The latest popcorn trial is underway in Joplin, while the company that lost the first trial is appealing that verdict.Former popcorn factory worker Louis Ed Pennell and his wife Ronetta charge that breathing the butter flavoring used at the popcorn factory in Jasper has caused him irreversible lung damage. He says he’ll need a double lung transplant in five or ten years. While that case is going on, the makers of the butter flavoring are appealing a $20 Million award given a Carthage couple in the first lawsuit to be heard. The appeal has been filed after the judge in the case refused to hold a new trial.
