Why Canning in Foodservice Really Isn’t a Good Way to Preserve Fresh Produce
Canning has long been a trusted method for preserving fresh produce, offering a way to extend shelf life and minimize waste. I grew up canning garden produce at home with my family and to do this day, I still can salsas, meat broths, pickles, and other tomato products for home use. In fact, it is a hobby of mine that I enjoy undertaking – much to the chagrin of my wife who simply tolerates my obsession to find new, interesting, and safe canning recipes.
Canning has had a resurgence of sorts in the past few years. Thousands of videos online address the topic and fueled by the supply chain disruptions and rising food prices we’ve seen since the pandemic in 2020, canning has become a popular activity once again. Home canning is a great activity – it allows individuals to preserve the produce they grow or buy locally, reduces dependence on store-bought goods, gives you greater control over your food supply and what goes into it, and fosters a sense of independence and preparedness.
That said, home canning should stay just that way – in the home. In a foodservice environment, we’ve seen increased interest in this among chefs and managers as they look to make use of farm-to-table or farm-to-school programs. While it may be ideal for home operations, canning fresh produce in a foodservice setting is often impractical and can lead to inefficiencies and safety risks.
Canning is very labor-intensive, requiring multiple steps. Once you have the produce in the operation, you must wash it, process it, sterilize your jars, prepare the product, fill the jars, and then finally process. Then, once you finish processing you realize that some of your jars didn’t seal, and all that work was for naught! In a foodservice environment where efficiency is paramount, dedicating staff hours to such a tedious process can disrupt operations. Instead of focusing on food preparation and service, staff would be tied up with canning, reducing overall productivity and profitability.
Most importantly, canning carries inherent food safety risks. Improper canning can lead to botulism, a serious and potentially fatal illness caused by the bacterium Clostridium botulinum. Even a small amount of botulinum toxin can make someone ill because the toxin is so potent. Ensuring safe canning practices requires rigorous adherence to tested methods, proper acidity levels, and precise processing times. There’s little room for error, and the stakes are too high if safety protocols are compromised.
From a regulatory standpoint, home canned foods are not allowed in school meal programs per USDA FNS guidelines. If you are another retail foodservice operation, you can only partake in this type of food preservation methods with the approval of your regulatory authority. At the very least, the FDA model food code would require that you have a fully functional HACCP plan in place to receive a variance to engage in this method of food preservation.
In closing, I am a big proponent of home canned food and encourage everyone to try it at least once…at home being the key phrase. But it is a different story in a foodservice operation where you are serving hundreds, if not thousands of guests daily. Hopefully, this discussion will quell your desire to implement canning in your foodservice operation. While canning may seem like a great marketing ploy and a way to preserve fresh produce, it is far from ideal in the foodservice industry. The time, labor, and safety risks associated with canning far outweigh its benefits for a commercial operation. Risk Nothing.
Call out: Most importantly, canning carries inherent food safety risks…there’s little room for error, and the stakes are too high if safety protocols are compromised.
September is Food Safety Education Month: The Culture of Food Safety
Developing a culture of food safety is important for any foodservice operation. You may be wondering--just what is a culture of food safety? Let’s start talking about it by first defining what is meant by culture. When you look culture up in the dictionary, you will see terms such as shared knowledge, beliefs, values, attitudes, and meanings; a way of life; patterns of behavior; learned behavior of a group of people; and transmitted from generation to generation. I think these descriptors provide good insight into the meaning of a culture of food safety. You can also think about where you grew up, and a vision of culture comes. For example, I grew up in rural Oklahoma, graduating in the 1970’s with a class of 24 students. My culture instilled in me an appreciation for rural life, hard work, and independence. As I grow older, I realize I haven’t changed very much from my early years, even though I have completed a PhD, lived a lot of places, and traveled throughout the world!
Produce Safety: Special Considerations
In our last blog, I talked about general produce safety. Today, I want to talk about some special products—melons, tomatoes, leafy greens, and sprouts. These are all foods that have a history of bacterial contamination leading to foodborne illness. I also want to discuss salad bars because they have some special risks.
Fresh and Tasty Produce, but are there Food Safety Concerns?
One of the best things about the middle of summer is the wonderful variety of tasty fresh produce that is available. I hope you are enjoying the fruits of the harvest because it has great flavor and provides us with a variety of important vitamins, minerals, and fiber needed to maintain good health.
SafeBites Time and Temperature Control: How To’s
Welcome back! In the last blog I gave the low down on temperature controlled for safety (TCS) foods and the temperature danger zone (TDZ). The focus of this blog is all about control of time and temperatures of foods in your operations. You might say we are discussing Control Issues! Kidding aside, knowing that temperature abuse is a leading cause of foodborne illness, it only makes sense to pay attention to the time that TCS foods are in the TDZ (remember, that is between 41° F and 135° F). FoodHandler® recently updated some useful time and temperature documentation tools.
