FORT SMITH, Ark. (AP) _ Three men convicted in the sale of pesticide-contaminated feed to dairy farmers, causing a eight-state milk recall, have been sentenced to prison.

Jack E. White, his brother, Henry R. White, both of Van Buren, and Brownie C. McBride of Greenwood were sentenced Wednesday on their May 22 conviction in federal court of charges stemming from the sale of heptachlor-contaminated grain to dairy farmers in Arkansas, Oklahoma and Missouri.

The sales led to milk recalls in early 1986 in Arkansas, Kansas, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Texas.

U.S. District Judge Morris Arnold sentenced Jack White, 66, to a three-year prison term. Henry White, 62, and McBride were sentenced to one year and one day in prison.

Jack White owned Valley Feeds, which health officials said was the dairy farmers' source of the contaminated grain, and operated J.E.W., a gasohol plant, where the feed was a byproduct. Henry White worked for Valley Feeds, and McBride was superintendent of the gasohol plant.

Jack White was convicted of 21 counts, Henry White and McBride were conbvicted of 20 counts each. The White brothers each were found guilty of two counts of wire fraud and two counts of interstate transportation of money, both felonies. Jack White also was convicted of one count of making a false statement.
