PROMPT ACTION
ON SULPHA SCARE
Sulphamethazine is safe, says Cyan-
amid Canada, but it's also imperative
that pork producers take strict control
measures in their herds.
A well-known antibiotic used to
control respiratory problems in both
humans and animals, sulphamethazine
was recently the centre of a controversy
at the Canada -U.S. border, where
American officials delayed a shipment
of Canadian pork to test the meat for
drug residue.
Bob Watts of Cyanamid Canada
says a recent study by the U.S. Food and
Drug Administration on sulphamethaz-
ine toxicology "does not demonstrate
any human health hazard from the con-
tinued use of sulpha products."
The study reported that high dosages
of 1,200 and 2,400 parts per million of
sulpha fed to two groups of rats for two
years resulted in thyroid tumors.
Any potential human exposure to
sulpha from its use in food animals is
"thousands of times lower than the
lowest level in the study," Watts says.
"The safety margin is enormous." The
permitted tolerance level in pork is 0.1
parts per million.
The concern over sulpha levels in
the U.S. may result in stringent testing
for residues in both domestic and im-
ported swine. But Cyanamid Canada
notes that studies done in 1980 at the
University of Guelph showed that sul-
phamethazine residues are not a prob-
lem when correct procedures are fol-
lowed. Since 1979, the company adds,
violations of sulphamethazine residue
rules have decreased significantly in
Canada.
Cyanamid Canada recommends that
producers increase their control meas-
ures by strictly observing withdrawal
periods and ensuring that no cross -con-
tamination of feeds occurs
More than 30 per cent of the pork
produced in Canada is exported to the
U.S. The Ontario Pork Producers Mar-
keting Board has set up a task force since
the incident at the border "to further
investigate and identify the problems
and aggressively educate producers and
related service industries."0
