Ask the Expert: Keeping Flies Out of Your Facility

Frank Meek, Orkin

Food companies have to manage a variety of pests seeking harborage, food, water and other resources in their facilities. Among these pests, flies can be some of the most difficult to manage. Frank Meek, technical services manager for Orkin and board-certified entomologist with 36 years’ experience in the food industry, shares strategies to you can take to mitigate the risk of flies in your food facility.

Why are flies such a problem for food companies? 

Meek: Flies are prolific breeders, carriers of multiple potential pathogens, vectors of contamination and a costly pest for food manufacturing and processing facilities if not handled appropriately. One female fly can create hundreds of eggs in five or six days and potentially introduce many microorganisms and pathogens. 

Which types of flies pose the greatest risk to food establishments?

Meek: The types of flies most likely to impact food-handling establishments are:

  • “Filth” flies, which can transmit bacteria and other pathogens to surfaces
    • Attracted to odors first, then food waste, organic build up, sewage and feces
    • g., house flies and blow flies
  • “Nuisance” flies, which typically do not transmit pathogens, but can still cause harm
    • Attracted to overripe or decaying fruits, vegetables or other organic materials
    • g., fruit flies, drain flies and phorid flies

How can you keep flies from entering your facility?

Meek: Flies don’t need a lot of space to get in and out of buildings. They typically enter buildings through frequently opened doors and improperly sealed openings such as drains/pipes, ventilation systems and windows. Because of this, exclusion—using preventive methods to help eliminate pest entry points—will help to keep flies out.

  • Seal any unplanned cracks, holes and crevices as soon as you notice them to avoid pests accessing your building.
  • Seal all doors and windows with weather stripping.
  • Limit direct lighting around the entrances of your facility.
  • If you must have lighting near the entrances, use sodium-vapor light bulbs, as these are less appealing to insects than fluorescent bulbs (which draw pests in, especially at night) or indirect lighting.

The best way to deter flies is to seek a pest control provider that offers an Integrated Pest Management (IPM) program. A successful IPM program is proactive, environmentally conscious and addresses the reasons pests are attracted to your facility. IPM is a team effort between you and your pest control provider. Once implemented, your IPM program should be reviewed at least annually with your pest management professional to ensure continued improvement.

How can facilities improve sanitation methods to prevent infestations?

Meek:  Ensure you have a rigorous sanitation routine that addresses high and low pest-pressure areas within your facility. If you already have a schedule, work with your pest control provider to review it so it includes the following:

  • Keep dumpsters and trash cans as far away from the facility as possible.
  • Work with your waste management company to routinely clean or rotate your dumpster.
  • Install odor control devices where needed to eliminate foul smells that might attract flies.
  • Remove trash, debris and food from areas like employee lockers or breakrooms multiple times throughout the day.
  • Keep tight lids on interior trash receptacles, change the liners daily and regularly clean out the bottom of the bins.
  • Sanitation teams should also regularly clean machinery that handles food, as joints and crevices can build up organic matter and attract pests.

If you have a fly infestation, how do you get control of that and reduce future issues?

Meek: There are several steps you can take to control and prevent infestations. They include:

  • Sanitation Routine: should be rigorous to help eliminate fly eggs, habitats and attractants
    • Work with your pest control provider to review your current cleaning program and make any needed changes to frequencies.
    • At times, non-residual and / or residual pesticide application may be needed to help reduce populations
  • Traps and Fly Lights: monitor the efficiency of your overall fly control program, but they are not a complete control option
    • Mechanical traps can be used in many areas of your facility. Your pest control provider can work with you to determine the best locations and type of device needed.
    • Installing fly lights will allow you to monitor fly activity.
  • Employee Training: can help catch pest issues before they become a bigger problem
    • Work with your pest control provider to train your staff on how to spot and report signs of pest activity.
    • Most pest control providers offer complimentary staff training that clarifies the role your employees play in preventing pest infestations.

How to Keep Pathogen-Spreading Pests Out of Your Business

By Frank Meek

Frank Meek, Orkin

As food processors and retailers work tirelessly to feed the public during the current global health pandemic, pests continue to work overtime to keep their food supply on track. Filth flies, cockroaches and rodents, in particular, pose a threat to the food supply chain, especially with concerns of the transmission of pathogens at an all-time high. The last thing your business needs is an avoidable food safety incident that threatens your reputation and bottom line.

When it comes to food safety, pathogen-spreading pests have no place in your facility and pose a major public health risk. Not only can these filthy pests become a nuisance within your facility, they can also contaminate your products and spread foodborne bacteria such as Salmonella, E. coli and Listeria, which can cause illnesses.

Knowing what attracts these pests to your facility and the dangers they pose is important for effective removal. Let’s dive into the signs of cockroaches, filth flies and rodents, and the specific concerns they can cause.

Frank Meek will share his expertise during a complimentary  webinar on March 4, “Making the Grade: Tips for Passing Food Safety Audits During the Pandemic” Cockroaches

Cockroaches seek four things that food processing facilities provide in abundance—food, shelter, proper temperatures and water. With the ability to squeeze through tiny gaps and cracks, these dirty pests enjoy crawling under equipment, in cabinets and through drains to find their next meal. Cockroaches can be found in and around almost any place within your facility. They’re capable of carrying harmful bacteria that they can spread from one location to another. Look out for droppings, cast skins or egg cases, which might signal a cockroach problem.

Filth Flies

You may think these types of flies have no desire to be inside, but they are in fact happy to go wherever the conditions are right. The most common filth fly is the housefly. These winged pests can carry and spread more than 100 disease-causing pathogens including bacteria, fungi and viruses. These can cause illnesses such as cholera, dysentery and infantile diarrhea. Filth flies in your facility can lead to a major public health issue if your food becomes contaminated.

Rodents

One of the filthiest pests around, rodents can contaminate your food supply, destroy or consume products and cause structural damage to your facility. Like cockroaches, mice and rats can fit through relatively small spaces to find food and water. With sightings on the rise during the COVID-19 pandemic, you’ll want to keep an eye out for rodents near your food products. These mighty chewers pose a public health threat as they can transmit diseases such as hantavirus and lymphocytic choriomeningitis (LCM) via their urine and droppings.

The presence of these vermin in your facility threatens public health. Additionally, an infestation can slow down the supply chain by causing businesses to recall contaminated foods.

A rigorous sanitation routine is one of the most effective ways to proactively manage pests like cockroaches, rodents and filth flies. Regularly sanitizing and disinfecting your facility can help eliminate any pathogens left behind on hard surfaces and remove the attractants for which they search. While cleaning removes dirt and buildup, sanitization and disinfection kill bacteria and pathogens, reducing the risk of a food safety issue.

Including the following tips in your cleaning routine can help keep your products and reputation safe from harm.

  • Clean out drains routinely with an enzymatic cleaning solution that can break down the organic grime.
  • Disinfect high-touch hard surfaces with a proper and low-toxicity disinfectant to kill bacteria and pathogens that can cause food illnesses.
  • Move dumpsters away from your building to reduce flies being attracted to and then gaining easy entry into your facility.
  • Wipe spills as soon as they occur to prevent them from becoming a sticky paradise for flies and cockroaches.
  • Practice good hygiene in your work environment and ensure employees are washing their hands regularly and keeping break rooms free of trash and leftovers.

Implementing exclusion practices such as sealing cracks, gaps and holes in walls with a proper sealant can also help you keep pests out. Budget allowing, consider investing in insect light traps and mechanical traps to help reduce flying insects inside.

Communication with your suppliers and distributors is also important to ensure food safety. If your partners implement similar measures, you’re more likely to protect the public from harmful diseases. Furthermore, customers will continue to trust your business.

While following these tips can help reduce the chances of a pest infestation, it’s not always possible to keep pests and the pathogens they spread out of your food processing facility. Work with a trained pest control specialist to develop a customized prevention program for your business as each type of pest requires specific treatment. They can also help you schedule inspections to identify conditions in and around your facility that may attract flies, cockroaches and rodents, among other pests.

Stay Audit-Ready, Anytime with Integrated Pest Management

By Chelle Hartzer

Chelle Hartzer, Orkin

The unlimited supply of food sources that manufacturing facilities provide can make pest management a daunting task, especially with the scrutiny of third-party auditors, government regulators and customers. These high standards, along with yours, mean that diligence is a key ingredient in the recipe for pest management success.

Why is this important? The steps you take to prevent pests, and how issues are resolved if pest activity is detected, affects the overall credibility of your business. After all, pest management can account for up to 20% of an audit score.

Auditors look for an integrated pest management (IPM) plan, which includes prevention, monitoring, trend reports and corrective actions. If you want to stay audit-ready, all the time, implement the following five principles.

Open Lines of Communication

A successful pest management partnership is just that: A partnership. Create an open dialogue for ongoing communication with your pest management provider. Everyone has a role to play from sanitation to inspection to maintenance. For example, if there are any changes in your facility, such as alteration of a production line, let your provider know during their next service visit. During each visit, it’s important to set aside time to discuss what was found and done during the visit, including new pest sightings and concerns.

Communication shouldn’t be limited to the management team; your entire staff should be on board. During their day-to-day duties, employees should know what to look for, and most importantly, what to do if they notice pests or signs of pests. Reporting the issue right away can make a huge difference in solving a pest problem before it gets out of hand. Also, most pest management providers offer staff training sessions. These can be an overview of the basics during your next staff meeting or a specialized training on a pertinent issue.

Inspect Regularly

A thorough inspection can tell you a lot about your facility and the places most at risk for pests. Your pest management provider will be doing inspections every visit, but routine inspections should be done by site personnel as well. Everyone at the site has a set of eyes, so why not use them? This way, you can identify hot spots for pests and keep a closer eye on them. Pests are small and can get in through the tiniest of gaps, so some potential entry points to look out for are:
• Windows and doors. Leaving them propped open is an invitation for all sorts of pests. Don’t forget to check the bottom door seal and ensure it is sealed tight to the ground.

  • Floor drains. Sewers can serve as a freeway system for cockroaches, and drains can grant them food, water and shelter.
  • Dock plates. A great entry point for pests, as there are often gaps surrounding dock plates.
  • Ventilation intakes. These are a favorite spot for perching, roosting or nesting birds, as well as entry points for flying insects.
  • Roof. You can’t forget about the roof, as it serves as a common entry point for birds, rodents and other pests.

Another thing to look for is conducive conditions, such as sanitation issues and moisture problems. These are areas where there may not be pests yet, but they provide a perfect situation that pests could take advantage of if they aren’t dealt with. Make sure to take pictures of deficiencies so that can be shared with the maintenance department or third-party who can fix it. You can also take a picture of the work when it has been finished, showing the corrective action!

Keep It Clean

Proper sanitation is key to maintaining food safety and for preventing and reducing pests. You need a written sanitation plan to keep your cleaning routine organized and ensure no spots are left unattended for too long. The following are some additional steps consider:

  • Minimize and contain production waste. While it’s impossible to clean up all the food in a food processing site (you are producing said food!), it’s important to clean up spills quickly and regularly remove food waste.
  • Keep storage areas dry and organized.
  • Remember FIFO procedures (first in, first out) when it comes to raw ingredients and finished products.
  • Clean and maintain employee areas such as break rooms and locker rooms.
  • Ensure the outside of your facility stays clean and neat with all garbage going into trash cans with fitted lids.
  • Make sure dumpsters are emptied regularly and the area around them kept clean.

Monitoring

Monitoring devices for many pests will be placed strategically around your facility. Some common ones are insect light traps (ILTs), rodent traps and bait stations, insect pheromone traps and glue boards. It’s important to let employees know what these are there for and to respect the devices (try not to run them over with a fork lift or unplug them to charge a cell phone). These devices will be checked on a regular basis and the type of pest and the number of pests will be recorded. This data can then be analyzed over time to show trends, hot spots, and even seasonal issues. Review this with your pest management provider on a regular basis and establish thresholds and corrective actions to deal with the issues when they reach your threshold. The pest sighting log can also be considered a monitoring tool. Every time someone writes down an issue they have seen, this can be quickly checked and dealt with.

Maintain Proper Documentation

Pest management isn’t a one-time thing but a cycle of ongoing actions and reactions. Capturing the process is extremely important for many reasons. It allows you to analyze, refine and re-adjust for the best results. It’s a great way to identify issues early. Also, it’s a critical step for auditors. Appropriate documentation must be kept on hand and up-to-date. There’s lots of documentation to keep when it comes to pest management and your provider should be keeping all of that ready—from general documentation like your annual facility assessment and risk assessment to training and certification records, pest sighting reports, safety data sheets and more.

The documentation aspect may seem like a lot at first, but a pest management provider can break it down and make it easier. It’s absolutely necessary for food and product safety and will become second nature over time.

Don’t Let Pests Wreck Your Supply Chain

By Chelle Hartzer

Chelle Hartzer, Orkin

In today’s global marketplace, it has become necessary for facility managers to implement more detailed inspection and documentation policies for incoming shipments as part of the larger food safety plan. But plan as you might, pests are adept at infiltrating food products and contaminating shipments. Their resilience and persistence will make you pay, literally, if you’re not paying close attention.

Pest management is a key component of any facility manager’s food safety plan, but understanding how best to prevent pests from compromising shipments—and by extension the supply chain—takes diligence. An integrated pest management (IPM) program is the best way to ensure that insects and rodents are kept away from processing, packaging and storing food products. Again, this information shouldn’t be anything new if you’re a food processing facility manager, but it’s important to note that IPM focuses on proactive prevention of pests, to align with FSMA’s Hazard Analysis and Risk-Based Preventive Control (HARPC) regulations. These newer regulations shift the focus from reacting to potential contamination concerns to preventing as many issues as possible. Being proactive is a must.

Aside from the legal backlash a facility could face if found if violating these rules, pest issues can also have a major negative impact on a business’ bottom line. Imagine the cost of even one of your outgoing shipments being contaminated by cockroaches or stored product pests. Now, imagine the impact on your business from consumer backlash if the pest-ridden shipment travels further down the line. Simply put, it’s never good if the pest problems are traced back to your facility.

So, what’s the best way to protect your supply chain from potential pest issues and remain compliant under FSMA and HARPC?

All food safety plans should have considerations in place based on a review from a Preventive Controls Qualified Individual (PCQI). This individual is responsible for preparing the document, with the input of as many departments and people as possible, such as QA/QC, maintenance, production teams, and more. Since pests are a common potential hazard, a pest management program should be included in the plan.

That being said, it’s important to inspect all incoming shipments. Even if suppliers have implemented measures to help keep pests away from their sites and products, pests are tough to entirely prevent and it’s always a possibility some have slipped through the cracks (literally!). Pests are attracted by food, water and shelter, so a truck transporting products to your facility is going to be chock-full of attractants! Carefully inspecting incoming shipments will not only help ensure pests don’t enter your facility, but it will help you and your supply chain partners target exactly where problems may be occurring. Forming good relationships with your suppliers, and keeping communication open can help to manage any issues that may pop up.

The faster pest issues are detected, the better. It’s easier to address a pest problem and more accurately pinpoint where it originated if it can be caught early. Otherwise, pests can reproduce quickly and spread, making it harder to pin down the source of an infestation and to treat it. It’s tough to overstate the importance of open lines of communicated between supply chain partners!

To avoid allowing pests into your facility or sending them to a supply chain partner, implement the following processes:

  • Inspect shipments for pest activity, especially incoming shipments. Some common signs include live or dead insects, droppings and damage to the product and packaging.
  • Ensure packaged products are properly sealed and undamaged before transport, and then check the transportation vehicle before loading product for shipping.
  • If there is a pest sighting, remove any compromised product to avoid allowing pests to spread to other goods or find a way into the facility. If it can’t be removed from the facility, isolate it in a contained area and call your pest management provider immediately.
  • Empower employees to call out pest issues as well by implementing a “see something, say something” policy. Don’t forget to have a pest sighting log, and let the employees know where it is and what to record.
  • Use monitoring devices to detect pest activity levels. Devices like insect light traps, pheromone monitors, and glue boards can be easily placed in shipping and receiving areas as an early warning sign of pest activity.

With an untrained eye, pest issues can be difficult to notice. Ask your pest control professional about a free training session for employees. Most pest management companies offer this service free of charge, and it can be a big help. There’s no reason you shouldn’t take advantage.

The pest pressure a facility faces is dependent on a variety of factors including location, geography and the type of product being produced and stored. No two facilities are the same, which is why every pest management program should be customized to meet the needs of the business.

As a start, the following pests are the most common to find in the food processing industry.

  • Rodents: Rats and mice can carry disease-causing pathogens that can be deposited onto other surfaces by simply making contact with equipment or products. Both are capable of fitting through tiny gaps (mice can fit through a hole the size of a dime, while rats can fit through a hole the size of a quarter), meaning any openings on the exterior of a building serve as a welcome mat to a curious rodent. To spot the signs of rodent activity, look for droppings and yellowish-brown grease marks around corners and along baseboards, as these marks can be caused as a rodent rubs against these areas. In addition, look for gnaw marks around any gaps or openings in walls and on products.
  • Cockroaches: Able to squeeze their bodies through miniscule gaps, cockroaches will feed on just about anything. With a good food source, they can reproduce quickly. A couple cockroaches can become an infestation in a matter of months, especially with an abundant food supply. Cockroaches are most active at night, so if you see one during the day it’s a good sign that it’s time to act quickly!
  • Flies: While less likely to find their way into packaged products, flies can spread dangerous, potentially disease-spreading pathogens on everything they touch. They usually don’t travel too far from their larval food source, but their ability to reproduce quickly can make them a nightmare to get rid of if steps aren’t taken to remove them immediately.
  • Stored Product Pests: There are numerous kinds of stored product pests, but all are adept at thriving in and around products undetected. The Indian meal moth, for example, is a moth with small, cream colored larvae that will eat just about anything. Stored product pests are some of the most likely pests you’ll find on incoming shipments and in storage areas, as they’re right at home breaking into and surviving within product packaging.

Keep these pests on the radar, and make sure to take note of where pests are found and how many are spotted. The more information, the better, as it helps pest management professionals get to the root of pest problems.

Documentation is always a major key. It shows an auditor that careful planning and proactive prevention are points of emphasis, which will be important. Although there are numerous documents to keep on hand, add the following to your list in order to more easily demonstrate compliance with pest related FSMA regulations:

  1. Supply chain program, including suppliers and ingredients.
  2. Receiving procedures, including the pest management program that helps prevent pests from entering the facility on products or through loading areas.
  3. Receiving records, or, in other words, documentation of shipments received from suppliers.
  4. Monitoring records of any captured pests in or around the facility and any corrective actions.
  5. Application records for treatments used in and around the facility.

If suppliers are located in another country, note the requirements differ from facilities located in the United States. The FDA breaks this down on their website, but importing products from another country means a facility must follow the Foreign Supplier Verification Program. This comes with a different set of compliance documents and means the importing facility must monitor foreign suppliers’ food safety plans.

Remember: Preventing pests needs to be a proactive process included in the food safety plan. If you want your supply chain to remain pest free, partner with a pest management company and talk to your supply partners to establish standards for documentation and communication. All will benefit, as you’ll be able to catch problems early and have a better chance of keeping pests from wrecking your supply chain.

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.
