How Do We Know Our Food Supply is Safe?

By Jack Etzel


There’s a clear commonality among human beings that no one can deny; we all have to eat. So before we eat up, let’s read up so that we might become smarter about how to avoid getting ill (or worse) from what we’re putting into our mouths.

For the past 22 years, John Stella has been the state’s food safety supervisor for a 10-county region of southwestern Pennsylvania. He was born into a family poultry farming operation and later became a biologist, and has served as a food safety expert in municipal and private industry. For the past 30 years, he has been employed by the Pennsylvania Department of Agriculture (PDA), where he works from an office in Gibsonia.

North Hills Monthly Magazine (NHMM): It would seem that most of us should be more aware of food safety today than, say, a generation ago. How true is that?

John Stella: When it comes to food safety, it’s a matter of being educated so you know what issues to look for. As regulators, we know that the biggest abuses of food safety happen in the home. We even know that one big reason for that is because when they cook, most people keep repeating methods and ways of doing things in the same way that they were taught, or doing what they were exposed to for generations.

NHMM: Can you give us an example?

Stella: Oh, putting frozen food out on the counter to thaw, instead of making use of the proper temperatures to defrost items. That’s just one example of simply not knowing the risks and dangers associated with thawing food the wrong way. In the food industry, when we do inspections we ask store employees why they do certain things, and they often say that they were taught to do it that way. Employees sometimes don’t understand why they have to do things in a certain way to best protect the food supply.

NHMM: Since we started this by mentioning temperatures, I would guess that quite a few people at home don’t even own, much less use, thermometers in their refrigerators or freezers.

Stella: And you’re talking about a piece of equipment that most home cooks were never taught to use, despite the importance of a thermometer. A residential refrigerator is not made to be opened and closed frequently. Those compressors can’t recover quickly enough, and often the food inside is thought to be just fine between 40 and 45 degrees, even if they have a thermometer in the refrigerator. In the food industry, refrigerated food must be kept at 41 degrees or less, and that would be a very good standard in your own home as well. The rule of thumb is ‘the closer to freezing, the better.’ Considering the small amount that a refrigerator thermometer costs, it could be a valuable investment. Everyone should also own and use a meat thermometer, too. People still prepare meat by sight or touch.

NHMM: For anyone who bothers to read labels in stores, the globalization of our food supply is obvious. Is expanding importation a concern to you?

Stella: It is a concern. The Food and Drug Administration (FDA) checks the ports for imported products, but there’s a fallacy or misconception that a large portion of these foods are checked at the ports. The truth is, it’s likely that less than 1 percent is actually checked. Only within the last five or six years have we been sending our investigators to other countries to check on their processing methods. That check is designed to cut down on shortcuts that might be taking place and it’s important. Meanwhile, on the national level, it’s the United States Department of Agriculture (USDA) that regulates meat, poultry and egg products.

NHMM: Whether a person is in the kitchen or at the store, what advice would you offer?

Stella: You mentioned labels. Read the labels and directions on everything. What temperature should be used for cooking something? Should it be kept frozen? Look at the expiration dates on every purchase and respect them.

I also think that anyone today who works in a kitchen should go on the Internet to research the subject. It’s easy to gain very important knowledge on food safety that didn’t exist a generation ago. Just do a Google search by putting in the words ‘food safety.’ You’ll learn new facts that you never knew. You don’t have to become versed on the professional level of food safety, but read articles that spell out basic concepts. That would include proper temperatures for storage; proper temperatures for cooking a variety of foods; the risks associated with particular foods; the risks of cross contamination in the kitchen; and even discussions on related subjects, such as allergies.

NHMM: Allergies? I never imagined that your position as a food safety supervisor included such things as allergies.

Stella: We often get complaints from people who thought that there was something wrong with their food, only to find out after the fact that they either have a food allergy or food sensitivity, or that as they aged, they might have developed one. As we age, that can and does happen.

NHMM: Your bottom line?

Stella: Consumers should know that our food supply is safer than it’s ever been. Ever expanding knowledge and expanding technology means that we’re getting better at what we’re doing. On the other hand, we’re never satisfied.
