Special Projects Track 3 Method Validation Project Summary The Indiana State Department of Health (ISDH) Microbiology Laboratory will work on and complete a method development and validation project to increase outbreak testing to include Clostridium perfringens and C. perfringens enterotoxin detection in a variety of foods. The ISDH Food Chemistry Laboratory will work to extend the LC/MS/MS method for pesticide to new matrices. Proposed matrices are fruit juices and various unvalidated baby food fruits and vegetables. The method is the AOAC 2007.01 “Pesticide Residues in Foods by Acetonitrile Extraction and Partitioning with Magnesium Sulfate”, commonly referred to as the QuEChERS extraction method. Analysis will be by LCMSMS.
