Dry Operations & Recalls

Dry operations are tricky. They are called dry operations not only because the finished product may indeed be dry, but also because water is the enemy of the products. Water creates a greater risk for the pathogen Salmonella in the environment. When I think of dry operations, I think of dry ingredients: powders, spices, gums, thickeners, vitamin and mineral blends, flour, salt, and sugar. All food companies have dry storage for these dry ingredients; I am not addressing storage here, but processing and manufacturing of these ingredients. For every dry ingredient purchased by a food facility, there is a food company making that dry ingredient.

Being from America’s Dairyland (Wisconsin), I have been in five different spray-dry facilities in the past two and a half years that were producing spray-dried milk or whey – or both. Dry. Nut roasting is dry. Peanut butter operations are dry. Chocolate – as an ingredient and chocolate manufacturing – are dry. Water is the enemy and creates an environment where the risk of Salmonella is greater.

This brings us to cleaning and sanitizing. For most of dry operations, production does not stop. (Everyone working in a wet-clean operation just gasped!) It’s true. If the equipment can keep running, it does. There may be short shutdowns for minor repairs or adjustments, but the equipment keeps running. Most of these dry-ingredient manufacturers do business on a small profit margin and can’t afford to shut down. When the equipment does go down for cleaning, it is a big deal and may take days or a week to clear the lines, make repairs, clean, sanitize, completely dry, and start back up. Most companies discard a substantial portion of the first product out in case a pathogen in the lines was cleared at start up. The cost to the company is significant.

Then there is the equipment that is never cleaned. In some operations, it is just not possible during a normal shutdown to take apart and open certain pieces of equipment for cleaning. In the event of a recall, it means that there never was truly a clean break. FDA looks to companies to inform them on when the last clean break occurred. With a clean break, a company has evidence to shorten the span of a recall back to that last clean break. This reminds me of a company I was in that had four large tanks of melted chocolates, and the different chocolates were drizzled on the top of the product. It was heaven for this chocoholic, until I learned that the large tanks were never emptied. Never. This is standard practice throughout industry. The company had a clever way of cleaning the equipment that dispensed the chocolate, but not the mother tanks. The question becomes: in the event of a recall, would the company recall all product in market with that particular chocolate?

Without a clean break, how does a company determine how far back to go for a recall? One way to determine the cut-off date is to stop production, call in a consultant to investigate, and collect hundreds of swabs for the determination of root cause. This takes time, and the company has an obligation to inform customers of the recall and may not have enough time.

My suggestion to owners of dry operations is to schedule an annual shutdown for repairs and complete cleaning and sanitizing. I know this is a huge cost. Your CFO can calculate the ultimate cost for this shutdown of production. Then calculate the cost of a recall. In addition to the cost of recalling all product from the market, what is the cost of loss of customers? This Cheesehead is going to continue to learn from clients of dry operations and formulate best practices for cleaning and sanitizing of dry operations. Please share your thoughts with me. Food safety is not competitive.

Matthew Botos, CEO of connectfood.com agrees, saying: “Dr. Knutson makes excellent points in this post. When dealing with any good manufacturing operation you must understand the hazards. This is why FSMA plans require a hazard analysis. Dry plants, as pointed out, have moisture as a concern for potential human health issues.”

Truisms About Food & Documentation

Eric F. Greenberg, a private attorney with a practice concentrated in representing FDA-regulated food companies and others.
Informational only, not legal advice

There are several truisms about food companies and documentation:

MORE DOCUMENTS THAN EVER
First, companies producing FDA-regulated foods these days are required to make and keep more documentation than ever, mostly due to the Food Safety Modernization Act of 2011. Companies are required to generate, for example, food safety plans with a hazard analysis and preventive controls, a supply chain program and a recall plan. Then, after setting up these systems, companies need to generate and keep documentation proving they are following the programs they established.
Also, companies who recall food should remember that they might have reporting obligations, within 24 hours of discovery, about food that might be a danger to health, via the Reportable Food Registry portal.

DOCUMENTS ARE NOT ENOUGH: ALSO TRAIN
Second, once you have set up those documented programs, don’t neglect to train your employees on what they require. This goes for recall plans as surely as any other aspect of your program. FDA inspectors think perty documents are fine, but they would rather see confirmation that your people have a thorough knowledge of what’s in them and operate under them all the time. Which leads to the third point…

DOCUMENTS ARE NOT ENOUGH: ALSO DO WHAT THE DOCUMENTS SAY
Third, for gosh sakes, be sure to follow your own procedures. It’s the easiest thing in the world for an FDA inspector to cite your company (that is, make an inspectional observation) for your failure to follow your own written procedures. There are a lot of interesting policy debates one could have about the wisdom or necessity of any particular detail of a company’s safety plan or preventive controls, but those debates really don’t matter if you said in your own SOP that you would check the temperature of your cake mix after baking, but didn’t do so.

DOCUMENTS AND RECALLS
Finally, documentation is relevant to recalls in at least two important senses. One is that the company will have in place the requisite recall plan, having thought through in advance the necessary steps to undertake or consider when problems arise. The value of preparing in advance cannot be underestimated, particularly because circumstances in which safety concerns arise or are suspected can be high-pressure, fluid, and even emotionally charged.
Second, of course, documentation of production can help a company identify causes or potential causes and define a limited scope for the affected product, and then identify the consignees who received the product within that scope. Without such documentation, the prospect exists that a company might decide its only reasonable option is to recall everything it’s made that is still out in commerce, which is often a very expensive and burdensome option.
