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.

30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety

In January, we hit a major anniversary.  One I am betting snuck by many of you – including me! January marked 30 years since the deadly 1993 E. coli O157:H7 outbreak at Jack in the Box restaurants on the west coast. The anniversary wasn’t on any of the major news networks that I recall. It did make it into a few newspapers, at least one or two of the newspapers that are left.  It wasn’t until late-February that I realized it.

Does Temperature Really Matter when Washing your Hands?

In January, I reviewed the changes to the 2022 Food Code in my blog (check out Part I and Part II), and one change to the food code that I had mentioned, but didn’t discuss in-depth, was the change that lowered the water temperature a hand sink was required to produce to 85°F, as noted in Section 2-202.12 of the code. This requirement has been in place since the publishing of the 2001 Food Code, which required a water temperature of 100°F. Prior to this, 110°F was required (see the 1999 Food Code). So why the change and does water temperature when washing your hands really matter?

Hand sinks: Often Taken for Granted, but an Essential Part to Effective Hand Hygiene

Late in January, I received a question about hand sinks in a foodservice operation.  The question pertained to school staff (teachers and aides) who were using a hand washing sink in the school kitchen.  The question came as a matter of who was allowed access to the kitchen to use the sink, but the question itself caused me to go down a rabbit hole of requirements for hand washing sinks in foodservice operations.
