Memphis Dollar General worker shares videos of enormous RATS after being fired for warning customers not to buy sugar from 'infested' store: 'They're as big as puppies!'

A Memphis Dollar General worker who shared disgusting videos showing rats 'as big as puppies' scurrying around the store claims she was fired after warning customers away.

Brianna Johnson says she was let go after urging customers not to purchase sugar from the 'infested' store on Ramill Road.

She shared horrifying footage showing a huge rodent scrambling up the wall, as well as pictures showing a dead rat.

Another clip shows the floor littered with rat traps and what appears to be animal droppings.

'Seeing rats running up the wall and they look like puppies? That’s a problem,' she told FOX13 news. 'You shouldn’t do nobody like that.'

The skin-crawling footage shows a rat shooting up the electrical wiring at the back of the store before scampering into a cavity near the roof.

But she says the 'grossest' thing she saw was rats 'urinating' on sugar, something she tried to warn shoppers about.

'I yelled at her from the register, "Just go buy it from somewhere else,"' . 'They was telling me, "You can’t do that." Yes, I can. Somebody can. And I’m going to be the one that do it.'

She claimed the refrigerated food was safe, but was worried about products out back. 

'Them selling that sugar knowing the rats done urinated on it and everything? Like you shouldn’t do that,' she added.

A spokesman for Dollar General said: 'At Dollar General, the health and safety of our employees is of the highest priority, and we are committed to providing a clean and pleasant environment for employees and customers. 

'When we learn of maintenance or repair needs in or around our stores, we take prompt action to directly, or in partnership with landlord partners, address concerns in a timely manner.'

The spokesman added that the company has relationships with pest control.

They disagreed with Johnson's claims but declined to comment on personnel matters.
