It’s trashy behavior.

The New York City Department of Sanitation is disciplining out-of-control garbage men after they were caught on video leaving one Staten Island block a trash-strewn dump.

In images posted to Facebook on July 3, workers outside a Westerleigh home on Stewart Avenue can be seen tossing trash bags into the middle of the street — where a garbage truck then runs them over, scattering refuse across the road.

It was recorded by Alessante Catalano’s household security camera at 5:27 a.m, the Staten Island Advance reported first reported.

“There’s garbage everywhere, it’s disgusting, Sanitation is supposed to clean up the place, not make it dirtier,” the outraged resident told The Post.

Catalano, 36, said sanitation workers have treated his neighborhood as a pigsty for years — carelessly tossing trash bags and pails around and leaving garbage all over the road.

He began witnessing the incidents shortly after he moved to The Forgotten Borough in 2018, but they’ve been getting worse recently.

In another stinky scene, captured on video Feb. 28, New York’s Strongest threw a garbage bag containing 20 baggies of dog feces in the middle of street. The bag broke open, the baggies fell out and cars ran them over — smearing excrement all over the road.

“The whole block smelled, it was horrible,” Catalano said.

Catalano reported the s–tshow to DSNY, which told him it investigated but found “no condition” at the location, despite the images he sent of poop-filled roads.

Sanitation workers have tossed garbage cans into his wife’s car and other cars on his block, he claimed.

“It makes me and my wife upset to see our pails thrown out in the middle of the street, I pay a lot of taxes in this city to see it go to waste is a shame,” he said.

The litter-lined streets have created unsanitary conditions, and he said it’s made it difficult to even take his dog for a walk, Catalano lamented.

“I take my dog out for a walk and she picks up trash, used paper towels I have to take out of her mouth,” he said.

“I don’t want to get anybody fired, but something has to be done.”

DSNY did not name the workers or specify how they will be disciplined for the July 3 incident.

“This video clearly does not reflect the high standards of the Department of Sanitation. Sanitation Workers are required to collect all trash properly set out for collection without leaving a mess in the streets,” a spokesperson said.
