The effect that the 1993 E. coli O157:H7 outbreak had on the food industry was tremendous. Responsible for more than 600 illnesses and the deaths of four children, the outbreak led to significant changes in the industry’s approach to food safety. “[It] drove a shift in food safety that many had been working toward for years,” said Rima Khabbaz, M.D., acting deputy director for infectious diseases at CDC during the “We Were There” CDC lecture series, adding that the focus moved to food suppliers and how they could make their products safer. “The outbreak drove a paradigm shift that opened the door to food safety,” said Patricia Griffin, M.D., chief of the CDC’s enteric diseases epidemiology branch during the lecture.

Within a few years, several actions and initiatives paved the way for notable progress. In 1994, Mike Taylor, who was administrator of USDA’s FSIS at the time, made a speech that “shocked and outraged the industry,” said Griffin, where he stated, “we consider raw ground beef that is contaminated with E. coli O157:H7 to be adulterated within the meaning of the Federal Meat Inspection Act.” From there, the USDA worked on the first major advance in meat regulation. In 1996 the agency established the Pathogen Reduction Rule to improve meat inspection. The same year CDC’s PulseNet was born, the nationwide lab network that uses DNA fingerprinting to help identify outbreaks early, along with the Foodborne Diseases Active Surveillance Network (FoodNet), an epidemiological system that tracks incidents and trends related to food.

In a Q&A with Food Safety Tech, Mike Taylor, most recently the former FDA commissioner for foods and veterinary medicine, discusses the dramatic change that industry has undergone during the past 25 years, from FSMA to technology advancements to food safety culture.

Food Safety Tech: Reflecting on how far the industry has come since the E.coli O157:H7 outbreak involving Jack in the Box in 1993, what key areas of progress have been made since?

Michael Taylor: I think there are very major ones obviously. You have to remember where things were when the Jack-in-the-Box [outbreak] happened. We were in a place where USDA programs said it was not responsible for pathogens in raw meat and that consumers are supposed to cook the product; [and] industry was operating under traditional methods. Microbial methods were typically conducted for quality not for safety; you had the loss of public confidence and a terrible situation in which consumers were pointing at industry, and industry was pointing at consumers, and no one was taking clear responsibility for safety of the product.

Now we are in a completely different environment where not only is there clarity about industry’s responsibility for monitoring pathogens, there’s also been enormous progress by industry to put in place microbial testing, something David Theno pioneered and is now a central part of food safety management systems for meat safety.

Everything has changed.

These [institutional] arrangements exist not only in the meat industry, but now across the whole food industry. There’s the emergence of GFSI taking responsibility for managing the supply chain for food safety, food safety culture taking hold broadly across leading companies in the industry, and FSMA codifying for 80% of the food supply that FDA regulates the principles of risk-based prevention and continuous improvement on food safety.

I think it’s rather dramatic how far the industry’s food safety regulatory system has come since [the] Jack in the Box [outbreak].

FST: How has FSMA helped to align industry priorities?

Michael Taylor FDA
Mike Taylor was on the front lines of change in the meat industry.

Taylor: Let’s focus on the events first leading up to FSMA—for example, the outbreaks or illnesses associated with leafy greens [and] peanut butter, and problems with imported products—those events in the world aligned industry priorities around the need to modernize the food safety laws and to enact FSMA. It was the coming together of industry and consumer interests, and the expert community around the principles of comprehensive risk-based prevention that vaporized into FSMA. Now FSMA is the framework within which companies are organizing their food safety systems in accordance with these modern principles of prevention.

And clearly what’s been codified in FSMA and some of the key elements are becoming organizing principles where industry is aligning our priorities for food safety. Environmental monitoring where that’s an appropriate verification control for a company’s hygiene and pathogen control—that’s clearly a priority that folks are aligning on. The issue of supplier verification for domestic and foreign supply is a priority that has been elevated by FSMA, and so has the whole issue of training and employee capacity, whether it’s in processing facilities or on farms, as well as food safety culture. If you’re going to be effectively preventive you need to deal with the human dimension of your food safety system.

These are examples of ways in which FSMA is aligning industry priorities.

Egg Contamination Spreads Across Europe

Egg

At least 17 countries have been hit with the European egg scandal involving insecticide contamination. Ground zero of the problem has not been definitively identified, as Belgium, the Netherlands and Germany are reportedly pointing fingers over which country is to blame and how long they knew about the problem. Dutch authorities may have known about the problem as far back as November 2016.

The eggs have been tainted with the pesticide Fipronil, doses of which are not harmful to humans engaging in short-term consumption. When consumed in large doses, it can cause damage to the kidneys, liver and thyroid glands.

Farmers in the Netherlands used a company, Chickfriend, to delouse their chickens, but this company reportedly mixed fipronil into the cleaning solution and could have contaminated nearly 180 farms in the country as a result, according to The New York Times. As many as 20% of Dutch egg-laying chickens could be affected. Chickfriend was recently raided by authorities and two of its directors were arrested. Antwerp-based Poultry-Vision stated that it provided Chickfriend with fipronil via a source in Romania, according to The Guardian.

Contaminated eggs, which have been distributed to at least 17 countries (mainly in Europe) have also been found at producers in Belgium, France and Germany, and as a result, millions of eggs have either been destroyed or removed from store shelves.

Sabrett hot dog recall

On Saturday the USDA announced a Class I nationwide recall of 7,196,084 pounds of hot dog products from Marathon Enterprises, Inc. Produced between March 17, 2017 and July 4, 2017, the certain beef and pork hot dog and sausage items may contain bone fragments.

The issue was uncovered via the FSIS Complaint Monitoring System on July 10, which stated that pieces of bone were found in the product. No injuries have been reported yet.

USDA Recall Classification of Class I Recall: “This is a health hazard situation where there is a reasonable probability that the use of the product will cause serious, adverse health consequences or death.”

FSIS has posted a full list of the recalled items on its website.

Adulteration with Sudan Dye Has Triggered Several Spice Recalls

By Thomas Tarantelli

Sudan dye

In the following article, the author reports finding Sudan dye in spices in New York State, making the argument for Class I recalls.

In New York State (NYS), Department of Agriculture and Markets food inspectors routinely sample domestic and imported food from retail markets for food dye determination. For decades, the NYS Food Lab has examined both domestic and imported food for undeclared allowed food dyes and unallowed food dyes utilizing a paper chromatography method. This method works well with water-soluble acid dyes, of which food dyes are a subset.

The NYS Food Lab has participated in four sets of the FAPAS proficiency tests: Artificial Colours in Soft Drinks and Artificial Colours in Sugar Confectionary (Boiled Sweets). The qualitative analysis was by paper, thin layer silica and thin layer cellulose chromatography. Satisfactory results were obtained.

The paper/thin layer chromatography method is a qualitative non-targeted method and has a limit of detection of approximately 1 to 5 ppm (parts per million) depending on the dye. If an unallowed dye is detected, the food product is violated as adulterated and results are forwarded to the FDA.

Some countries have a maximum concentration of allowed food dye in a food product. For example India has a 100 ppm to 200 ppm maximum for their allowed food dyes, in some food, singly or in combination.1

Sesame seeds, Rhodamine B
Early 2011, sesame seeds were found to contain Rhodamine B.

In early 2011, a food sample of pink colored sugar coated sesame seed from Pakistan was sent to the lab for color determination. The paper chromatography method could not determine any dyes. (As found out later, the unknown pink dye was not an acid dye.) From research it was found that Rhodamine B was a pink water soluble basic dye commonly used as a food adulterant.  A standard was ordered and then a qualitative high performance Liquid chromatography-tandem mass spectrometry (HPLC/MS/MS) method was developed (Waters UPLC Aquity w/Waters Premier XE triple quadrapole) to determine Rhodamine B. After utilizing this new method, Rhodamine B was found in the sugar coated sesame seed.

Rhodamine B is an industrial dye and is not allowed in food anywhere in the world. Industrial dyes are not allowed in food because they are toxic; in fact, some industrial dyes are used for suicide.2,3,4 In addition, industrial dyes are not made to “food grade” specifications with regard to dye purity, heavy metal (i.e., arsenic and lead) concentrations, subsidiary dye concentrations and concentrations of unreacted precursors. From additional research of news articles and research papers, more industrial dyes were identified as common food adulterants; more dye standards were ordered and incorporated into the HPLC/MS/MS method. The NYS Food Lab’s current HPLC/MS/MS surveillance method includes 36 compounds: Water soluble “acid dyes” and “basic dyes”, organic solvent soluble “solvent dyes”, and several pigments.

The HPLC/MS/MS method has a limit of detection in the ppb (parts per billion) range for some dyes and parts per trillion for other dyes. The FDA has an action level of 1 ppb for certain water-soluble basic dyes (such as Malachite Green) when used as a fish antibiotic. However, due to concern that unallowed dyes might be present due to contamination from packaging, the food lab subsequently set an action level of 1 ppm for unallowed dyes determined by the HPLC/MS/MS method. At levels over 1 ppm, detection of dyes in food would indicate intentional dye usage for coloring food.

The food lab has participated in three rounds of the FAPAS proficiency test, “Illegal Dyes found in Hot Pepper Sauce”. The qualitative analysis was by LC/MS/MS. Satisfactory results were obtained.

Sudan Dyes Considered to be Carcinogenic

“Sudan dyes are not allowed to be added to food. There has been worldwide concern about the contamination of chili powder, other spices, and baked foods with Sudan dyes since they may have genotoxic and carcinogenic effects (according to the International Agency for Research on Cancer)”.5

“There have been several documented cases of spices being contaminated with carcinogenic dyes such as Sudan I or lead oxide. We therefore assume that the presence of these chemicals in spice ingredients will be considered a reasonably foreseeable hazard under this rule.”6

“Sudan red dyes have been used to color paprika, chili powders, and curries, but are also known carcinogens and are banned for use in foods.” 7

Sudan Dyes are a family of more than 10 synthetic industrial “solvent dyes”. Solvent dyes are typically used to color oils and waxes, including shoe polish. Sudan dyes that the food lab has found in spices include Sudan 1 (Sudan I), and Sudan 4 (Sudan IV). Sudan 1, also known as Solvent Yellow 14, is an orange colored dye. Sudan 4, also known as Solvent Red 24, is a blue shade red colored dye.

Positive identification of Sudan 4 is often hindered by the existence of a positional isomer, Sudan Red B (Solvent Red 25). This problem was addressed by using the HPLC/MS/MS method with a transition unique to Sudan 4 (381.2 > 276.0). This information was obtained from one of the two corroborating labs. The food lab has recently identified a transition unique to Sudan Red B (381.2 > 366.1).

Sudan Dyes Found in Spices in Europe

In March 2001, Europe began discovering Sudan dyes in spices. A February 2017 search of Europe’s Rapid Alert System for Food and Feed (RASFF) for “unauthorised colour” and “sudan” in the “herbs and spices” food category resulted in 429 notifications.

The 429 RASFF notifications arranged by year and by maximum concentration reported of Sudan 1 and Sudan 4 during that year are listed in Table I.

In a search of the FDA’s Import Alert 45-02 (Detention Without Physical Examination and Guidance of Foods Containing Illegal and/or Undeclared Colors) the author could find no record of spices violated for Sudan dye adulteration.

In a search of the FDA’s Enforcement Reports the author could find no record of spices violated for Sudan dye adulteration.

Industrial Dyes in Food: Class II or Class I Recall?

The NYS Food Lab and the FDA routinely find imported food containing unallowed food dyes such as Ponceau 4R, Amaranth and Carmoisine. These unallowed food dyes are allowed for use in food in other parts of the world, while not allowed in the USA. Foods containing unallowed food dyes are violated as adulterated and a Class II recall will occur. Sudan dyes are not allowed as food dyes anywhere in the world. They are industrial dyes, used in coloring oils and waxes, such as shoe polish.

“Class I recall: A situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.

Class II recall: A situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.”8

With a Class II recall, there is no consumer notification. In contrast, as part of a Class I recall, a press release is issued. Consumers who have purchased the product might be informed and may discard the product or return it for a refund.

The Reality: Pests Cause Product Contamination

Product pests, Rentokil

While it may seem obvious to many food companies that a pest infestation can lead to significant product contamination, on a global scale not all regions are on top of this problem. According to a recent research conducted by Rentokil, 82% of U.S. businesses are proactive about pest control, but the percentage falls to 68% in the UK and dips a bit lower to 65% in France. This is significant because pests such as cockroaches, flies and birds can cause serious contamination such as Salmonellosis and E. coli as well as facilitate the spread of diseases through their droppings.

The following infographic from Rentokil outlines the problems that pests can cause and methods food companies can use to fight contamination.

Last year, nearly 550 food products were recalled in the United States. Nearly half of those recalls were a result of biological contamination, a whopping 65% of which was due to Listeria monocytogenes, according to Rentokil. The company recently released an infographic about the cost of a product recall, pulling out some of the key trends in food product recalls in the United States and the United Kingdom. Next to biological contamination, mislabeling continues to be a large issue.

Sanitation Solutions for Pest Problems

By Tim Husen, Ph.D.

Tim Husen, Rollins Technical Services

It’s no surprise that food manufacturing and processing environments are naturally vulnerable to food safety threats. Food processing environments have all the things a pest needs to thrive: Food, water and shelter. And if poor sanitation is added to the mix, pests can find your food processing plant absolutely irresistible.

An unkempt facility can attract flies, ants, cockroaches and other unwanted common pests such as rodents. All of these common pests could put you or your facility at risk during your next audit.

The good news is pest-related sanitation issues are preventable through proactive and holistic preventive treatment plans. It’s important to establish proper sanitation processes and procedures so that over time, you avoid or reduce the occurrence of pest problems that could cost you major points on an audit and potentially compromise your products.

Many food processing facilities employ integrated pest management (IPM), an approach that helps prevent pest activity before it occurs and uses chemical treatments only as a last resort. The goal with these types of treatments is to give facility managers tools to use in advance of their next audit to stay ahead of pests, to teach employees good practices and to avoid problems before they happen. A good IPM program includes careful documentation of pest issues and the conducive conditions relating to them, as well as any corrective actions taken to resolve them. This documentation is incredibly important not just in solving pest problems, but also in its relevance to FSMA regulations.

When talking to pest management providers, remember that a “one-size fits all” strategy often doesn’t work, so expect your pest control company to recommend a customized plan. Different environments have different “hot spots” (areas where pests typically are present if the conditions are right) and face different pest pressures. However, there are a few key best practices that can be applied to any facility to help protect against pests.

The following guidelines will help to minimize pest activity and prepare for your facility’s next audit.

1. Educate and Enlist Your Employees in the Fight Against Pests

The first step to establishing your sanitation plan is enlisting your staff. One of the strongest building blocks in your defense against pest activity is sanitation. This key component of your IPM plan begins with the vigilance of your employees. Sanitation and pest management aren’t one-and-done tasks. They’re ongoing and you’ll get the best results when the entire staff is on board.

How can they help? Your employees are often the first to notice any potential signs of existing problems, so it’s important to educate them on hot spots where pests could live, what signs they should look for, and what to do if they see a pest issue. Once your employees understand the importance of sanitation, set a zero-tolerance policy for spills, debris and waste. If employees spot a pest, make sure they understand the protocols for documenting its presence. Consider implementing daily, weekly and monthly sanitation routines in addition to an annual deep cleaning.

Finally, enlist your employees to help keep common areas clean, from break rooms to locker rooms. Establish processes to clean up dirty dishes and drink spills, and empty full trash bins immediately. Don’t forget about cleaning the bins themselves! Also, make sure that common refrigerators aren’t filled with past-expiration lunches or snacks. If you’re finding it tough to get employees to participate, most pest management providers will offer a free education program to make employees aware of potential risks and what they can do to help. Sometimes it can help employees to hear from the experts.

2. What’s on the Inside Counts

As the saying goes, what’s on the inside really matters. This is true for the interior sanitation of your processing facility, too. There are a few particularly vulnerable hotspots to be conscious of when putting together your sanitation plan, especially the production floor, the storage areas and the receiving areas.

For obvious reasons, the production floor is one of the most important areas of focus for your sanitation program. Any hygiene issue could directly impact and expose your food products to contamination. Pests love to make their homes in big equipment that is often difficult to access for cleaning. Improper sanitation may lead to bacteria growth on the production line, which poses a major food safety threat. Create a schedule so that all equipment and machinery are sanitized regularly, and don’t forget about paying extra attention to those out-of-sight areas.

Drain flies and other pests live around drains and drain lids. Both should be scrubbed and sanitized regularly to prevent buildup of grease and other gunk that can attract pests. Organic, professional cleaning solutions are a great option to break down tough stains and grime on floors and around drains. These organic cleaners use naturally occurring enzymes and beneficial bacteria to degrade stains, grime and other organic matter build up, which helps reduce the likelihood of drain flies and other pests.

Storage areas are also prone to attracting pests and the potential bacteria they harbor. These cluttered spaces can get filled with extra boxes and other debris, and are perfect locations for pests to hide. Keep these areas clean and clear of clutter so pests have fewer areas to seek shelter and reproduce.

Cockroaches especially love cardboard boxes, so take those to recycling facilities regularly. Remove any equipment that is not being used. If you have re-sealable containers, clean out all the containers before placing new products inside. All containers should be tightly sealed and kept six inches off the floor and 18 inches away from walls. You can also affix mops and other types of cleaning equipment to the wall. Keeping them off the ground will keep them dry and prevent them from sitting in standing water, which is a major hot spot for fly breeding and bacteria build up.

Don’t forget that pests are experts at squeezing under receiving doors and sneaking onto shipments. To prevent unwanted stowaways, ensure your exterior doors form a tight seal when closed and always give delivery trucks and incoming shipments a thorough inspection for pest activity. Pests love to sneak into any opening they can find, so keep building exits, loading docks and other entrances closed as much as possible. Install weather stripping and door sweeps to keep pests out by creating a tight seal around openings. Believe it or not, rats can squeeze through a hole the size of a quarter, mice through a gap the size of a dime, and crawling insect pests through spaces barely noticeable to the human eye. For other cracks and crevices, use weather-resistant sealants to close any openings and consider installing metal mesh for an extra layer of protection against rodents that can gnaw openings to get inside.

3. Don’t Forget the Great Outdoors

To keep your exterior spic and span, create and maintain a regular sanitation schedule for your building’s exterior so it doesn’t become a haven for pests.

Regular pressure washings of sidewalks and walls will knock away any debris or build-up on exterior surfaces and could help remove any bird droppings around the property that could be brought inside by foot traffic. While it seems like a no-brainer, keep dumpsters and recycling collections as far away from facilities as possible, and make sure they are cleaned and sanitized frequently. And like interior cleaning best practices, don’t neglect areas above or out of the line of sight like gutters and rooftop ledges. Sometimes, leaves, standing water and other debris can build up over time, which provides breeding areas and shelter for pests—­especially mosquitoes.

Did you know that flies are not just attracted to food processing facilities because of food smells, but also for their exterior lighting? Flies and other flying insects are attracted to light and may use it for orientation. Mercury-vapor lighting is especially attractive to flies, so consider swapping mercury-vapor lamps next to entryways with sodium-vapor lights or LEDs. And to lure flies away from your building, place your facility’s mercury-vapor lighting at least 100 feet from entrances. It is often important to remember that the best option is always to direct lighting towards a building rather than mount lighting on it.

Good outdoor pest maintenance also includes landscaping. Trim your trees often and keep plants at least 12 inches away from your building. This decreases the chance of pests using vegetation as breeding or nesting grounds and the chances they’ll get access to your facility. Standing water often becomes a breeding site and moisture source that could provide pests like flies, mosquitoes and rodents with water necessary for survival. Remove any standing water around your building to prevent this and remove any reason for those pests to stick around. Look for stagnant water in gutters, ponds, birdbaths, water fountains and any other places that water could sit for more than a week without moving.

These proactive pest management tips will be useful in protecting your building and products from food safety threats. If there are any tasks that require additional help, consider talking to your pest management provider about creating an IPM plan. They will walk through your facility with you to identify any hotspots and suggest potential corrective actions—you’ll be glad you did when it’s time for your next audit.

Golden Gourmet recall

Over the past few days, there have been two more large meat recalls. In both cases, there have been no confirmed reports of adverse reactions due to product consumption.

Golden Gourmet Recall

Golden Gourmet has recalled more than 5,000 pounds of frozen waffle and turkey sausage products over concerns of contamination with Listeria monocytogenes. The issue was uncovered when the company received a letter of notification from US Foods, its supplier, that products had been recalled. The Class I recall involves products that were produced and packaged on December 21, 28, 29 and 30, 2016 and shipped to locations in Georgia, Iowa, Illinois, Ohio, South Carolina and Tennessee.

Armour Eckrich Meats Recall

FSIS also announced a Class II recall initiated by Armour Eckrich Meats, LLC over concerns of metal contamination. The company recalled nearly 91,000 pounds of ready-to-eat fully cooked pork, turkey and beef breakfast sausage products that were produced and packaged from April 26 through April 28, 2017 and shipped to distribution centers in Arkansas, Indiana, Kansas, Louisiana, Oklahoma and Texas. Armour Eckrich Meats discovered the problem when it was notified by an FSIS-regulated establishment that pieces of metal were embedded in the sausage product produced by Armour Eckrich.

Indicon Gel, biofilm

The food processing environment is ripe with hot spots where biofilm can hide. A rapid biological hygiene indicator in the form of a spray gel has been developed to provide companies with a visual indication of biofilm on a surface. Once the gel makes contact with biofilm it produces foam within two minutes. Manufactured by Sterilex, Indicon Gel does not require mixing and is appropriate for seek-and-destroy missions. It enables detection of microorganisms that include Listeria, E.coli and Salmonella on both large surfaces as well as niches that cannot be accessed by a swab.
