Contamination of Food: Let’s Get Physical

Earlier this month, we began a discussion about contamination of food. Our first blog focused on chemical contamination, but in this blog, I’d like to look at physical contamination of food.

Any item which does not belong in the food product can be considered a physical contaminate, a hair, a piece of plastic or metal, or even a fake fingernail. While some physical contaminants, such as a piece of hair in your food may only be disgusting, other physical contaminants can cause serious injury to the consumer, including lacerations to the mouth and intestines, broken teeth, or can pose a serious choking hazard


When food arrives at your foodservice facility and throughout production, it is vital that you have strong controls in place to maintain the integrity of the food, limiting chances for inadvertent contamination of physical objects. 


Physical hazards were not something I generally had to deal with when I was in operations, I imagine the same can be said for many of you. I do recall one incident when we had a chicken salad sandwich returned by a customer, who found a red acrylic fingernail in their chicken salad.  When we surveyed the staff that day, we found that the salad, which was a prepackaged product, was opened that morning and none of our staff had on fake fingernails. Meaning the product had to come from the manufacturer.  Luckily, the acrylic fingernail only caused disgust and no serious injuries.

While food companies work exceedingly hard to keep their products free from physical contaminants, it does occasionally occur.  In 2021 and through January of 2021, 14 food recalls were issued in the United States due to foreign objects in food, including metal, plastic, glass, and small stones.

When food arrives at your foodservice facility and throughout production, it is vital that you have strong controls in place to maintain the integrity of the food, limiting chances for inadvertent contamination of physical objects.  Here are four tips to help you in achieving this goal:

  • Establish and monitor dress control policies, such as requiring employees to remove jewelry and wearing a hair restraint while in food production.
  • Practice preventative maintenance on production equipment and repair or replace damaged equipment and parts immediately.
  • Encourage employees to report any issues with equipment to supervisors and be sure to follow-through with corrective action. Not doing such will just cause employees to ask why they are reporting things when nothing ever gets fixed.
  • Work with a reputable pest control company who works with you and your employees in establishing a solid and effective pest control program.

Underpinning all of these is to be sure you create and sustain a culture of food safety throughout your organization. Managers and all staff should know that nothing is so important that it cannot be done with food safety in mind.  Check out our previous blog on developing this culture to make sure you operation is on the right path. Risk Nothing.

Sanitation, Sanitation, Where Art Thou?

Continuing the theme I picked up on a few months ago, discussing common causes of foodborne illness, I’d like to focus this blog on cross contamination, more precisely sanitation. Sanitation is another issue that employees don’t often do at home, so they discount the importance of it in the food production environment. That is to say that they have never made someone sick at home because they only clean their countertops and they have likely never sanitized their kitchen, so why is it so important in a foodservice facility?

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.
