Although many genera of bacteria produce lactic acid as a primary or secondary end-product of fermentation, the term Lactic Acid Bacteria (LAB) is conventionally reserved for genera in the order Lactobacillales. LAB have many applications in food production and spoilage, all of which apply when considering when and how to test for lactic acid bacteria in food.


This Eurofins SFA case study highlights their investigative capabilities and work with legal and insurance claims. Here they take you on a guided case study, where they investigate an allergen claim originating in a restaurant.

Whether it’s a finished food item or a component of pharmaceuticals, identifying suspect batches of any product is an important part of the quality control process. In this webinar, Michael Dziewatkoski of Eurofins gives you the inside look into analysis of foreign materials along with actual case studies.


In this webinar, Doug Marshall, Chief Science Officer at Eurofins Microbiology discusses an approach to zone 1 testing that recommends non-direct-contact surfaces simultaneously for pathogens and indicators, then building a correlation between quantitative indicator count and Salmonella or Listeria prevalence. Dr. Marshall will share insights on how companies are employing this approach, including exploration of the various philosophical and scientific rationales for zone 1 pathogen testing.


Not all rancidity tests are equally appropriate. Here are some helpful hints regarding how each test is performed, what it reveals, limitations and which may be more important for a given scenario.
