The New Zealand Meat Processors Association is confident the industry is doing enough to stop listeria-contaminated food from entering the market.
This follows this week's sentencing of Hawke's Bay meat processor Bay Cuisine and two employees for selling listeria-tainted meat and deleting test results showing the contamination.
Judge Bridget Mackintosh fined Bay Cuisine $130,000, while director Garth Wise was fined $32,500 and production manager Christopher Mackie was fined $30,000.
The tainted meat caused a listeria outbreak at the Hawke's Bay Hospital and was linked to two deaths.
The Ministry of Primary began investigating after listeria cases were linked to the hospital kitchen.
