Analysis of Escherichia coli O157:H7 survival in ovine or bovine manure and manure slurry
Article Abstract:
Research was conducted to examine the survival of Escherichia coli O157:H7 in the manures of cattle and sheep exposed to fluctuating environmental conditions and in experimentally inoculated manure. E. coli O157:H7 was found to survive for over one year in a nonaerated ovine manure pile exposed to environmental conditions. It survived for four months and 47 days for aerated ovine manure and bovine manure, respectively.

Effect of cattle diet on Escherichia coli O157:H7 acid resistance
Article Abstract:
The duration of shedding of Escherichia coli O157 isolates by hay-fed and grain-fed steers experimentally inoculated with E. coli O157:H7 was contrasted, including the acid resistance of the bacteria. The hay fed animals discarded E. coli O157 longer than the grain-fed animals, and irrespective of diet, these bacteria were equally acid resistant. Feeding cattle hay may increase human infections with E. coli O157:H7.

Evaluation of dietary influences on Escherichia coli O157:H7 shedding by sheep
Article Abstract:
A study was conducted on the influence of diet, fasting and other dietary changes in Escherichia coli O157:H7 shedding by sheep. Results show that sheep subjected to grass hay diet shed Escherichia coli twice as long than those fed with a mixture of corn and pelleted alfalfa. Results also demonstrate that preharvest diet control may be used to keep animals infected with the bacterium from entering the food chain.
