Floods across Wisconsin have damaged homes and roads, but they can also damage crops and animal feed. Flood waters can carry harmful chemicals and pathogens like toxic mold, which can easily poison feed and silage. State ag spokeswoman Donna Gilson says if you think your crops have been damaged in the field or in a silo, talk with your local extension office. If you are going to lose your crop, make sure you contact your insurance or extension office to find out how best to proceed.
