Producers who bought the veterinary drug Penpro and didn’t receive dosage instructions should return it to the retailer.
Health Canada issued an advisory last week warning that administering the wrong dose could cause an allergic reaction or pain and irritation at the injection site.
Penpro is a non-prescription penicillin used to treat bacterial infections in cattle, sheep, hogs and horses.
Consuming meat and milk products from animals treated incorrectly is “unlikely to result in serious adverse health effects in humans,” the advisory said.
The Canadian manufacturer, Vetoquinol N.-A. Inc., has attached instructions to each new bottle of Penpro and informed retailers of the problem.
A Health Canada spokesperson said the advisory was issued as a precaution.
Consumers who require more information should contact the department at 866-225-0709.
