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.
Developing Good Food Safety Habits
Good habits and habit development are something that has fascinated me for several years. If you’ve attended any the training programs or presentations that my colleagues and I have conducted through our Center for Food Safety in Child Nutrition Programs, you’ve likely heard me opine about the importance of habits and how habits are created. Many times, in foodservice operations we wonder why our staff don’t follow the food safety practices we have established in our operation. Perhaps they don’t wash their hands when they are required, perhaps they just don’t use the proper method of handwashing, or perhaps we find that they don’t complete our HACCP logs as often as our program dictates should occur. And while we can stomp our feet and say “it is their job, they should just do it”, it really isn’t that simple. We can’t order people to change, although if we could, business and human resources would be so much simpler.
Getting Your Playbook for Food Safety Organized
As anyone who has ever worked in a foodservice operation knows, from the time food is received in your establishment to the time it is served to your customers, following proper food safety practices is crucial. What many don’t often think about is this time really should extend from the time the manager places their orders with their suppliers (including which purveyors you utilize), through the time the food is consumed – even if that consumption occurs off your premises and days after the original order was picked up by the guest. This is something that has certainly been highlighted by the pandemic as customers across the nation are utilizing take-out, curbside to go, and third-party delivery options more so now than ever before.
Getting Started with Building the Infrastructure
Hopefully in our first January blog, we convinced you of the importance of establishing an infrastructure within your operation to support a safe food culture. So, how does one go about doing this? Well, like any major project, break it into small bites. In our opinion, having a written guide for employees that documents expectations related to food safety basics of employee health and hygiene, temperature controls, and cleaning and sanitizing is the first step. Having this documentation serves as a reference for training and helps fulfill the mission of most foodservice operators which is to serve safe, quality food.
Food Safety Resolutions for the New Year
Finally, 2020 is in our rearview mirror and we can all turn the page to 2021! Resolutions for the new year might be more of the same from prior years (lose weight, exercise more, less screen time, etc.) OR you may have identified new practices to implement in your operation. If the latter, likely goals included some practices related to food safety – especially given the turmoil of 2020 and heightened concern by customers. It is our philosophy that attention to safe food handling practices is a win-win for any operation because of the direct relationship between food safety and food quality, which in turn leads to customer satisfaction. This past year has also demonstrated that attention to safety can affect the bottom line. Thus, the topic of our first SafeBites webinar for 2021 is on the topic of the return on investment of food safety, it is scheduled for January 20, so register now and please plan to attend.
