Pork must be derived from production where all pigs are kept in loose housing systems during the entire breeding period. Sows may not be restrained when farrowing. In exceptional cases, if sows exhibit aggressive or abnormal behaviour that clearly puts piglets in danger, freedom of movement may be temporarily restricted with the help of a protective gate or similar for a maximum of three days. Protective gates or similar arrangements may also be used temporarily if the sow's behaviour constitutes a clear risk to the safety of the handler, or if the sow is being handled for treatment and procedures.
A pig that is especially aggressive towards other pigs may be kept temporarily on its own in a compartment where it is able to turn around without difficulty.
