A high-tech tracking device embedded in a slab of chocolate is among hundreds of bizarre complaints about foreign objects found in food.
Among the most unsavoury items was a condom found in a KFC meal, worms and maggots on supermarket pork and a sticking plaster on pizza.
Information obtained by the Herald on Sunday revealed 201 complaints of food safety breaches had been investigated by the Ministry of Agriculture and Forestry (MAF) since January last year.
Paragon Investigations director Ron McQuilter said the tracking device would have been highly technical and expensive because devices that tiny were difficult to find.
"Something that small isn’t normal," said McQuilter. "I’m imagining it would be very high-tech which means it will be expensive."
He suggested it could have been taken from animal researchers or made at home then placed in the chocolate to trace the woman’s movements.
"It sounds like a lunatic friend with personal issues going on as opposed to someone at Whittaker’s doing it," said McQuilter.
A KFC customer claimed to have found a condom in their quarter pack meal from Hamilton’s Frankton store in February last year, Restaurant Brands spokeswoman Jo Bell said.
As a result, KFC has installed cameras in all of its stores’ kitchens, serving and customer areas.
Food Safety New Zealand consultant Suresh Din encouraged customers to inform authorities about foreign objects in their food, poisoning or a lack of hygiene.
