"Different Kinds of Milk Bacteria. It is not uncommon for a large number of person to be poisoned from eating ice cream at some public gathering. This is caused by a change in the milk brought about by the presence of bacteria. The poisonous product of their action called "tyrotoxicon", may also be found in other foods which have milk as their basis, such as cheese, custard, and so on. There are vomiting and purging within a few hours after eating the food, succeeded by a great nervous prostration, from which recovery follows slowly." — Blaisedell, 1904
