There are concerns a specific brand of mung beans and salad, sold in food boxes country-wide, could carry listeria bacteria.
Anyone who has bought Living Foods Ltd Spring Life mung bean sprouts, or Pams sweet mango mesclun salad should return it - the products were also in Woop and The Kai Box meals distributed across the country.
New Zealand Food Safety national manager Jenny Bishop says the products pose a serious risk.
"Listeriosis infection can be serious among vulnerable groups such as pregnant women and their unborn babies, newborn babies, people with weakened immune systems, and elderly people.
"For those in the high-risk groups, listeriosis typically has an incubation period of 2 to 3 weeks (or longer) before symptoms appear."
She says healthy adults will likely only experience mild flu-like symptoms or diarrhoea.
Even so, anyone who bought either product should throw it out, or return it for a full refund.
