A United Airlines passenger who had 'biohazard diarrhea' which caused flight cancelations blamed an undercooked hamburger for the drama.

Actress Meghan Reinertsen, 29, from Atlanta, Georgia, said she spent 90 minutes locked inside the lavatory during the July 2024 flight from Newark to Indianapolis.

She went public about the ordeal via TikTok one month ago, and she gave more details during an interview with the Daily Mail on Thursday.

Reinertsen revealed that the key mistake which triggered the horrifying explosion was taking a few bites of a bloody patty, which gave her violent food poisoning.

'I had eaten part of an undercooked burger hours before I left to get back to Indiana,' she said.
