Raquel House said she bought the four-piece McNuggets Tuesday from the McDonald's on Cassopolis Street in Elkhart and she discovered the feather-like object when she took a bite from the second nugget, WBND-TV, South Bend, reported Thursday.
"I started to feel like there was hair in my mouth, and that's when I saw that there was white hair on my tongue; and I looked at my food, and there was feathers coming off the nugget," House said.
She said the incident has left her feeling nauseous.
"I was really upset, I mean, now I've kind of calmed down but to me this is just being a responsible citizen in our community and that's just letting people know what's going on," House said.
Harry Smith, owner of the McDonald's franchise in Elkhart, said Tuesday the matter is being investigated.
"We take matters regarding food safety and quality very seriously and caution anyone from jumping to conclusions. Upon learning about this claim, we immediately began the process of collecting the facts. Our customer's health and safety is paramount," he said.
