...known laboratory infections (about 6000 recorded in the history of microbiology) have been largely respiratory infections, spread by droplets (mostly before safety cabinets were introduced in the 1940s). Enteric infections, however, occur through swallowing of contaminated food or other material. Even the most virulent enteric pathogens are relatively safe to handle in the laboratory with simple precautions, such as not putting food or a cigarette on the laboratory bench...

Similarly, in the Communicable Disease Center of the U.S. Public Health Service 150 laboratory infections were recorded, with one case of transmission to a relative. Elsewhere in the world there have been about two dozen laboratory-based microepidemics recorded, each involving a few outsiders...
