First it was the noise. Now it’s the smell.

Bayonne residents had another of their senses assaulted Tuesday night by a “dead carcass” odor that apparently wafted over from Newark, said officials from Bayonne and the Hudson Regional Health Commissions (HRHC).

HRHC spokeswoman Alyssa Berdnik said investigators visited Bayonne Tuesday night and confirmed the odor, but they were not able to trace it back to the source. She said the county agency received two complaints from Bayonne and two from Jersey City.

“I thought something crawled in the bushes and died,” one Bayonne resident said in a Facebook post.

Another resident said “(I) walked to (the) deli last night (and) could barely breathe, and got dizzy. (I) had to rush back home (and) shower. It was really very heavy last night.”

Berdnik said the HRHC can issue violation notices to the offending company if it is located in Hudson County. Since it is believed the odor is coming from outside the county, Berdnik said the HRHC would work with the state Department of Environmental Protection (DEP) to solve the mystery.

The DEP also received a handful of complaints, including one from Staten Island, DEP spokesman Larry Hajna said.

Last week the state Attorney General’s Office filed a lawsuit against Darling Ingredients, a firm in the Ironbound section of Newark that recycles animal byproducts and grease into materials like feed and fuel.

The lawsuit alleges Darling Ingredients is responsible for the “putrid” smell of animal carcasses.

Earlier this month loud music, also coming from Newark, was keeping Bayonne residents up at night, especially on weekends. One Facebook user asked other members of a Bayonne group if they felt like they were "in a club.”
