CINCINNATI (AP) – Dozens of plant workers who claim their health was damaged by exposure to a chemical used to give a buttery flavor to microwave popcorn have filed lawsuits in Cincinnati against makers of the flavoring.

At least 43 workers have filed lawsuits that claim their lungs were damaged by inhaling fumes from the chemical. Some work at a local plant of Givaudan Flavors Corp. of Cincinnati, which supplies the flavoring to food manufacturers. Many others are from a plant in Marion, Ohio, owned by ConAgra Foods, which is based in Omaha, Neb.

Messages seeking comment were left at Givaudan’s Cincinnati offices and at the Independence, Mo., office of attorney Kenneth McClain, who represents many of the workers.
