In a statement, New Zealand Food Safety deputy director general Vincent Arbuckle said as the product was undercooked it meant bacteria, including listeria, which could cause serious illness may be present.
It was a health concern for everyone, but particularly for vulnerable groups, such as pregnant people and their unborn babies, newborns, the elderly, and those with weakened immune systems, he said.
“Affected product should not be eaten. It can be returned to the place of purchase for a refund. Should you be unable to do this, throw it out.
