§ Sir G. Willsasked the Minister of Health to what extent damage to human health can arise from brucellosis melitensis in cows, either through milk from such cows or any form of contact with the infected animal itself.
§ Mr. Walker-SmithOrganisms indistinguishable in the laboratory from brucella melitensis have been isolated from dairy herds in this country from time to time over the last twenty years, but no cases of human disease are known to have been caused. In the Mediterranean area a type of undulant fever, which is often a serious disease, is due to this organism and can be contracted from infected milk or by contact with infected material. Medical officers of health have powers in Regulation 20 of the Milk and Dairies (General) Regulations, 1959, to require heat treatment of milk infected with brucella, and so make it safe.
