Washington, DC—The AMI Foundation and the National Cattlemen’s Beef Association (NCBA) on behalf of America’s beef producers are collaborating on a follow-up study to an AMIF/Texas Tech University research project that found two strains of lactobacilli, bacteria commonly used to make yogurt, fed to cattle can substantially decrease the incidence of cattle shedding enteric E. coli O157:H7.
American Meat Institute’s Executive Committee
voted in January to provide funding for half of
the project’s expenses. The beef checkoff
will fund the other half.
which began in April, will aid in the
development of an effective and economically
feasible intervention strategy to reduce the
prevalence of E. coli O157:H7 in feedlot
cattle. The initial research of Texas Tech
University’s Mindy Brashears, Ph.D., revealed
that feeding cattle a diet of so called “good
bacteria” or Lactobacillus acidophilus
reduced the incidence of cattle shedding E.
coli O157:H7 by 50 percent.
follow-up study, titled “Reduction of E.
coli O157:H7 in Beef Feedlot Cattle Using
Varying Doses of a Direct-Fed Microbial,”
will evaluate the effects of three different
doses of the Lactobacilli strain NPC 747 on the
prevalence of E. coli O157:H7 in the
feces and on the hides of cattle throughout the
“This research project
marks a milestone in industry collaboration on
research to find a solution to ongoing
challenges in eliminating E. coli
O157:H7,” said AMI Foundation President Jim
Hodges. “We hope this leads to additional
collaboration on promising new
“After several years
of checkoff funded research to identify
effective technologies to address this elusive
pathogen on live animals, our beef producers
are very pleased to have the opportunity to
share in the funding of this promising
pre-harvest intervention,” said James O.

from Texas Tech University and West Texas A&M
University will conduct the study. The team
will include Brashears, Michael Galyean, Ph.D.,
Guy Loneragan, Ph.D., and Spring Younts Dahl,
Ph.D. Researchers contend that the study is
the logical and necessary progression from the
previous research and is designed to evaluate
the effects of feeding NPC 747 at lower dose
levels throughout the feeding period on the
prevalence of E. coli O157:H7.
The research aims to further optimize
this pre-harvest intervention to improve the
economic viability, while ensuring its
effectiveness on reduction of the prevalence of
E. coli O157:H7 in feedlot
AMI represents the interests of
packers and processors of beef, pork, lamb,
veal and turkey products and their suppliers
throughout North America. Together, AMI's
members produce 95 percent of the beef, pork,
lamb and veal products and 70 percent of the
turkey products in the U.S. Headquartered in
Washington, DC, the Institute provides
legislative, regulatory, public relations,
technical, scientific and educational services
to the industry. Its affiliate, the AMI
Foundation, is a separate 501(c)3 organization
that conducts research, education and
information projects for the industry.
