Cleaning Up Biological Incidents is No Fun, but Preparation is Key to Protecting Everyone Involved

As I was sitting down to write the second blog for this month, I had an entirely different topic in mind, but then I received a call asking about policies and procedures for cleaning up vomit and diarrhea incidents in foodservice operations. So, much like many of your days, this blog took a 180-degree turn!

Clean-up of vomiting and diarrheal events is certainly not something that many of us think about, nor something that we particularly want to think about. However, this really is the time of year when incidents like this are more likely to happen. When it happens, we must be prepared and not scrambling for information on how to best approach the situation. The food code (section 2-501.11) notes each food establishment shall have a written procedure spelled out on how to deal with such incidents to help employees minimize the spread of contamination and limit the exposure to employees, consumers, food, and surfaces.

Often when this does occur, the pathogen we are most concerned about is Norovirus, which is the leading cause of foodborne outbreaks in the U.S., accounting for more than 50% of all gastrointestinal outbreaks. If not cleaned up appropriately not only are the employees tasked with the clean-up in danger of becoming ill, studies have also shown that Norovirus can survive up to five days at room temperature.

Effectively cleaning up such an incident is much different than our normal routine cleaning procedures. One important thing to do before the incident occurs is to put together the supplies you would need to clean-up the incident and keep your employees safe while doing so. Timely clean-up is imperative to containing the virus. While there are commercial biohazard clean-up kits on the market, they are not always the best option for everyone because you may have many of these items already available in your operation, which negates the need to buy a special kit – simply assemble everything and keep in a place where you employees have ready access to it. At the bare minimum, be sure your kit has the following:

  • Personal protective equipment:
    • Disposable gloves
    • Disposable shoe covers
    • Disposable gown
    • Disposable face mask
    • Disposable towels and cloths
    • Pair of goggles
  • Absorbent powder (such as kitty litter)

Effectively cleaning up a biological incident is much different than our normal cleaning routine…and effective preparation will keep your employees and customers as safe as possible.

Once an incident happens, make sure the employee who will handle the situation instructs all other employees and customers to vacate the area. It is important to recognize that Norovirus could spread as far as 25 feet away from what you see, so be sure to block off the area and clean and disinfect appropriately.

Be sure any employee who is handling the situation is wears the personal protective equipment outlined above and wears it properly. Next, prepare your disinfectant. Unless you are using a commercial product that notes it is effective for Norovirus, you will need to make your own bleach solution. The CDC notes that you should use a chlorine bleach solution with a concentration of 1,000 to 5,000 PPM. This means that for each gallon of water, you should use 5 to 25 tablespoons of household bleach This assumes your bleach has a concentration of 5% to 8% sodium hypochlorite. If not, check your manufacturers website for the correct concentration.

Use your absorbent powder and/or paper towels to clean-up the materials and liquid. Be sure to place the used materials into a garbage bag.

Spray the area impacted with the bleach solution. Some sources recommend laying own clean paper towels over the area and soaking with the bleach solution. The important part is to make sure the area stays wet with the solution for a minimum of five minutes. Then, clean-up the bleach solution (and paper towels, if you used them) and place into the garage bag.

At this point, it is safe to remove your disposable personal protective equipment and place in the garbage bag, then seal the bag and place it in the trash. After washing your hands and face thoroughly, be sure to rinse any of the areas impacted by the incident with hot soapy water. If you are dealing with a food contact surface, it isn’t a bad idea to use your standard sanitizing solution to re-sanitize the area and let air dry.

After the incident, be sure to also sanitize any high touch areas. Being cautious and thorough is key to protecting yourself, your employees, and your customers. Risk Nothing.

Is Implementing a Color-Coded Food Safety Plan Right for your Operation?

Foodborne pathogens are by far the most prevalent cause of foodborne illness in the United States and across the world.  There are 31 known agents that cause foodborne illnesses, and more that are unspecified or yet undiscovered – remember, E. Coli 0157:H7 wasn’t identified until the early-1980s. It is estimated each year, 48 million illnesses occur because of these known and unknown pathogens, resulting in over 3,000 deaths.

Maintaining your Equipment: Is it the Missing Ingredient in your Recipe for Food Safety?

Although I am no longer in day-to-day operations, between our students and foodservice lab at the university and my volunteer activities in my local church, I keep a close hand in food production. This past week, I had the opportunity to lead a group of men at our church in preparation of a luncheon for 100 women who were attending a spirituality retreat.  Over the course of the morning, I realized our main cooler in the kitchen was not functioning properly and was about 10˚F above the required temperature.  While we do have a commercial kitchen, we do not routinely log temperatures, so when the unit started to malfunction is questionable.  Even more concerning was not the lunch we were preparing for, but the dinner that was served the night before for 300+ families in the parish.

Contamination of Food: Chemicals, Pesticides, and more, Oh My!

If you have followed our blogs, you have often heard us opine about food safety-related behavior and communication, food traceability, and other overarching food safety topics.  We often don’t get into the weeds and discuss topics you may have learned about in your food safety training.  But I thought we might circle back around and dig into a few of these topics for a few blogs.  This month, I’d like to discuss food contamination, this blog will focus on chemical contamination of food and later this month, we will discuss physical contaminates.
