To quantify 17 toxic dioxins and furans, 3 co-planar PCBs, and16 brominated flame retardants in approximately 450 beef, pork, and siluriform samples in support of an FSIS survey of the US meat supply.
The USDA ARS will conduct dioxin analysis on approximately 450 fat, liver, and muscle samples from steer/heifer, market hog, and siluriform samples collected by the USDA FSIS for the survey. The analysis includes sample purification and quantification of 17 toxic dioxins and furans and 3 co-planar PCBs by gas chromatography-tandem mass spectrometry methods. All compounds can be isolated from a single purification procedure. The analytical method is based on EPA Method 1613 “Tetra- through octa-chlorinated dioxins and furans by isotope dilution HRGC/HRMS”. The project will follow the same Quality Assurance Project Plan (QAPP) implemented for the 2002-2003, 2007-2008, 2012-2013, and 2018-2019 surveys, with minor revisions to reflect changes in personnel and software.
