Campylobactor is the bug responsible for most cases of human food poisoning and most of those were linked to infected poultry.
But the MPI said since performance targets were introduced in 2008, setting contamination limits for poultry processors, the number of notified cases of people infected with campylobacter had halved.
There had also been a significant reduction in birds testing positive for the bacteria.
Two years ago, the Ministry introduced a campylobacter detection limit and it was now reviewing the effectiveness of that and seeking feed-back on options, which included tightening up limits.
