Objectives: Estimate the probability for hide contamination with STEC 7 among US
market (cull) beef cows at slaughter. In addition, we will test the effect of season
and geographic region on STEC 7 hide contamination at harvest.

Objectives: Test the effects of fiber concentration (NDF) or level of wet distillers
grains (WDGS) in the diet on the probability for feedlot cattle to shed STEC in
feces.
