Evaluation Of Drug-Resistant Enterobacteriaceae In Retail Poultry And Beef, Agnes Kilonzo-Nthenge, Emily Rotich, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

There has been increasing concern on the emergence of multidrug-resistant foodborne pathogens from foods of animal origin, including poultry. The current study aimed to evaluate antibiotic-resistant Enterobacteriaceae from raw retail chicken/turkey parts (thigh, wings, breast, and ground) and beef meat (ground and chunks) in Middle Tennessee. Resistance of the collected Enterobacteriaceae to a panel of antibiotics was determined by the Kirby-Bauer disk diffusion test. Retail meats were also assayed for the presence of Salmonella spp. and Escherichia coli O157:H7. Two hundred thirty-seven samples representing 95.2% of the total of 249 samples tested were positive for Enterobacteriaceae. The level of contamination …

Certified Angus, Certified Patriot: Breeding, Bodies, And Pedigree Practices, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

The pedigree chart is a cornerstone technology for producing bodies and value in livestock pure breeding. It organizes a cluster of processes, technologies, and discourses gathered under the rubric “pedigree practices.” Angus breeders commonly use artificial insemination to import performance “genetics” into their herds, using the “expected progeny differences” predicted by massive pedigree databases that now also contain phenotype data reported by cattle growers. Discourses of biological inheritance, good breeding, and pedigrees arose in the eighteenth century, concomitant with a fascination with races, species, and other biological kinds. A case study from Angus cattle breeding illustrates pedigree practices and the …
