data from various sources both domestic
and international, which indicated that data
comparisons were not comparing apples to
apples. When reading the summaries that
have been published by both domestic and
foreign organizations on antibiotic use in
food animals, the reader should be aware
of whether the reports include one or a
combination of the three antibiotic categories. For example, some reports may only
include therapeutic and preventative growth
promotants, whereas others will include
therapeutics, preventative growth promotants and ionophore coccidiostats.
ing chicken will increase because of the
decreased use of antibiotics. It might be
from a variety of causes such as increased
incidence of disease, decreased feed ef;ciency due to the omission of growth
promotants, or increased costs related to
disinfection and sanitation procedures to
reduce disease-causing organisms.
In the end, there are still situations that
will require the use of therapeutic antibiotics in poultry ;ocks that have infections.
Many companies are voluntarily removing preventative growth promotants from
diets, but the debate will continue on how
these actions will impact antibiotic use and
resistance in the future. ■
Veterinary Feed Directive
One regulatory step that is currently
being taken by the FDA (Draft Guidance
Document No. 209) to restrict antimicrobial drugs in food producing animals is
to limit their use to situations that do not
include the label for growth promotion or
performance enhancement. The new FDA
guidance will also require greater veterinary oversight. This means that anytime
antibiotics are utilized in feed, a veterinarian will have to sign authorization forms
called a Veterinary Feed Directive.
For many companies the oversight task
alone could dominate a veterinarian’s time,
reducing their time and effectiveness in
monitoring ;ock health. The FDA is aware
of this situation and is working with the
American Feed Industry Association and
the AVMA to make the VFD process more
workable while still protecting animal
health. It is believed it will also protect
humans by reducing the potential of antibiotic use in food animals, causing increased
resistance in human bacteria.

Increased poultry production
Antibiotic use in the poultry industry has
decreased over the last decade. Companies
are striving to utilize fewer antibiotics in
feeds, and they are using genetic selection,
bird management and house sanitation to
reduce the load present of disease-causing
organisms. However, even with these steps,
there are concerns that the cost of produc-
