The FDA’s Food Safety Modernization Act (FSMA), requires domestic and foreign food facilities registered with section 415 of the Food, Drug, & Cosmetic (FD&C) Act to enact risk-based preventive controls. This document provides information on the required analysis of hazards and risk-based preventive controls to minimize or prevent identified hazards.


The dietary supplement industry has become an increasingly regulated industry since the introduction of the dietary supplement GMPs in 2007. There is still to this day an industry confusion as to the requirements needed to comply with the dietary supplement GMP requirement to use a scientifically valid method. So does this mean the method must be validated?


As NIR instrumentation ages or manufacturers discontinue the support for older platforms, it is necessary to look for a replacement. With so many brands and models in the market and manufacturers’ claims of impressive capabilities, how does one narrow down the selection and find the correct choice?


In this article read about how Eurofins QTA has developed a new method using NIR to test the THC levels of hemp and cannabis that are being utilized by state police to rapidly determine the THC levels of confiscated cannabis.
