill step because more cultivators will be in compliance earlier in the process. In states that don’t require comprehensive microbial testing, like Washington and Oregon, the kill step is a critical way to provide consumers with a preemptive layer of protection. Microbial testing and preventative decontamination measures encourage customer brand loyalty and prevents negative press coverage.
Adopting a HACCP system would also build additional safeguards into the system. These procedures provide businesses with a step-by-step system that controls food safety, from ingredients right through to production, storage and distribution, to sale of the product and service for the final consumer. The process of creating HACCP-based procedures provides a roadmap for food safety management that ultimately aligns your staff around the goal of keeping consumers safe.
It’s high time for the cannabis industry to adopt FDA-like standards and proactively promote safety measures. Cannabis growers must implement these quality controls to ensure that their products are as safe to consume as any other food or drink on the market. Let’s be proactive and show our consumers that we are serious about their safety.
Various types of pest birds can impact food plant structures and facility surroundings. Even a single bird that finds its way into a food plant can trigger a host of concerns such as, failed audits, product contamination, plant closure, production stoppage, lost revenues, fines, structural damage, health hazards to occupants and fire hazards.
In most cases, a food plant operation has a bulletproof pest control plan; however, in most cases, birds are always an afterthought in most pest management plans. After inspecting and consulting numerous food plants, I hear the same story over and over: “I have a person in the warehouse that can chase them out” or, “are birds really a big deal?” or, “why do I have to be concerned about birds?” and on and on. Despite what you may think, birds are a big deal, and you should take them seriously!
Since food processing plants contain areas that have very sensitive environments, birds can introduce various adulterants and harmful contaminants. Birds can cause potential harm to humans due to foodborne illness.
Pest Bird Species
There are four main pest birds: Pigeon, Starling, Sparrow and Seagull. Each one of these birds can cause a host of concerns and issues for food processing facilities. Just one bird can cause catastrophic damage. In most cases, small pest birds such as Sparrows and Starlings can gain access into a facility through a variety of ways:
Damaged bumpers around truck bay loading dock doors.
Open doors (seems obvious, but I always find doors wide open during audits).
General building deficiencies.
Larger birds, such as Pigeons and Seagulls, typically cause more problems around the exterior of a facility on ledges, rooftops, HVAC units, loading docks and related areas.
In either case, these various types of pest birds can cause significant problems on the interior and exterior of food plants.
In most cases, facilities want to reduce as many conducive conditions as they can around and within the facility in a timely fashion. A conducive condition is one whereby due to a building condition, structural design, equipment operation, food or water source, or surrounding conditions (i.e., near a public landfill, raw materials mill or body of water) can attract pest birds to a facility. With each of these conditions, great care must be taken to reduce as many conducive conditions as possible.
Examples of Conducive Conditions
Loading docks/canopies with open beams and rafters
Pooling water (roof and landscaping)
Structural overhangs and ledges
Open access points
Landscaping (types of plantings)
Damaged truck bay bumpers
Gaps and opening around the structure
Doors with improper sealing
Employees feeding birds
Doors left open
All these conducive conditions, if left unresolved, can lead to significant bird problems. Reducing as many conducive conditions as possible will be the first step of any bird management program.
Bird Control Methods
From the start, your facility should have a bird management plan of action. For the most part, bird problems should not be left to be handled internally, unless your staff has been properly trained and has a bird management plan in place.
Most birds are protected by the Federal Migratory Bird Treaty Act of 1918. However, Pigeons, Sparrows, and Starlings are considered non-migratory birds and are not protected under this Act. Even though these three bird species are not protected, control methods still need to be humane. More specifically, your bird control program must also comply with is the American Veterinary Medical Association (“AVMA”) Guidelines for the Euthanasia of Animals if this is the control method selected. The AVMA considers the House Sparrows, Feral Pigeon, and the Common Starling “Free-Ranging Wildlife.” And Free-Ranging Wildlife may only be humanely euthanized by specifically proscribed methodology.
In addition to the above-mentioned regulations, various regulations regarding the relocation of birds/nests may also apply. I also always recommend checking with local and state agencies to ensure that there are no local regulations that may apply. Bottom line: Don’t rely on untrained internal practices; one misstep could result in heavy financial fines and penalties.
Bird Management Strategies
First Line Defense
Stop any bird feeding around the facility immediately
Any bird management plan should have a clear policy prohibiting employees from feeding birds. Once birds have been accustomed to routine feeding, the birds will continue to return.
Eliminate Standing Water Sources
All standing or pooled water needs to be eliminated. Thus, routine roof inspections need to be conducted to ensure drains are working properly.
Landscape irrigation needs to be calibrated to ensure no puddling of water in areas of low sun exposure.
Proper Sanitation Practices
Ensure that dumpster lids are closed when not in use.
Trash removal frequency adequate.
Routine cleaning of trash receptacles.
Immediate removal of spilled food.
Eliminate Entry Points
Survey the facility to ensure that all holes are properly sealed.
• Around truck bay bumpers and doors
Exhaust vents are properly screened.
Windows are closed and have screens when in use.
The most appropriate bird control strategy will be determined based on the severity of the bird pressure. For example, if the bird pressure is high (birds have nested), then in most cases, you will only be able to use bird exclusion methods. Whereas, if the bird pressure is light to moderate (birds have not nested), bird deterrent methods can be used. This is an important distinction. Bird exclusion is physically changing the area to permanently exclude said pest birds. Whereas, bird deterrent devices inhibit birds from landing on treated areas.
Bird Deterrent Methods
After the previously mentioned first-line strategies have been implemented, the next step would be to install bird deterrent products (birds have not nested).
Electrified Shock Track
Sonic & Ultra Sonic Devices
Lasers and Optical Deterrents
Hazing & Misting Devices
Bird Exclusion Methods
If the birds have nested in or around the facility, the next step would be to install bird exclusion products (birds have nested).
Ledge Exclusion (AviAngle)
Architectural modifying structural
Aggressive Harvesting (Targeting)
The best prevention strategy is planning and knowledge. Conduct a bird audit and develop a bird management plan before birds get near or inside the facility. The key is to act quickly, as soon as an incident occurs. I find countless times when I am called in to consult or service a food plant, that the birds got into the facility and no one knew what to do, and as a result, the birds remained within the facility for an extended period, thus increasing the risk of exposure. It is always much easier to remove a bird when they are unfamiliar with their surroundings. Whereas, it is much more difficult to remove birds from a facility that has had a long-standing bird problem.
Once you have a plan, who oversees the bird management plan? Are thresholds determined and set for various areas of the facility? For example, a zero threshold in production areas? Threshold levels will be set based upon by location and sensitivity of the said location. What steps are going to be taken to remove the bird? For how long is each step conducted? These questions need to be answered and developed to stay ahead of bird problems.
Reduce as many conducive conditions as possible. The longer a conducive condition stays active, the more likely birds, as well as other wildlife or rodents, will be attracted to the site and find a way into the facility.
Pathogen Contamination & Hazards
Birds present a host of problems, whether they are inside or outside of a facility. Birds can roost by air vents, and the accumulation of bird feces can enter the facility air system. Bird droppings on walkways and related areas allow for the possibility of vectoring of said dropping when employees step on droppings. Thus, spreading fecal matter/spores and other contaminants to areas throughout the facility.
If birds are within the facility, droppings can spread on product lines, raw materials, stored products, equipment and more, thus, causing contamination. Because of a bird’s ability to fly, they are perfect creatures to spread various diseases, pathogens, ectoparasites and fungal materials. Diseases such as Histoplasmosis, Salmonella, Encephalitis, E-coli, Listeria, and more. Birds have been known to transmit more than 60 infectious diseases!
Besides the spread of potentially harmful contaminants throughout the facility, bird droppings and nesting materials can also create a host of additional problems:
The acidity in bird droppings can damage building finishes, façade signs, lighting and more.
Wet bird droppings can create a slip and fall hazard.
Bird nesting materials can create a fire hazard around façade signs, exit signs and light fixtures.
Bird nesting and debris can clog roof drains and cause roof leaks from standing water.
Introduction of ectoparasites into the facility such as bird mites, lice, fleas, ticks and more.
In summary, taking a proactive approach to bird control is the best practice. Reduce food, water and shelter sources (aka conducive conditions) promptly. Pest management programs need to implement a more in-depth section of the program for bird control. Like integrated pest management, bird control should be based upon an integrated method. Each facility will have its unique challenges. As such, each bird management plan needs to be tailored to the specific site. A well designed and balanced, integrated bird management program will provide long-term and cost-efficient bird control.
As cannabis and CBD edibles and beverages gain in popularity among consumers, the rush to cash-in on market opportunities has resulted in an influx of unregulated and untested products. Recently the FDA increased its scrutiny of cannabis and CBD company websites and social media accountsto make sure they were not making unverified or misleading marketing statements about their products.
To exacerbate the problem of unregulated products, recent scares around vape-related hospitalizations have flooded the news, and the public is looking to the cannabis industry for answers about what it will do to ensure CBD and cannabis products are safe for consumption.
The first step the cannabis business community can take is educating the public on the two types of edibles— tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is heavily regulated. Every batch must be tested before it is released to retail ensuring labeling and dosages are consistent.
Since CBD does not have psychoactive properties, most products do not go through the same testing standards and are far less regulated. An estimated 75% of CBD-only companies do not test their products. Even worse, independent testing has shown that CBD labels are often incorrect or inconsistent with its dosage and ingredient labels.
Both cannabis and CBD companies must advocate for a more regulated and legitimate market. Stricter regulations and testing standards will eventually weed out the bad players who are hoping to make a quick buck from those that intend to manufacture quality products that can benefit the health of consumers.
Short Cuts To Boost Profits
The current vape pen crisis underscores the lack of regulation and inconsistency in the CBD market. CBD-exclusive vapes are more likely to use cutting agents, whereas licensed THC vape companies are more likely to use pure cannabis oils and are required to undergo quality control testing.
Using cutting agents may lower operating costs, but often results in an inferior or dangerous product. Cutting agents also inhibit crystallization in CBD oils and increase the shelf life of a product. The cost of production for pure THC or CBD oil is $5–6 per gram, but a cutting agent can reduce the cost down to $0.10–$2 per gram.
With edibles, untested CBD products can introduce Salmonella or E.coli into the supply chain. This oversight could severely hurt the reputation of growers and manufacturers if a serious outbreak occurred.
Learn more about important regulatory & quality issues in the cannabis space from Cannabis Industry JournalThe Solution Is in Testing
Unlike food manufacturing, where quality controls are in place at the plant, the quality measures for edibles happens in a lab, after a product is manufactured.
Labs test edibles for potency. Both THC and CBD are used for medicinal purposes, and potency testing is critical for accurate dosing. A patient under or over dosing, or taking a poor quality CBD product with additives could detrimentally affect their long-term health.
They will also test for product contamination. Both CBD and THC cannabis can become contaminated with microbes (i.e., mold, mildew, bacteria and yeast), pesticides and heavy metals throughout the process of growing, cultivation and processing. Contamination is especially concerning because many medical marijuana patients are immunosuppressed and cannot fight off potentially dangerous infections and illnesses arising from these contaminants.
But even for the general population, cannabis and CBD contamination can cause serious health issues. Molds and bacteria such as aspergillus, Salmonella and E. coli present safety risks, and toxicity from sustained exposure to heavy metals can lead to high blood pressure, heart issues and kidney failure, among other issues. Fortunately for consumers, cannabis products sold in licensed dispensaries must all undergo contamination and quality control testing per state regulations.
However, because quality control measures are not required for edible manufacturers, there is no oversight that food-grade ingredients are used or that practices to avoid cross-contamination are used.
What Companies Can Do To Win Back Trust
Customers around the country are rightfully concerned about the safety and quality of their cannabis and CBD products in light of recent news surrounding vape-related illnesses. This is the perfect opportunity for manufacturers and consumer brands to seize on the subject and educate consumers about cannabinoids so they aren’t turned off from incorporating CBD into their lifestyles.
First and foremost, test all products. At a minimum, companies should be adhering to state cannabis market regulations, even if they are just producing CBD. As the FDA rolls out more concrete regulations for CBD, which was only federally legalized last year, it is in the best interest of all CBD companies to meet FDA guidelines preemptively so products can pass inspection at a later date.
Find a good credible lab to help with formulations and inputs. With edibles and beverages, there is more room to introduce contaminants within that scope.
Hire food safety experts to help elevate safety standards and meet FDA regulations. Some forward-thinking companies are starting to hire quality experts from food manufacturing to get ready for broader federal acceptance.
Help educate consumers on why the brand is better, based on inputs and testing.
Consumers should also conduct their own research regarding individual CBD companies’ supply chains and manufacturing standards. Transparent companies will do this proactively, providing cultivation information and lab results for their customers.
In the end, the safest place to buy cannabis and CBD products is a licensed dispensary. It is the responsibility of growers, distributors, manufacturers and retailers to keep the legal market safe and free from contaminants that could threaten the industry. The regulated cannabis space has advanced significantly in the past few years, and companies must set the highest manufacturing standards to maintain this forward momentum. Education and testing are the best solutions to ensure a safe and trusted cannabis marketplace.
Recalls have become an unfortunate reality for the food and beverage industry. It seems every month, another grocer pulls inventory from its shelves due to contaminated products that are potentially harmful for consumers.
Last month, it was Kroger that was forced to remove beef products from stores in Ohio, Kentucky and Indiana as part of Aurora Packing Company’s recall of more than 62,000 pounds of meat that may have been infected with E. coli. Not only do these situations hurt the reputation and bottom line of companies across the food supply chain—from the manufacturer to the retail store—there is the potential for these issues to become deadly.
The 2019 Food Safety Consortium Conference & Expo features an entire track on sanitation | October 1–3 | Schaumburg, ILComplexities of the Food Supply Chain
The food industry faces unique supply chain challenges. First, consider that the industry is dealing with products that come from the ocean or earth. Once obtained, these products are boxed, sent, in many cases long distances, to a facility via truck or cargo ship, where our foods undergo a number of processing mechanisms before being put back in a shipping container and sent off to a store. When they finally make it in-store, they’re moved from the backroom to the store floor. After all this, these products go into our mouths and through our digestive systems.
There are often many complex steps food has to go through before it makes it into our homes—and with each level of the food supply chain comes a new opportunity for things to go wrong and contamination to happen. What makes the food supply chain even more frightening is that pinpointing the root cause of harmful pathogens—such as E. coli or Listeria—by retracing all the potential contacts points is very challenging given their microscopic nature. All in all, the germs are beating us.
Old Disinfection Techniques Aren’t Cutting It
To mitigate the issue of contamination and avoid those dreaded recalls, food companies have prioritized disinfection. Most often, techniques include manually washing processing equipment with chemicals to keep them sanitized, and even spraying food products with antibiotics to directly kill harmful germs. However, these solutions have many limitations and are either intermittent in their use or insufficient to tackle the complexity of challenges associated with the food processing environment.
First, the tide is beginning to turn on the use of chemicals on food products, with consumers having growing concerns with introducing antibiotics in their food. There’s heightened and justified skepticism over the use of antibiotics and fears over the potential impact on resistance through overuse. In other words, consumers are afraid of the potential side effects from ingesting these chemicals on a daily basis and the alternative resistance bacteria they promote.
The truth is that the excessive use of antibiotics makes them less effective. This is due to frequently exposed bacteria developing resistance to antibiotics over time. The result is that antibiotics are no longer as effective at killing these germs, which is at the heart of great concern for the public’s health.
Resistant bacteria can be passed from food-producing animals to humans in a number of ways. If an animal is carrying resistant bacteria, it can be passed on through meat that is not handled or cooked properly. Plus, food crops are regularly sprayed with fertilizers, which can contain animal manure with resistant bacteria. Once spread to humans, resistant bacteria can stay in the human gut and spread between individuals. The consequences of the introduction of these germs and the subsequent consumption of them include infections that would not have happened otherwise.
Second, cleaning equipment with chemicals and disinfectants is important, but only intermittently effective. While someone working in a food processing plant uses chemicals to clean off a surface or container before food touches it, there’s still an opportunity for harmful bacteria to land on the space in between washes from many sources including the air, packaging, other food, etc. Not to mention there is a wide variety of different surfaces and nodes that food touches as it moves throughout a plant and across the supply chain. Every single surface is a distinct and new opportunity for germs to live, and simply scrubbing these areas a few times a day (or once a day in some cases) simply isn’t enough to keep these germs away. By solely relying on the intermittent use of chemicals to sanitize, it seems virtually impossible to ensure contamination is not ever introduced along the way to your table.
The Introduction of Continuous Disinfection Using Light
Intermittent sanitization hasn’t been disproven to be a wholly effective way to kill germs—it’s simply not a strong enough line of defense in and of itself. Perhaps, one of the best ways to protect our food from harmful bacteria and prevent expensive recalls altogether is to introduce and layer in a new breed of “continuous disinfection” technology using bacteria-killing visible LED lighting directly into the process.
Going back to more than a century ago, scientists have known that certain wavelengths of light are highly effective at destroying bacteria. Ultraviolet (UV) light is extremely powerful, but it is also especially dangerous to humans and causes things like plastics to become brittle and crack. UV light directly impacts the DNA in people, animals and plants, along with bacterial cells.
There is, however, a very human-friendly frequency of light (405 nanometers), which is in the visible spectrum of light, that is completely harmless to humans, but just as devastating to bacteria. It activates the porphyrin molecules that exist only within unicellular organisms such as bacteria and fungi. Humans, animals and plants do not have these particular molecules. Exposure to 405 nm light directly activates these molecules and essentially rusts bacteria from the inside out destroying any bacteria that is exposed to this human-friendly light. The ability of this new LED tool to be safely used around the clock allows for it to be acting continuously. This continuous nature goes above and beyond the existing limitations of intermittent cleaning.
With the advent of LED lighting, it is now possible to “tune” the frequency of light with extreme precision. The significant breakthrough of isolating light to this specific frequency of violet-blue light has now begun to enter the food processing industry. It is taking its place as a critical component to the layered defenses against harmful bacteria entering the food chain. When left on, this light continuously kills bacteria, preventing any germ colonies from forming and replicating. This has now become the perfect complement to the proper cleaning and sanitizing of all surfaces used in food processing and preparation—intermittent chemical cleaning working together with continuous disinfection from light.
In short, avoiding outbreaks and infection crises is all about smart prevention. Recalls are a reactionary solution to the problem. The key to preventing these potentially deadly (and costly) situations is to make sure that all facilities that process and handle food are continuously disinfected. The good news is that tech startups are at the helm of developing these new tools for killing germs before they even have a chance to have a seat at our tables.
Last month Chipotle Mexican Grill closed a location in Powell, Ohio after nearly 650 reported illnesses were tied to the location. The outbreak was caused by Clostridium perfringens, a type of bacteria that thrives at room temperature—in other words, food at this particular Chipotle location may have been kept at unsafe temperatures.
As winter ends and summer approaches, most of us will emerge from our houses and start enjoying the nice weather. Even better, hopefully we all will be hosting or attending numerous BBQ’s and get-togethers. Burgers, chicken, salads and the like will be readily available; however, how can we be sure we’re keeping our food and guests safe from a foodborne illness?
The more hands and foods involved, the higher the risk of contracting a foodborne illness. Fortunately, today, we know much more about proper hygiene, food handling and preparation to combat these harrowing outbreaks.
According to the CDC, one in six Americans become ill due to foodborne illness each year. As the fight to combat this issue wages on, there are specific measures we can take to protect ourselves daily. While foodborne illnesses will likely never be eradicated, utilizing the ‘Core 4’ principles of food safety remain a viable approach to limiting its prevalence. This column outlines these ‘Core 4’ principles.
Infectious bacteria can thrive anywhere within the kitchen. By placing an emphasis on hand, utensil and surface washing, we begin to reduce the risk of foodborne illness. The following are some easy-to-follow cleansing tips:
Wash your hands for at least 20 seconds with soap and warm running water before and after handling food or using the bathroom.
Wash the surfaces of cutting boards, counters, dishes and utensils after each use with warm, soapy water.
Use paper towels to clean counters or spills as they soak in potential contaminants, rather than spread them like cloth towels.
Rinse or blanch the surfaces of fresh fruits and vegetables to rid of any dirt or bacteria.
Even though we now wash our hands and surfaces consistently, we can still be exposed to dangerous illness-inducing bacteria by not properly separating raw meat, seafood, poultry and eggs. To avoid cross-contamination, we can follow these tips:
Avoid placing ready-to-eat food on a surface that previously held raw meat, seafood, poultry, or eggs. An example would be: Placing your now-grilled chicken on the same plate in which you carried it to the grill.
Use separate cutting boards when preparing fresh produce and uncooked meats. This eliminates the spread of any bacteria either may be carrying to the other.
Request or separate raw meat, seafood, poultry and eggs in your grocery bags. This eliminates the spread of bacteria in the event there is an unsealed package.
Always properly wash the surfaces exposed to these raw items under warm, soapy running water.
Regardless of how proactive we are with cleaning and separating, we still must ensure that we cook our food to the appropriate internal temperature. Undercooking may result in the survival of dangerous bacteria that could make us ill. Foodsafety.org recommends the following safe minimum temperatures:
Steak/Ground Beef: 160°F.
Eggs: Until the yolk and white are firm; for egg dishes warm until 160°F.
Last yet not least, we must also learn to appropriately chill our food. Chilling is important because it decelerates the bacterial growth process. By mitigating this, it allows us to reduce the risk of contracting a foodborne illness. The following suggestions are encouraged:
For starters: Always keep your refrigerator at 40°F or below.
Do not over-pack your refrigerator. Proper airflow circulation is paramount.
Refrigerate any meats, egg, or perishables immediately upon return from the store.
Do not allow raw meats, egg, or fresh produce to sit out for more than two hours without refrigeration.
By taking these principles into consideration, you can ensure the protection of your friends, family and self, leading to better times and memories gained.
