The Ministry for Primary Industries is reminding people about the food safety risk of buying illegal home-kill meat.
MPI compliance officers shut down an illegal home-kill operation in Kaitaia in September, but fear this may be happening across the country.
Illegal home-kill includes meat that is bought direct from a stock owner, animals that are bought and slaughtered on site and animals that are bought and taken home for immediate slaughter.
MPI compliance operations manager Gary Orr says illegal home-kill is not inspected for disease and buyers and consumers have no guarantee it has been processed hygienically.
"When meat isn't processed hygienically and kept properly chilled there is potential for contamination and bacteria such as campylobacter, salmonella and E coli that can make people seriously sick.
