The Alabama chapter of a national Muslim organization is calling for an investigation and firings after it said a Decatur McDonald's put pieces of bacon in a Muslim family's McChicken sandwiches.

Khaula Hadeed, head of the Alabama chapter of the Council on American-Islamic Relations, said Tuesday that bacon was found in 14 sandwiches ordered Monday by the family at the McDonald's on 3342 Point Mallard Pkwy. SE. Islam forbids adherents from eating pork, including bacon, and Hadeed called the incident "an intentional act of religious and ethnic bigotry."

The McDonald's franchise referred AL.com to the franchisee's director of operations, who could not immediately be reached for comment.

Hadeed said the family was visiting from New York and stopped by the McDonald's after a day at the Point Mallard Water Park.

"They ordered 14 sandwiches. They started noticing it tasted different to them. They eat McChicken all the time at McDonald's. They knew what they ordered -- they know what's in the sandwich," she told AL.com.

She said a small piece of bacon was found underneath one of the sandwiches. The family then opened all the other sandwiches, which also had bacon.

"It doesn't sound like a mistake, especially on 14 sandwiches," Hadeed said.

She said CAIR-Alabama wants an investigation into the incident, including looking at the closed circuit cameras in the restaurant and kitchen. Hadeed said any staff involved should be fired.

She said an adult vomited twice after the incident.

"They're essentially disturbed about it," Hadeed said of the family.
