Hobson's brand sandwich ham sold in the North Island are being recalled due to possible presence of Listeria.
The ham was sold at Gilmours Manukau, Tauranga, Hamilton, Palmerston North and Wellington.
New Zealand Food Safety says a batch number of 1SA4 and a best before date of March 3 2023 is affected by this recall.
It can be returned for a refund.
Listeria is a foodborne bacterium that can make people sick and this product should not be eaten.
Listeriosis infection can be serious among vulnerable groups, such as pregnant people and their unborn babies, newborns, the elderly, and those with weakened immune systems.
It is particularly dangerous during pregnancy as it can cause miscarriage, premature labour or stillbirth, and infection in the unborn baby.
Infection in healthy adults is unlikely to be severe, causing mild diarrhoea and flu-like symptoms.
