Research at the National Animal Disease Center
The National Animal Disease Center (NADC) is the largest Federal animal
disease research center in the United States working on major diseases of
livestock and poultry. Research done here is solving major animal health and
food safety problems faced by livestock producers and the public.
For example, NADC scientists are doing research on how to stop contamination
of cattle by E. coli O157:H7, which causes severe illness and even death in
humans if they eat contaminated meat. Such research is critical for designing
and evaluating strategies aimed at reducing infection and providing a safer
product for the consumer.
For example, scientists at NADC discovered that simply adding vitamin E to
the diets of turkeys boosts their immune systems sufficiently to detect and
destroy disease-causing pathogens like listeria, effectively enhancing the
quality, safety, and shelf life of poultry meat. This, in turn, reduces the
likelihood of consumers contracting serious foodborne illness from the popular
holiday and sandwich fowl.
NADC scientists also found that moderately increasing vitamin D fed to
cattle prior to slaughter is a safe way of providing consumers with tender
beef. Raising cattle's blood calcium 20 to 30
percent by feeding the animals extra vitamin D3, beginning two to three days
before slaughter, results in an increase in muscle calcium and more tender cuts
of meat. Elevated calcium triggers the tenderizing process by activating
postmortem muscle enzymes that can help degrade structural proteins that
