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.

Cutting Board Safety

Everyone knows to prepare food only on a clean and sanitized surface. Everyone also knows not to prepare food on a surface previously used to prepare any type of uncooked meat—cross-contamination. But does everyone know what this clean, sanitized, uncontaminated surface should be made out of? Or how cutting boards should be cared for?

A Date with Safe Food Labels

When it comes to food, calendar dates relating to time and temperature are important and sometimes confusing. Terms we use are: 1) food product or code dating used for commercial food manufacturing and 2) date marking used for food prepared onsite in a restaurant. In a restaurant at the receiving step or the retail food store as a consumer, "Sell by July 14" is a type of information you might find on a meat or poultry product. Are dates required on food products? Does it mean the product will be unsafe to use after that date? Here is some background information, which answers these and other questions about food product dating.
