Photo of Delta’s ‘Spoiled’ Meals That Were Served to Passengers Reveals Mold on Food: ‘Tasted Really Sour’

Meal service was adjusted on “a few dozen flights” in the days after the July 3 incident, a Delta spokesperson confirmed to PEOPLE

Delta passengers are opening up about being served spoiled meals on a recent flight from Detroit to Amsterdam.

PEOPLE previously reported that Delta Flight 136 was diverted to New York City’s John F. Kennedy Airport on Wednesday, July 3 after passengers were served contaminated food and needed medical attention.

One traveler said the whole experience “wasn’t good” while describing the incident to CBS News on July 4.

“There was these two black spots that almost looked like burnt cheese,” they told the outlet. “I thought it was just something different, and I guess that turned out to be the black mold.”

Another recalled, “One girl said that she did eat the chicken and she didn’t finish it because it tasted really really sour.”

Photos of the meals show spots of mold growing on multiple meal packages. Some of the moldy areas appear to be significantly larger than others.

A Delta spokesperson confirmed to PEOPLE that meal service was adjusted on “a few dozen flights” in the days after the incident so the airline could “work with catering on reviewing quality assurance of meals.”

As of Friday, July 5, the airline is “ramping up to our full, everyday service,” the spokesperson added.

While no one was hospitalized, at least 12 passengers were treated by paramedics, the spokesperson confirmed to PEOPLE.
