asked the Secretary of State for Social Services what are the particulars of the incidence of any disease attributable to the consumption of green top milk in the last three years.

In the three years 1975 to 1977 inclusive, the Public Health Laboratory Service recorded in England and Wales, in relation to cases of food poisoning, 372 isolations of salmonella attributable to the consumption of untreated milk and 30 of campylobacter thought to be attributable to the same cause. Records do not distinguish between bottled and unbottled untreated milk.
