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.

The Physical Elements of Food Service Hand Hygiene – Part I

September is National Food Safety Education Month and the theme has a rhyme to it – “Keep Hands Clean with Good Hygiene”. Hand washing is one of the public’s best defenses against the spread of both common and rare, even life-threatening, diseases including those caused by food, and against gastrointestinal infections caused by such organisms as the Norovirus, which plagues the cruise ship industry and food service in general.

The Incredible, Edible Egg Safety Quiz

This nutritious, delicate food is a part of many food service menus as a main course and one of the most common ingredients. The U.S. Dept. of Agriculture says Americans consume an average of 234 eggs per person per year. Eggs have also been the source of some significant foodborne outbreaks in the U.S. from one specific type of Salmonella. While eggs are an important source of protein in the diet, an estimated 1 in 20,000 eggs in the U.S. supply will contain the SE (Salmonella Enteritidis) bacteria and can cause illness if eaten raw in foods or not thoroughly cooked before consumption.

Fetching a Pail of Good, Safe Water

In the ambitious fight for food safety, don’t overlook the safety and quality of the crystal clear liquid coming out of your faucet. The United States has controls in place to ensure we have potable (safe) water that is treated and filtered to make it taste better and have no odor. Water standards and treatment are also important in food service so we don’t need a repairman twice a year to chip away the block of lime on the dishwashers heating element with a hammer and chisel in order to replace it.
