How Dairy Products Complicated Our 2022 Study – And What We Had To Do To Solve The Issue

When we conducted the investigation for our 2022published paper, the goal was to create a menu that was a “typical” American diet as defined by the U.S. Department of Agriculture. That “typical” diet demanded that we include cow’s milk. And that was a problem. Dairy has many opportunities for plastic contamination For dairy products, we […]

To avoid possible plastic contamination in the milk samples we sent for Mass Spec testing, we used glass bottles and aluminum foil to prevent sample contact with the plastic cap. This technique also works well in the kitchen when glass storage containers have plastic lids. This ad-free article is made possible by the financial support […]
