An Arby's customer in Oklahoma has claimed she contracted herpes from an employee who spat into her sandwich. 

Jennica Church, of Broken Bow, said she developed painful sores around her mouth and lips after visiting an Arby's drive-through on March 28. 

Church ordered the four-for-$10 sandwich deal from the restaurant and told KJRH that she thought the workers were upset with her because she showed up close to their closing time. 

The woman brought the sandwiches home and shared them with her father-in-law and grandmother-in-law. 

But two days after consuming the food, a painful blister formed on Church's lip, which she stated had never happened before.

She was later diagnosed by a doctor with HSV-1, commonly known as oral herpes.

Church's daughter allegedly heard from the daughter of Amanda Hendricks, former manager of the Arby's, that Amanda saw Church at Arby's and decided to spit in her sandwich. 

According to an incident report filed by local officer Zane Mann, video footage from the Arby's cameras confirmed this.

The report, seen by the Daily Mail, said: 'While making the order, Amanda can be seen grabbing meat from the slicer, bring it to around neck level, leaning her head down with her mouth close to the meat, and appears to spit and place the meat on one of the sandwiches and has the order sent out.'

The probable cause affidavit states that the video shows 'the saliva leave' Hendricks's mouth.  

After Hendricks reportedly admitted to the act in a phone call with officer Mann, a warrant for her arrest was filed and she was charged with the felony of poisoning food/medicine with intent to injure.

Along with the criminal case, Church and her family have filed a lawsuit against Hendricks claiming the incident caused anxiety, emotional distress and fear of infection, stemming from her allegedly developing herpes symptoms from the saliva.

Church said she believes visible breakouts could even impact her work as a bartender. 

'If I go out to eat and see someone with a big thing on their face, I don't want them serving me food,' she said. 

Dr Stuart Fischer, a former emergency room doctor and practicing internist, told the Daily Mail that it is possible to contract herpes from shared saliva, but it is rare.

He said: 'Usually, herpes works by direct contact. It enters the body by direct contact.

'Normal spit in a sandwich would be digested by all the body's enzymes, especially when you're eating a sandwich.' 

Fischer has treated the virus in multiple cases and mentioned that many people contract herpes without realizing as the symptoms can often lay dormant with no outbreaks. 

'It's not always active,' he said. 

In the lawsuit, the burden of proof is on Church, which in Fischer's opinion, would require that it is 'inconceivable' that she got it through other means.

'A situation like this, I've never heard of in my life, but we live in strange times,' Fischer said. 

Court records indicate that both the criminal and civil cases remain unresolved.

The Broken Bow Arby's refused to provide any comment to the Daily Mail at this time.
