A Houston man is suing fast food chain Whataburger, claiming he suffered an allergic reaction to onions on a burger – despite ordering the meal with no onions.

Demery Ardell Wilson says he had such a bad allergic reaction to the onions while dining at one of the restaurant’s chains on June 24 that he had to seek medical attention.

Wilson claims he took one bite of his meal and immediately tasted onion – which was enough to cause an allergic reaction, according to a lawsuit filed in Harris County, Texas.

He filed a lawsuit against Whataburger on April 25, seeking “monetary relief over $250,000 but less than $1,000,000,” after asking for a meal with no onions, the court filing states.

In the petition, Wilson says he suffered “serious personal injuries” as a result of the incident and was forced to “seek the care of medical professionals.”

Wilson also claims the restaurant was negligent in serving him in the suit. It was not immediately clear which branch of the chain he had visited, or what he ordered.

Meanwhile, Whataburger is pushing back against Wilson’s allegations, requesting “strict proof” while denying his claims in a separate court document filed on May 16.

Whataburger declined to comment when reached by The Independent.

Wilson has previously sued a fast food chain over being served onions against his request.

He filed a lawsuit against Sonic Drive-in last year, claiming a meal he ordered without onions also triggered an allergic reaction.

Earlier last week, Sonic requested that Wilson be required to prove the allegations against them and requested a jury trial, Fox 13 reported.
