New Zealand Food Safety is urging locals, specially pregnant women and those over 65, to take extra care with what they eat, following seven tragic deaths from listeriosis last year.

The disease, caused by the bacteria Listeria monocytogenes, is rare but can be deadly.

It’s often found in ready-to-eat refrigerated foods and, worryingly, can grow even when chilled.

That makes it a sneaky risk for many Coasties who assume the fridge keeps things safe.

Vincent Arbuckle, deputy director-general at New Zealand Food Safety, says, “While rare, every year people die from listeriosis – and the effects are tragic for their families.”

Forty people were hospitalised in 2023 alone.

While healthy adults usually recover quickly, the infection can lead to miscarriage, premature labour or stillbirth during pregnancy.

And as we age, our immune systems naturally weaken, making everyday foods riskier.

Among the higher-risk items?

Deli meats, smoked seafood, soft cheeses like brie and camembert, unwashed leafy greens, raw sprouts, and even soft-serve ice cream.

The list includes foods often found at local cafés, weekend markets, or tucked into a Coastie picnic hamper.

To stay safe, the advice is simple but serious:

• Thoroughly wash and dry fruit and veg
• Reheat leftovers until they’re steaming (over 70°C)
• Cook frozen vegetables properly
• Avoid long-shelf-life chilled items unless reheated
• Choose freshly prepared food
• Practise good hygiene—wash and dry hands thoroughly

It’s a timely reminder, especially as World Food Safety Day was marked on Saturday, 7 June.

This year’s theme, Science in Action, highlights how scientific research underpins everything from public guidance to rules for food producers.

Listeria doesn’t spread person-to-person—it’s picked up from contaminated food. So local awareness really matters.

Whether you’re preparing lunch for your grandkids in Gulf Harbour or stocking the fridge in Waitoki, a few smart food choices can make all the difference.

New Zealand Food Safety is also encouraging people who care for at-risk groups to sign up for recall alerts and help spread the word.

Because when it comes to something this serious, a little knowledge can save lives.
