Dangerous debris washes ashore before beachgoer makes another troubling find

Officials at the New Jersey Department of Environmental Protection (NJDEP) said the debris included household waste, including syringes used for at-home insulin injections, according to local outlets.

Mayor Michael Mangan told Fox News Digital the syringes were first discovered Saturday afternoon and were cleaned up and properly cleared away. 

"There was a large amount of additional debris, indicating a garbage spill of some kind, and the incident was localized to the south end beach, along the Manasquan Inlet jetty," Mangan said.

Mangan added that, in accordance with guidance from the NJDEP and Monmouth County health officials, the town waited for two high-tide cycles, which occurred overnight Saturday.

By 9 a.m. Sunday, state and local officials "met on site, and no syringes were observed - so the water was reopened," Mangan told Fox News Digital.

But not all residents agreed with the timing of reopening the waters.

Priscilla Mahajan, a Manasquan resident, told local outlet News 12 she found needle plungers and drug paraphernalia on Sunday.

Mahajan had participated in the cleanup efforts the day before. She said she felt the beach reopened too soon.

"One beach cleanup is definitely not enough to say something is safe," the resident said.

Mahajan told CBS News she found syringes, cut straws, syringe plungers, syringe caps and small plastic baggies along the beach.

Fox News Digital reached out to the NJDEP, but the agency declined to comment.

At the time, shark ecologist Mike Heithaus told Fox News Digital that seeing so many sharks wash ashore at one time was rare.

The incident did not appear consistent with a widespread toxin or pollution event, Heithaus said, and he suggested the sharks may have been caught and discarded.
