The recall of cheeses due to the presence of Listeria monocytogenes in Deutsch Käse Haus caused a snowball effect since Deutsch Käse Haus is a business–to-business provider of cheeses.

Once a food recall is issued, each company that receives the contaminated products has to look at how contamination may have spread through its own plant. The situation becomes more complicated as supply chains grow longer and longer. The globalization of food supply chains makes widespread outbreaks more likely, and in some ways more difficult to track.

It is hoped that the new FDA regulation as shown in the draft “Control of Listeria monocytogenes in Ready-To-Eat Foods” will eliminate the repeat of the ripple effect of recalls.

How Deutsch Käse Haus Started the Snowball

On January 30 the Tennessee Department of Agriculture took a sample of the Amish Classic Colby from a store in Trenton, TN, and found it to be contaminated with Listeria monocytogenes (LM). By February 9, they posted an alert announcing a recall of Amish Classic cheeses and Meijer branded cheeses, all made by Deutsch Käse Haus, a company owned by Michigan Milk Producers association since fall 2016.

Since Deutsch Käse Haus is a business–to-business provider, a number of their customers were required to recall their products. The customers of these customers had again to notify their customers, resulting in a snowball effect.

The voluntary recall covered products made at Deutsch Käse Haus factory between September 1, 2016 and January 27, 2017. All the recalled products were produced by Deutsch Käse Haus. Meanwhile, all production has been suspended at the LaGrange County plant while the Food and Drug Administration (FDA) officials investigate the cause of the contamination.

The Snowball Effect

How does Listeria Enter the Products?

Listeria Monocytogenes is present all around us, mainly on dust on the ground. Once Listeria enters into a manufacturing facility it is difficult to get rid of it. The primary reason for it is that LM tolerates salty environments and cold temperatures and can even continue to grow at temperatures as low as -5˚C. It is difficult to eliminate it; therefore the focus must be on prevention.

Contaminated boots can allow Listeria to enter the plans. Drains can harbor Listeria and must be properly maintained.  It is important to keep the factory floors dry at all times, since Listeria like most other bacteria needs water to grow.

In the FDA  Draft Guidance for Industry: “Control of Listeria monocytogenes in Ready-To-Eat Foods” there are detailed recommendations on how to control Listeria. The FDA encourages a “seek and destroy” approach.

FDA new rules RTE products- Listeria

For the first time, FDA has a legislative mandate that will require comprehensive prevention-based controls across the food supply to prevent or significantly minimize the likelihood of problems related to LM.

Facilities have “one free pass” of detecting Listeria in the environment and continue production, without a need to stop production. The finding still requires the performance of root cause analysis, extensive cleaning, sanitation, retesting, and investigation.

In the draft, there is a differentiation between low risk (do not support more than 1 log of growth) and high risk products. This differentiation affects the monitoring regiment as well as corrective action that need to be taken.  The guidance discusses product formulating as a mean to control of Listeria. The formulation must limit the growth of Listeria to less than one log. To be considered Listeria reduction a process must reduce it by 5 logs.

There are instructions on how to develop a robust environmental, sanitation and supplier verification programs. The goal is to find Listeria and eliminating the source of contamination. There is an emphasis on record keeping. There is a lengthy discussion on corrective actions should an environmental sample be found positive.

If LM is detected on Food Contact Surfaces (FCS), the food should be reprocessed, diverted or destroyed. The firm should consider a recall.

The guidance includes recommendations for controls involving personnel, cleaning and maintenance of equipment, and sanitation, as well as for treatments that kill Listeria monocytogenes and formulations to prevent it from growing during storage of the food between production and consumption.
