ANTIBIOTIC ALTERNATIVE FOR FEED
applications suitable for veterinary
administration and others where the
farmer could dose water or apply
topically - in addition to feed additive and meat treatment routes.
Regulation is a caveat to the application of bacteriophages. The FDA, for
example, has approved bacteriophages
as a food additive or food ingredient
in human food as they are generally
regarded as safe (GRAS); however, no
such legislation exists for incorporation
into animal feed or use as a veterinary
product. In Europe, any potential product would have to go down the road of
authorization for specific applications.
As such, companies looking to commercialize this technology need to be
innovative in their R&D and regulatory
Phages in the future
There is no magic bullet to replace
antibiotics. Instead a range of options
needs to be developed to suit different
health conditions, production systems
and processing requirements - and
it goes without saying that these
should always be coupled with the
highest possible standards of nutrition,
management and biosecurity.
Bacteriophages are a useful
weapon in the arsenal due to their
ability to target specific bacteria.
Scientific reviews have concluded
that bacteriophages are a costeffective alternative for the treatment
of bacterial infections in livestock.
They have great potential to deliver
safe animal food products, as well as
helping in the fight against antibiotic
resistance in humans and animals. ■
