Project Number: 8042-32000-099-01
Start Date: Jun 15, 2013
End Date: Jun 14, 2018
Sampling will primarily be conducted on dairy farms (composite manure samples), but samples will also be collected at buying stations and slaughterhouses. Quarterly composite manure samples will be collected from 25 to 40 dairy operations. Samples will also be collected from culled dairy animals (or pens) at slaughterhouses and at facilities where animals are housed en route to the slaughterhouses (i.e. buying stations and auction houses). Samples will be cultured for the presence of E. coli and Salmonella and isolates will be tested for resistance to a panel of antibiotics.
