WATCH: Rat Scurries Around In Popular Long Beach Burger Chain Restaurant

A video of a rat running around in a Long Beach, California, restaurant of the food chain Original Tommy's Hamburgers has raised concerns over the food safety of the popular eatery.

The video was posted Wednesday on Facebook by Estilo Juan Estrada who alleged that he saw a rat scurrying around in the restaurant through the window when he was passing by. He claimed in his post that he "will never ever go eat there again." Estrada also asked everyone to spread the word about the incident.

The video shows a rat crawling on what seems to be the counter of the restaurant. Ironically, the rodent is seen around the certificate of the previously posted health inspection that had given the restaurant an A-rating.

The video prompted an inspection by the Long Beach Health Department Thursday. However, officials determined that there was no evidence of rodents or their droppings, said Eyewitness News.

"We sent a couple of people out there. We sent the supervisor out there and the district inspector," said Nelson Kerr, one of the officers of the health department. "We did not find an active rodent infestation at the time. There were no rodent droppings, no gnaw marks — essentially no evidence of rodents," he added.

The A-rating to the restaurant was hence not revoked and it was allowed to continue its business. "This could happen to virtually any restaurant,” Kerr told KTLA.

"Our Long Beach restaurant received the letter grade A from the local health department. On Wednesday, August 17, 2017, the health department did an inspection and did not find any evidence of infestation, therefore the restaurant still has the highest rating of letter grade A," a statement by Tommy’s corporate office said.

The authenticity of the video, which had over one million views at the time of publishing this story, was questioned in the statement released by the restaurant to Fox 11. "We are aware that someone posted a video of our Long Beach restaurant but we have no knowledge of the authenticity of the video," it said.

However, Estrada assured that the video was real. "I have no reason to lie," he told KTLA5.

Other customers of the restaurant branch said they had gotten food poisoning after eating there.

Amber Block said she was disgusted by the video when she saw it and said she had stopped eating there a long time ago. “I don't understand how people can still eat it,” Block said. “We were like, ‘never again,’” she said adding that her entire family fell sick after eating there once.

The statement by Tommy's added that a prevention company performed monthly inspections and treatment at the Long Beach restaurant and did not note any pest issues.

"Original Tommy’s Hamburgers takes great pride in maintaining a high standard of cleanliness in all our restaurants. All of our restaurants are inspected by local health departments on regular basis and have received the letter grade A, the highest rating in the industry," it read.
