State environmental officials said Monday they're confident air and water tests taken after a massive fire on Seaview Avenue in Bridgeport last week will come back all clear.

They say chemicals from a perfume processing plant that leaked into the Long Island Sound and other local waterways likely won't pose a threat to fish or humans.

Fire officials say investigators still haven't been able to get into the site and search for a cause, mostly because crews are still testing the environmental impact of the fire.

Gregorio Henriques, who owns H&H Shellfishing on Seaview Avenue, not too far from the factory complex, was back on the water Monday fishing for oysters and clams. He says he doesn't think the chemicals that spilled pose a threat to his business.

Aside from testing the environmental impact, officials are also trying to determine the type of chemicals used in the perfume.

The state says shellfishing is still banned in Bridgeport Harbor from Fairfield to Stratford, but fishermen are able to go farther out.
