Scenario: One hot summer day a dairy farmer on a large operation in Idaho notices several milking cows unwilling to rise. Initially he thinks that they are too hot, but later that day when they still have not risen, he becomes concerned. On closer investigation he finds that although the cows appear to be alert to their surroundings, they refuse to rise. The cows die later that night. The next day the farmer calls the local rendering company to collect the carcasses. The rendering truck arrives the next morning. However, an additional three cows died that night and more cows appear to be developing similar symptoms. The renderer is only able to load a few cows that day. In the intense heat, the dead cows rapidly start to decompose. There are many more cows than the local rendering company can handle. In the meantime the farmer continues to milk the remainder of his herd. The veterinarian makes a tentative diagnosis of intoxication via the feed. Not knowing for sure the source of intoxication, the farmer decides that he should not use any of the feed ingredients on his farm until they have been determined to be safe. What are some public health concerns that have arisen?
