Protecting Fresh Produce Post-Harvest, Integral to Safe Food

During the height of the summer, at least in the Midwest, farmers markets are in full swing and fresh produce is plentiful. Every backyard gardener is reaping the benefits of their work, with bountiful harvests of tomatoes and cucumbers. Everyone seems to have a neighbor who is trying to pawn off his or her over-production of cucumbers or summer squash during this time of year.  When picking up that produce at the farmer’s market or from your neighbor down the street, have you ever given any thought to the microbial safety of it?  Honestly, even in my position, it certainly is NOT the first thing that comes to my mind.  But, earlier this month, I came across a news story out of Wisconsin discussing a Salmonella outbreak associated with shelled peas sold at a local farmers market. Who would have thought shelled peas would be impacted?  The story noted, and it served as a great reminder, that most outbreaks associated with Salmonella in produce are due to mistakes made in handling or transportation of produce after harvesting.

If you are unfamiliar with Salmonella, check out a blog we did earlier this year that provided some information about the bacteria. In short, it accounts for almost a third of all food-related deaths in the United States each year, causing about 450 deaths yearly.  Mild symptoms usually include diarrhea, fever, and abdominal cramps.


…we must also realize that what we do in our own gardens or homes cannot be the same practices we employ in our operations when feeding hundreds, if not thousands of guests per day – all with different immune system and food backgrounds than our own.


Proper handling of produce is vital to ensuring Salmonella or any one of the many foodborne illnesses does not grow to a level that it will case illnesses.  First, be sure to order your produce from a reputable supplier.  Working with a local farmer is perfectly acceptable. Certainly, having the Good Agricultural Practices or Good Handling Practices designation is good, but it is not required as long as they are following those practices on the farm.

When receiving fresh produce, be sure to check for quality and freshness. While there is no temperature requirement for whole fresh produce, be sure the quality is up to your standards and, even with the current issue we are having with supply chains, don’t feel pressured to accept a lower quality product.

When storing produce, be mindful of temperature and humidity, which can both impact shelf life.  While many produce items do well at 32°F, some are cold sensitive and may require a higher temperature.  To check the optimal storage conditions for fruits, vegetables, and herbs use free online resources from reputable authors.  Our two favorite for fruits and vegetables are the fact sheets from Cornell University Cooperative Extension or the University of Maine.

I know…I know…it is fresh produce; how dangerous can it be? I am sure everyone reading this is thinking back to the time that they ate raw produce – fresh peas from the shell as you were picking them, corn off the cob as you were putting it up for the winter, or the crème de la crème for all gardeners – a fresh red, ripe tomato straight from the vine.  I must admit, I have tried all of them and didn’t even wash them before consuming, and yet I live to tell the tale.  However, we must also realize that what we do in our own gardens or homes cannot be the same practices we employ in our operations when feeding hundreds, if not thousands of guests per day – all with different immune system and food backgrounds than our own. 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.
