A mother who bought baby formula from Chemist Warehouse in Takanini allegedly found live bugs inside a newly opened tin.

A mother who bought baby formula from Chemist Warehouse in Takanini allegedly found live bugs inside a newly opened tin.

A South Auckland mother has been left “disturbed” after discovering what she believes to be live bugs inside a newly opened tin baby formula.

The Aptamil product was bought last Thursday at Chemist Warehouse’s Takanini store and carried an expiry date of June 20, 2027.

Danone, the French multinational company behind Aptamil, told the Herald it had stringent quality and safety processes in place and considered it “unlikely that an insect can remain alive in a sealed can in a low oxygen, low moisture environment”.

The company had not received any similar reports from the same batch and was investigating the complaint.

Jenny Bishop, New Zealand Food Safety’s acting deputy director general, said it was working to establish the facts but there was “no evidence, at this stage, of a wider food safety issue”.

Chemist Warehouse Takanini confirmed an internal investigation was also under way.

The mother alleged the formula tin was fully sealed when it was opened.

The mum of two, who did not want to be named, said she noticed what looked like tiny insects moving inside the powder after opening the tin on Saturday .

“You need really good eyes to spot it, like, it was, like, a really tiny one at first,” she said.

“But then when my husband dug into it, he found more.”

The tin was sealed at the time of purchase and showed no visible holes in its packaging, she claimed.

“We just went and returned it to Chemist Warehouse, and then we dug it in front of the cashiers as well.

“And then we found more inside.”

The family received a refund upon returning it to the store.

“It was a bit disturbing because, you know, we’re dealing with babies here,” she said.

“We’re presuming the whole batch might be infested, so we just switched to the other formula.”

In a statement, Danone said it takes customers’ concerns “extremely seriously” and that all batches undergo extensive testing, including for foreign matter, before being released to market.

“As soon as we were notified of this complaint, it was escalated to our quality team for further analysis.”

Danone also said scorched milk particles can occasionally appear in infant formula products.

“[They’re] a common occurrence in the milk manufacturing process and, although unsightly, they are harmless and do not pose a risk to food safety,” the company said.

“From our conversations with consumers, we know that storage conditions in the home are a critical factor for maintaining the integrity of the product once it’s opened.

“Infant formula products should be stored in a cool dry place. After opening, the container should be kept airtight; avoid leaving the tin open on counters, and consume the contents within four weeks.

“If the foil security seal is damaged or missing when opened, do not use the product.”

At this stage, Bishop said scorched particles could be a possible explanation but confirmed NZ Food Safety would independently test the product.

“We have contacted the manufacturer and will visit them and the retailers to establish the facts.”

She emphasised that if a wider issue was identified, “we would take immediate action to address the risk and keep consumers safe”.

Infant formula manufacturers were required to follow strict rules to ensure their product’s safety, with regulated environments and systematic checks at the production point, Bishop said.
