The diet of feedlot cattle may affect the bacterial population in the hindgut, includingE. coli O157:H7. Some research studies have shown a relationship between feeding of distillers grains and E. coli O157:H7 shedding. However, other studies do not show the same relationship. Our evaluation of research indicates feeding distillers grains is not related to 2007 ground beef recalls. Furthermore, interventions such as vaccination are more important than identifying various feedstuffs that may influence shedding.
