Phase out Antibiotics in Animal Feed
Shareholders request the board to adopt the following policy and practices for both the companys own hog production and (except when precluded by existing contracts) its contract suppliers of hogs:
(1) phase out routine use of animal feeds containing antibiotics that belong to the same classes of drugs administered to humans, except for cases where a treatable bacterial illness has been identified in a herd or group of animals; and
(2) implement animal raising practices that do not require routine administration of antibiotics to prevent and control disease, and where this is not feasible, use only antibiotics unrelated to those used in human medicine; and
that the Board report to shareowners, at reasonable cost and omitting proprietary information, on the timetable and measures for implementing this policy and annually publish data on types and quantities of antibiotics in the feed given to livestock owned by or purchased by Tyson.
