"'Swill milk' scandals"

An appealing story at the Times on the newfound popularity of condensed milk:

Sweetened condensed milk came on the United States market in 1856, the brainchild of Gail Borden, a chronic culinary inventor. (He had already patented a prototype of a complete nutrition bar, which he called a “meat biscuit.”) Mr. Borden began experimenting with sterilized milk after a series of “swill milk” scandals that revealed the true contents of much of the milk then for sale in American cities: chalk powder, molasses and vermin.
