A jury awarded $3.3 million to six workers who claimed they were left sterile by a pesticide used at a banana plantation in Nicaragua operated by Dole Fresh Fruit Co. The workers' lawsuit accused Dole and Standard Fruit Co., now part of Dole, of negligence and fraudulent concealment while using the pesticide DBCP in the 1970s…The suit also alleged that Dow Chemical Co. and Amvac Chemical Corp., manufacturers of the pesticide, knew it could leave workers sterile and kept that information secret. Amvac reached a $300,000 settlement in the case Monday before the trial…The six plaintiffs…were among 12 workers suing Dole and Dow.
