Learn more about the origins of the Global Seafood Alliance (GSA) and Best Aquaculture Practices (BAP) safety standards and how testing with a ISO 17025 accredited laboratory like Eurofins, can help you meet them.


Besides flavor, salt is commonly used as a preservation ingredient to bind available water and help lower the water activity. It helps create conditions that are hard for pathogens to grow in. Learn more how the addition of salt in a smoked salmon product is not very straightforward with removing pathogen risk.


Food fraud can result in serious public health consequences and damage to your brand's reputation. Learn about products at risk for food fraud and steps you can take to protect your company.


Indicator organisms are groups of microbes that are correlated with other groups. In other words, the presence of one indicates the presence of another. So, indicator testing detects a small group of pathogens instead of running over 30 tests to look for all potential harmful groups. This reduces testing times and costs.


Which food labeling rule applies to your food product? Learn more about USDA and FDA Food Labeling guidelines, coverage, and differences.


Watch this webinar to gain an understanding of the difference between the USDA and FDA labeling regulations.  Also, learn which products fall into which regulation.
