In our efforts to help our customers produce the best safe, quality food that they can, we like to occasionally share resources that may be of use. Below, you will find a link discussing the Food Safety Modernization Act (FSMA) Training and Consultative Service program, (officially titled the Artisan Dairy Producer Foods Safety Initiative). In an effort to assist smaller businesses and producers, the Center for Dairy Research, Dairy Farmers of Wisconsin, and the Wisconsin Cheese Makers Association have come together to provide guidance for small businesses to meet the demands of FSMA compliance. John Lucey, from the Center for Dairy Research discusses the Initiative further here:

In recent months, it has come to our attention that there has been an increase in quality problems caused by Heterofermentative lactic bacteria that are not from starter cultures. These bacteria have been found growing on biofilms in the pasteurizer regen section of milk HTST’s, in some silage inoculants, in dairy powders and liquids used to fortify milk for cheesemaking, and on individual farms with certain cleaning issues. Once these are in the milk, they can’t be removed by pasteurization and will carry through into the cheese and whey powder by-products.
The Center for Dairy Research (CDR) in Madison has seen an increase in quality defects in cheese including off flavors such as “sour” gas formation in retail packages of cheese and cracking defects in blocks of cheese. Many companies are starting to include specifications for low spore count non-fat powders, liquid condensed skim and UF milk products, and also whey powders used in many other foods. There is also evidence of excess viscosity of buttermilk and sour cream from this contaminant.
What can the cheesemaker do to solve these issues?
- While there is no substitute for good cleaning and sanitation, there are tests available for these contaminants such as 3M’s Lactic Acid Petrifilm. Petrifilm can be used to test milk from the regen section of the HTST, screen milk loads from the farm, and test finished whey products. We have some plants already trying to locate sources of these spores by using Petrifilm.
- We have at least one DSM cheese culture being used to improve cheese flavors, especially in aged Cheddars. This culture is referred to as RF-4 from DSM. The culture is added to the cheese vat milk and competes with other contaminants to impede their multiplication and the off flavors and possibly gas that result from them.
- Eliminate biofilms in all milk handling equipment either at the plant or on the farm. We sell both 3M (LM1) and Hygiena (EnSURE & SystemSURE PLUS) ATP Luminometers that verify cleaning processes by the use of bioluminescence technology, and provide the customer with a numerical value to determine their cleaning effectiveness on food contact surfaces.
- There is some research that suggests certain silage inoculants can carry through into the milk supply. The CDR is still looking at this potential source.
- Ask for help and advice. We have a variety of industry people we can contact to visit the plants and farms to help troubleshoot.

The International Association for Food Protection (IAFP) is a member-based association of more than 4,000 food safety professionals committed to Advancing Food Safety Worldwide® by providing an international forum to exchange information on protecting the food supply.
Every year, an annual meeting is held to educate its attendees on food safety issues, and the solutions to these current and arising issues. This year, the IAFP 2018 Annual Meeting with be held at the Salt Palace Convention Center in Salt Lake City, UT.

Unfortunately there are no shortage of food recalls due to allergens. Allergens are a serious business for the food industry and, of course, for consumers. Now there is a new line of allergen tests from a company with a familiar name synonymous with food safety testing to help take on this serious concern.3M Rapid Allergen Protein Test Kits are a Lateral Flow format, that provide significant savings and peace of mind. These Allergen Kits can test finished product, and environmental verification of allergy free food contact surfaces!
What these quick tests can provide is security that one of the “Big 8” is not present when a customer is starting up production after cleaning and sanitizing. What is the “Big 8?” Allergens…Dairy, Wheat (Gluten), Eggs, Peanut, Tree Nuts, Fish, Crustacean Fish, and Soy. The only allergen that 3M does not offer in the Lateral Flow format is the Crustacean Fish allergen, but they do offer it in the ELISA format.
The 18-24 hour Rapid E.coli/Coliform Petrifilm™ Plate is another new offering from 3M that we are excited to add to our line! It is a two-in-one indicator plate for both E.coli and Coliform, which works well with a wide variety of food samples. Previously, Coliform has always been 24 hours for indication of growth, but E.coli testing took 48 hours, which reduces release of product by a full day for basic microbiological testing when using this and the Rapid Aerobic Count Petrifilm Plates.
Regarding Petrifilm, you will start to notice a new, very clean looking package on all their Petrifilm products! All the packages are a redesigned white pack with easy-to-spot color-coded labels.
Lastly, we are setting up the new offering for the 3M Molecular Detection System, which is for the detection of Campylobacter (considered one of the leading causes of bacterial gastroenteritis in humans). Infections are usually caused by consuming cross-contaminated or insufficiently processed foods (typically red meat, poultry, shellfish and unpasteurized milk).
