Understanding PFAS and its impact on U.S. drinking water by Karl Oetjen | Blogs, Environmental / IndustrialIn recent years, per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” have become a growing topic of interest due to their persistence in the environment and potential health risks. These synthetic compounds have been widely used in various industrial applications and consumer products since the 1940s. PFAS can be found in the air, soil, and water, and studies have shown that most people have detectable levels of PFAS in their bloodstream. One of the main exposure pathways for humans is through drinking water, particularly in communities located near industrial sites, military bases, or areas where firefighting foam has been used.

The risky business of aflatoxins in milk by Robert Di Lorenzo | Blogs, Food / BeverageIf you’re in the dairy or food testing business, you know the threat aflatoxins pose. Aflatoxins are a type of mycotoxin produced by Aspergillus parasiticus, aspergillus flavus , and rarely aspergillus nomius.1 These are likely the most extensively researched group of mycotoxins because of their adverse health effects.2 What’s more, they are widely found in a variety of crops, namely maize, tree nuts, and spices. Believed to be primarily caused by rising temperatures and humidity, these naturally occurring fungi grow on crops in the field, or during storage of feed and raw materials, where they can potentially produce toxins that enter the food chain.
