The four provisional IHSs include risk management measures based on a risk analysis on porcine reproductive and respiratory syndrome (PRRS) virus in pig meat. PRRS is a viral disease of pigs found in many pig-producing countries, but which is not found in New Zealand or Australia. The 2006 risk analysis concluded that the risk of PRRS in imported meat is non-negligible, and the following measures were recommended to manage the identified risk:
• Pig meat must be either from a country free from PRRS;
• or treated prior to import by approved cooking or pH change;
• or in the form of consumer-ready cuts.
