Chick-fil-A sacked two of it workers after one of them was caught spitting into the batter.
The West Memphis restaurant in Tennessee was forced to apologise after a viral clip showed a worker mixing the chicken batter aggressively and then aiming their saliva into the mix.
In the repulsive video, the co-worker is behind the camera filming the disgusting action which has led to hundreds of sickened customers complaining to the fast-food joint.
Customers took to social media demanding the employees should be axed after food hygiene standards were violated.
The operator of the store issued a statement on Facebook which quickly announced both workers had been fire.
They identified the individual that spat in the batter and the worker filming the sick video.
The company said the behaviour fell well below the standards it expected, and wanted to act quickly to terminate the employees contracts.
In a statement, the company said: “We have been made aware of a video circulating on social media depicting behavior of a Team Member that is completely unacceptable.
"We have identified the Team Member, as well as the one filming, and have terminated employment effective immediately.
"We have very strict standards and high expectations for Food Safety, Team Member behavior, and our Guest Experience and this was an egregious violation of all of the above.
"You trust us to deliver you safe, fresh food with a team who genuinely cares about you. We fell short of those expectations here.
“We sincerely apologize and assure you we take matters like these very seriously and act expeditiously to address them.”
The chicken chain has previously attracted criticism after it accidentally made some of its products with an undeclared dairy allergen earlier this year.
Chick-fil-A was told by of one its suppliers that it “had unintentionally added an undeclared dairy allergen in the recipe” for its Grilled Chicken Filet and Grilled Nuggets lunch and dinner time servings.
The company was forced to update its ingredient and allergy information on its website and app.
It also had to send signs to all their fast-food restaurants to warn customers of the potential issue.
However, customers were told it was a temporary issue and said it would not happen again with the supplier.
Chick-fil-A said in a statement: “We understand and take seriously the trust our guests place in us to make sure their food is how they expect it, and we apologize for this situation.
“Our priority is that our impacted guests can enjoy these products again soon.”
The chain has over 2,600 restaurants across D.C, Washington, Canada, and Puerto Rico.
