New Zealand Pork says there are still gaps in what is known about a deadly pig disease.
The High Court has rejected an attempt by the organisation to challenge Government health standards that allow limited imports of fresh uncooked pork products from countries that have porcine reproductive and respiratory syndrome, which can cause abortions and deaths among pigs.
NZPork chair Ian Carter says there is concern meat with the virus may come into the country, raising the risk of it being fed to pigs.
He says questions still need to be answered about the risks of importing affected meat.
The Ministry of Primary Industries says further conditions added to the standards make it highly unlikely the disease will enter the country.
