Reference

Dairy farms (n=150) from 32 counties in Ohio, USA were selected from the Ohio Commercial Grade A producers listing. Farms with at least 30 cows on a farm and willing to complete a questionnaire were included. For the current study, five bovine fecal samples from each visit (for a total of 10 samples per farm) were tested for cefotaxime and ciprofloxacin resistant E. coli, except for two farms, for which samples were only available from the second visit.

Approximately 25 g of fresh fecal pats from the first 30 milking cows that were observed defecating, at the time of each visit, were collected and stored frozen.
