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.
Chemical contamination of food isn’t something we hear about in the food service world very often. Perhaps it isn’t even something you have given much thought to since you completed your last food safety class and exam. Yet, each day in our operations we have thousands of opportunities where food could become contaminated. While you certainly could have an instance where someone intentionally contaminates food (which is why we should have a solid food defense plan to try to mitigate the likelihood of this occurring), when I discuss these types of contamination, I am approaching them with the assumption that it would happen inadvertently.
While you may not see many foodborne disease outbreaks due to chemical contamination, it does occur. In the late 1990s, there was an outbreak in California where 107 individuals fell ill due to consuming food seasoned with salt that was contaminated with methomyl, another suspected incident occurred in 2020 in Washington State where individuals fell ill due to nitro cold brew coffee that contained traces of a cleaning agent. In my own experience, I remember a customer one time helping himself to a coffee refill at the end of an evening and pouring himself a nice coffee cup full of urn cleaner, while he took a drink of it, luckily, he spit it out quickly upon realizing it was not coffee.
Yet, each day in our operations we have thousands of opportunities where food could become contaminated with a chemical…
There are certainly several different reasons why food can become contained by chemicals in our operations. Perhaps we have a malfunctioning dishwasher that is adding too much detergent or sanitizer to the cycle and thus the machine is unable to remove all traces of the chemical, perhaps we don’t effectively wash fruits and vegetables that are brought in as part of our farm-to-table operation, an employee unknowingly splashes a chemical or pesticide onto nearby food that will be served to a guest, or a production employee who unknowingly stores a tomato-based sauce in a galvanized metal container. Whatever the reason, we should have a plan in place to protect our guests from food that has been contaminated with chemicals.
I know that many of your operations likely have these standard operating procedures in place, but now is a good time of year to do a spot check to make sure your employees are following the policies and procedures you have outlined for them. Here are a few to check on:
- Store and label all chemicals separately from food;
- Make sure your employees (even those who are part-time teenage staff) know how and when to use the chemicals you have in-house. More is not always better in most instances;
- Read and follow all manufacturer recommendations and instructions related to the use of cleaning or pest-control products; and
- Make sure all production and storage equipment and approved for their intended use in the operation.
Last, but certainly not least, ensure all employees are knowledge about food safety and that you meet the requirements for food safety training in your jurisdiction. Sorry if we sound like a broken record on the training issue, but employees can’t practice something which they have never been trained about.
If you haven’t watched our first SafeBites Webinar of 2022 yet, be sure to check it out! We are changing things up this year and all our SafeBites webinars will be offered on-demand at whatever time is most convenient to you. The first webinar, Getting the Word Out: Communicating Your Organization’s Food Safety Practices, presented by Dr. Catherine Strohbehn, is posted and ready for you to watch. Be sure to reach out if you have any questions about food safety or have a topic you’d like to learn about in an upcoming SafeBites Webinar. Until then, Risk Nothing.
Developing Good Food Safety Habits
Good habits and habit development are something that has fascinated me for several years. If you’ve attended any the training programs or presentations that my colleagues and I have conducted through our Center for Food Safety in Child Nutrition Programs, you’ve likely heard me opine about the importance of habits and how habits are created. Many times, in foodservice operations we wonder why our staff don’t follow the food safety practices we have established in our operation. Perhaps they don’t wash their hands when they are required, perhaps they just don’t use the proper method of handwashing, or perhaps we find that they don’t complete our HACCP logs as often as our program dictates should occur. And while we can stomp our feet and say “it is their job, they should just do it”, it really isn’t that simple. We can’t order people to change, although if we could, business and human resources would be so much simpler.
Getting Your Playbook for Food Safety Organized
As anyone who has ever worked in a foodservice operation knows, from the time food is received in your establishment to the time it is served to your customers, following proper food safety practices is crucial. What many don’t often think about is this time really should extend from the time the manager places their orders with their suppliers (including which purveyors you utilize), through the time the food is consumed – even if that consumption occurs off your premises and days after the original order was picked up by the guest. This is something that has certainly been highlighted by the pandemic as customers across the nation are utilizing take-out, curbside to go, and third-party delivery options more so now than ever before.
Getting Started with Building the Infrastructure
Hopefully in our first January blog, we convinced you of the importance of establishing an infrastructure within your operation to support a safe food culture. So, how does one go about doing this? Well, like any major project, break it into small bites. In our opinion, having a written guide for employees that documents expectations related to food safety basics of employee health and hygiene, temperature controls, and cleaning and sanitizing is the first step. Having this documentation serves as a reference for training and helps fulfill the mission of most foodservice operators which is to serve safe, quality food.
Food Safety Resolutions for the New Year
Finally, 2020 is in our rearview mirror and we can all turn the page to 2021! Resolutions for the new year might be more of the same from prior years (lose weight, exercise more, less screen time, etc.) OR you may have identified new practices to implement in your operation. If the latter, likely goals included some practices related to food safety – especially given the turmoil of 2020 and heightened concern by customers. It is our philosophy that attention to safe food handling practices is a win-win for any operation because of the direct relationship between food safety and food quality, which in turn leads to customer satisfaction. This past year has also demonstrated that attention to safety can affect the bottom line. Thus, the topic of our first SafeBites webinar for 2021 is on the topic of the return on investment of food safety, it is scheduled for January 20, so register now and please plan to attend.
