PORTLAND (AP) — The U.S. Attorney’s Office for Maine says a Calais man pleaded guilty to making a false statement to federal agents regarding his sale of a pesticide.

U.S. and Canadian agents asked Clyde Eldridge in 2010 to identify anyone he sold cypermethrin and whether he had records of the sales. Eldridge owned C&E Feeds, a feed and pet store in Calais. Attorneys say Eldridge told investigators that he did not keep track of the sales.

Investigators later learned Eldridge recorded sales of the pesticide to a production manager for a subsidiary of Cooke Aquaculture. That company pleaded guilty in a Canadian court to illegally using pesticides that killed hundreds of lobsters in waters near Maine’s border.

Eldridge faces up to five years in prison and a $250,000 fine.
