Consumption of aflatoxin-contaminated food can cause severe illness when consumed by humans or livestock. Because the mycotoxin frequently occurs in cereal grains and other agricultural crops, it is crucial to develop portable devices that be used non-destructively real-time identify materials during early stages harvesting processing. In this study, an aflatoxin detection method was developed using a compact Raman device field. Data were obtained maize samples naturally contaminated with...
Commercial animal feed in Texas was characterized by determining natural gamma emitters including 40K,137Cs, and Uranium (235U 238U) Thorium (232Th) series to obtain basic radioactivity values. The measured activity concentration of radionuclides low enough for safe consumption largely depended on the type feed.40K predominant radionuclide showing highest feed. 214 Bi 214Pb 238U decay 1.39 1.33 Bq/kg corn, respectively, lower than other types. On hand, vitamin/mineral mix samples showed...
The spectroscopic method based on surface-enhanced Raman spectroscopy (SERS) technique combined with chemometric methods was developed for simple, cost-effective, and efficient analysis of chlorpyrifos (CPF) aldicarb (ALD) pesticide residues in animal feed. Animal feeds free from the pesticides were spiked at different concentrations CPF (0-20 mg/kg) (0-100 µg/kg). Gold nanoparticles mixed sample extract SERS measurement. A significant spectral difference induced by presence level ALD...
The animal feed regulatory community utilizes analytical variations (AVs) that account for the normal variability occurs within and between laboratories. AV was created using Association of American Feed Control Officials (AAFCO) proficiency testing (PT) program results represent coefficient variation times 2 (2 CV). This study performed to assess accuracy published AVs association’s Official Publication (OP) AAFCO PT data from 2014 2020. also reevaluated current values by applying concept...
