Flood waters can carry microbial and chemical contaminants that can be harmful to humans. Food crops should be assessed to determine if they have been affected by flooding surface water sources including rivers, lakes, or streams. These waters are the highest risk for contaminants. The biggest question to ask is has the edible portion of the crop been exposed to these waters? There is no way to ensure that food crops that have come in contact with contaminated flood waters are safe to eat. Food crops that have been exposed to flood waters should be destroyed so they do not enter market channels. For more information and guidance on how to handle crops and fields that have been flooded visit the Produce Safety Alliance Food Safety for Flooded Farms resource.
