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.
Exclusion and Restrictions: Understanding Employee Health and the Food Code
I received a call earlier in the month from a foodservice operator who suspected that one of their employees may have fallen ill and wondered if they had to send the employee home for the day. Once I started to ask a few more questions, it became obvious that the operator wasn’t really in-tune with the food code requirements on restrictions or exclusions for employees who may not be feeling well. Given that most operations are dealing with staff shortages currently and the fact that we are about to head into the fall and winter – when we tend to see an increase in upper respiratory and other illnesses, such as the flu - it seemed like a very timely and important topic for the blog this month.
Cross Contamination and the Surfaces that go Unnoticed
In October, I ran across a new research study published in the Journal of Food Protection in early-September. The article explored cross contamination in consumer kitchens during meal preparation. One of the authors was a previous SafeBites presenter, Dr. Ellen Shumaker, at North Carolina State University. Although the setting was consumer kitchens and not the commercial kitchen many of you deal with daily, the findings were very applicable to what we often see in the foodservice setting.
Emergency Preparedness: The Not-so Calm After the Storm
If you and your foodservice operation have been hit by an emergency or other disaster, what comes next and how do you move forward? Much of the answer to this is predicated on the actual disaster that you are dealing with – a flood is certainly a much different than a fire, but some of the food safety considerations remain the same if your business has been left intact and has not been damaged by the disaster.
Emergency Preparedness and Responding to a Disaster with Food Safety in Mind
As I write the first blog this month, the realities of the devastation in Florida are coming to light as we also deal with the aftermath of Hurricane Fiona, which impacted Puerto Rico late in September. Recent news has been focused on the recovery efforts for all who have been impacted. Thus, I thought it would be fitting this month to discuss emergency disaster planning resources in our first blog and delve into recovering from a disaster in our second blog later this month.
