FORT SMITH, Ark. (AP) _ One of four men named in a 52-count federal indictment stemming from a tainted milk scandal says he is innocent of charges that he manufactured and sold pesticide-contaminated feed to farmers in three states.

Jerry L. Finley, 40, of Tulsa, Okla., pleaded innocent Thursday before U.S. Magistrate Ned Stewart. Finley is the former president of Valley Feeds Inc. of Van Buren, Ark.

Innocent pleas also have been entered by the three other men named by the federal grand jury: Jack E. White, 65, of Van Buren, the manager and principal stockholder of J.E.W. Inc., a Van Buren gasohol plant and its subsidiary, Valley Feeds; Brownie C. McBride, superintendent of the two companies; and Henry White, 62, of Van Buren, a corporate officer of Valley Feeds.

Authorities have accused the four of selling cattle feed contaminated with the pesticide heptachlor to farmers in Arkansas, Oklahoma and Missouri. Heptachlor is a cancer-causing pesticide banned by the U.S. Food and Drug Administration in 1975. Dairy cows became contaminated after eating the grain.

In Arkansas, authorities quarantined more than 100 dairy herds, recalled thousands of gallons of milk and tested thousands of milk samples for contamination.

Included in the indictment are charges of racketeering, mail fraud, wire fraud, intertstate transportation of money taken by fraud, federal food and drug violations, water pollution violations and providing false statements.
