§ Mr. Peter Bottomley
To ask the Secretary of State for Scotland how many cases of listeriosis were recorded in each of the past five years; and what were the main causes. 
§ Lord James Douglas-Hamilton
The numbers of cases of human listeriosis reported to the Scottish Centre for Infection and Environmental Health during the period 1990 to 1994 are as follows. Although no specific source of infection was identified for these particular cases, there is general agreement, based on international experience, that food-borne infection is the predominant means of transmission. Hospital-acquired infection and person-to-person spread are also recognised, but these are less common routes of transmission.
