In Ireland, as an EU member state we have a very efficient veterinary control system. Pigs are monitored & tested on the farm.
Member states are obliged to implement a salmonella control programme at all steps along the production chain. The pork end product is exposed to a range of toxicological and other tests.
Detailed rules are in place governing acceptable and unacceptable substances that can be administered to pigs.
Antibiotics can only be used under veterinary supervision and legislation is being implemented which forbids the prophylactic use of antimicrobials.
In Ireland, a national database is being developed and it will be a requirement of the Sustainable Pig Assurance Scheme that requires producers to input on this database when the scheme is rolled out in 2019.
