Low water activity foods (LWAFs) have historically been considered low-risk for microbiological hazards because their limited “free” (unbound) water in the formulation prevents bacterial growth. However, foodborne illness outbreaks revealed that pathogens can survive for extended periods in LWAFs, even in the absence of growth. Watch now to learn what is required to validate control measures to reduce microbial risks in LWAFs. Originally Aired on June 18, 2025.
The Eurofins team of process authorities routinely provides expert guidance to food manufacturers to prepare microbiologically safe products. In this service, we encounter many questions that span across a variety of food products and manufacturing processes. Here we list and will continue to compile the most common questions and answers asked of a process authority and the responses. Use this information as a guide in your scheduled process or as you work through the formulation and development of your new food product. You may also use this as a tool to submit your own questions for a process authority!
When it comes to food safety and regulatory compliance, acidified foods stand out as a unique category that demands careful attention. These shelf-stable products, ranging from pickled vegetables to tangy condiments, rely on precise pH control and proper processing to ensure they remain safe and stable for consumers. In this webinar, we’ll simplify the complexities of acid and acidified foods, breaking down key factors regarding microbiological safety, stability, and regulatory compliance.
The demand for low- and non-alcoholic beverages is booming, driven by evolving consumer preferences for healthier, more mindful drinking options. But behind this innovation lies a complex challenge: without alcohol’s natural antimicrobial properties, these beverages face a higher risk of spoilage and contamination. Ensuring product safety, shelf stability, and regulatory compliance requires more than careful brewing—it calls for the expertise of a qualified process authority. Here is a look at the key risks, essential testing protocols, and proven strategies to keep your low- and no-alcohol products safe, high-quality, and market-ready.
Here we highlight the best practices in process validation that pet food manufacturers may use to scientifically demonstrate that a given process, or “kill step,” in the manufacture of pet food and pet food products can deliver the required microbial reductions to ensure the safety of their product.
Understand what an acidified food is, the regulations associated with acidified foods, and different sterilization techniques (thermal processing and cold-fill-hold) for various food products. This guide will help you to determine the classification of a food, and provide resources to aid in processing, FDA filing, and where to go to with further questions.
The effectiveness of a preservative or antimicrobial product is critical in ensuring the safety of a food product and extending its shelf life. This article helps you to understand the basic considerations of preservative and antimicrobial efficacy testing, including determining a minimum inhibitory concentration (MIC), giving you the background needed to select the best test methods for your food product evaluation.
This poster evaluates the microbiological safety of immersion method concentrated coffee, and single strength cold brew coffee processed by UHT. The results were used to determine if temperature controls for safety (TCS) should be required for these products during retail.
