West Virginia agricultural officials are advising growers to discard vegetables that have had contact with flood waters.

The advice comes after weeks of rain that promoted Gov. Earl Ray Tomblin to declare states of emergency in 10 counties this week.

West Virginia extension agent John Bombardiere says the safest way to deal with lettuce, tomatoes or potatoes that have been tainted by flood water is to toss them. He says they should not be consumed by humans or animals.

The advice is based U.S. Food and Drug Administration guidelines, which state there is no practical way to salvage the product.
