A dozen passengers and crew of a Delta Airlines flight reportedly needed treatment for food-related illnesses after being served spoiled food.

Delta Flight 136 was flying from Detroit to Amsterdam overnight Tuesday after leaving at around 11 p.m. It was diverted to New York several hours into the flight.

It was discovered that passengers in the main cabin of the Airbus A330 were served spoiled food. The airline says medical experts recommended the flight be diverted to New York.

The flight was over the eastern coast of northern Canada when it made a 180-turn and headed back to the United States.

The plane landed at JFK Airport in New York City at about 4 a.m. on Wednesday.

"Medical crews met the aircraft to treat any affected passengers and crew members," the airline said in a statement to HNGN. "Delta's Food Safety team has engaged our suppliers to immediately isolate the product and launch a thorough investigation into the incident."

There were 277 passengers on board the plane. Medics treated 12 passengers, the FDNY reported to the Associated Press.

The airline did not release any information about what was the bad food that was served.

"This is not the service Delta is known for and we sincerely apologize to our customers for the inconvenience and delay in their travels," the airline said.
