A Japanese woman got more than a mouthful when she discovered fragments later identified as “dental material” in a McDonald’s hamburger, marking the fast-food chain’s latest food quality embarrassment.
The news, confirmed by McDonald’s on Friday, comes two days after the company admitted several foreign objects had been found in food at Japanese outlets, including a human tooth in a container of french fries at an outlet in Osaka.
An unidentified woman told the Asahi television network she had found three tiny fragments of what looked like teeth in a burger she bought at a McDonald’s in northern Kushiro city in September.
“I took a bite and there was a crunch,” the woman said in footage aired Friday, adding that she initially thought it was a piece of sand or stone.
“I can’t help thinking that it was (already) in the meat.”
A third-party examination determined the opaque white fragments were “dental material”, according to company spokeswoman Miwa Yamamoto, saying the substance is commonly used to fill cavities or in other dental work.
McDonald’s, however, would not confirm the woman’s claim that the fragments were inside her burger.
Yamamoto said the customer was told that there was an “extremely low chance” it could have fallen into raw material, given the highly-mechanised process.
None of the employees at the outlet had issues with their teeth at the time and the customer denied it could have come from her, Yamamoto said.
On Wednesday, McDonald’s acknowledged a human tooth had been found in fries sold by another outlet last year, while it has also been hit by incidents in which pieces of vinyl were found in chicken nuggets and a tiny piece of hard plastic in a sundae.
Japanese media reported several other cases of contamination, including a piece of metal in a pancake.
