Validation of aseptic fillers intended for the production of low-acid, shelf-stable products is a core requirement of the FDA’s low-acid canned food (LACF) regulations (21CFR113 and 108.35). Microbiological challenges of the aseptic zone and packaging material sterilization cycles are important components of the validation process. These challenges are often conducted at the production site using non-pathogenic surrogate organisms that mimic the resistance of the pertinent target pathogen. This presentation will provide a brief history of the use of such surrogates for the validation of low-acid aseptic fillers along with the approach we have used to qualify the surrogates as adequate for the intended technology.”

Formulating a new product can be exciting! But sometimes we are not sure of the effect this can have on growth of spoilage organisms during shelf life or risk of pathogenic bacteria. Martha Kimber from our Advance Microbiology Lab in Fresno, CA discusses this topic in this short video. Eurofins publishes our Ask an Expert Series weekly on our social media platforms.
