Positive EFSA opinion for benzoic acid
The addition of benzoic acid to pig feed does not pose
a risk on human health, according to the European food safety authority
The scientific panel of EFSA (FEEDAP) tested the feed additive
VevoVitallÂ® on the safety for the target animal, consumer, user and
the environment, and on the efficacy of the product.
Commission studied this feed additive after a request from Dutch chemical
company DSM for authorisation. The additive consists of 99.9% benzoic acid in
flaked form, to be used as a feed additive for
DSM claims that the
use of the feed additive is effective in reducing urinary pH in pigs for
fattening and subsequently reduces the production and ammonia emission to the
environment with 30%.
Two of four feeding studies conduced by EFSA
provide evidence for a significant reduction of ammonia emission at the highest
level of 10,000 mg benzoic acid kg-1 diet, the lowest level (5,000 mg) being not
effective in all studies.
Highest dose is safe
relation between urinary pH and reduced ammonia emission is not adequately
established, the FEEDAP panel cannot conclude on the efficacy of benzoic acid to
reduce the ammonia emission.
However, on the basis of two tolerance
studies the FEEDAP panel concludes that the highest dose is safe for pigs for
fattening with a narrow margin of safety (less than
