Caption:
These two 1929 photographs depicted a comparison between a healthy cow udder on the left, and a tuberculous cow udder on the right. The photograph was used, as an aid to livestock owners and health inspectors, in order to help them to recognize the condition referred to as bovine tuberculosis, which could contribute to the bacterial contamination of raw, unpasteurized milk. This was one of a series of instructional images, used by the Minnesota Board of Health, to train the state’s public health workers. The purpose of these images, and the training, was focused on protecting food supplies from bacterial contamination.
