Holders of licences to keep mink are subject to conditions which include compliance with all relevant legislation concerning the environment, animal health and welfare. Licence holders are subject to regular inspection by officials from my Department to establish that they are compliant with those conditions.
Mink carcasses are generally disposed of by rendering as animal by products (ABP) at approved Category 1 rendering plants. The animals are killed humanely by gas and not by lethal injection such as barbiturates unless in exceptional circumstances they are put down by a veterinarian.
Land-spread of manure from mink farms does not present a risk with regard to the spread of any serious transmissible diseases thus manure from these farmed animals is treated the same as other manures in that it can be spread on land as fertilizer to increase the nutrient value of the soil.
Transmissible spongiform encephalopathy is extremely rare in mink. Isolated outbreaks have been reported in the USA and some Eastern European countries but no case has been reported since 1985.
