CHEMISTRY ABSTRACT The Agricultural Chemistry Laboratory proposes four sub-projects under the chemistry discipline for analytical track 3. These sub-projects combined, comprise the analyses of 500 samples to improve animal food testing surveillance through the chemical analysis of animal food products. The test results generated by the proposed projects can be used to remove adulterated animal food from commerce and aide regulatory inspection programs in conducting investigations. Under chemistry analytical track 3: animal food product testing, the chemical residue section of the Laboratory plans to assess 250 cat and dog food samples for aflatoxin residues by traditional HPLC technology as well as screen these same samples by using and automated ELISA technology for aflatoxin as well as 5 additional mycotoxins. The microbiology section of the Laboratory plans to assess 100 feed samples labeled for swine, equine, and other sensitive species for fumonisin and deoxynivalenol residues using traditional ELISA as well as automated ELISA technology. The inorganic section of the Laboratory plans to assess 100 nonspecific animal feed and pet food samples for the presence of toxic metals using ICP-OES as well as thermal decomposition, amalgamation, and AAS technology. Additionally, the chemical residue section of the laboratory plans to assess 50 pet food samples for cannabis, hemp, and CBD/THC using UPLC technology.
