In Reply: In response to Dr Walker, ruminants
other than cattle may not benefit from being fed grass rather than grain prior
to slaughter. Kudva et al1 reported that
abruptly changing the feed of sheep from corn and pelleted alfalfa to grass-hay
increased their fecal shedding of E coli O157:h7,
while the opposite abrupt change from grass-hay to corn and pelleted alfalfa
decreased fecal shedding. Nonetheless, I agree that farm management practices
are an important component of a multifaceted approach to limiting Shiga toxin-mediated
illness and death.
