Indiana authorities are warning consumers in several states, including Wisconsin, Thursday that Meadow Valley Farm brand sharp cheddar cheese may be contaminated with salmonella and should be thrown out.

The cheese has been sold since May 1 at farmers’ markets and specialty food stores in and around Rockville in western Indiana, Middlebury in northern Indiana, and at least one undetermined outlet in Wisconsin, the Indiana State Board of Animal Health said in a news release. The cheese also has been sold directly from Meadow Valley Farm in Parke County, a tourist destination near the Illinois border.

The farm is a small Amish producer with no telephone, and a distributor, who also is Amish, took the cheese to an undetermined number of other outlets. The cheese can be identified by a round product label with the words "Natural Raw Milk Cheese." Also printed on the label are "Meadow Valley Farm" and "Made in Parke County" below a red barn.
