§ Mrs. GormanTo ask the Secretary of State for Health what is his assessment of the effect of more invasive salmonellas than salmonella enteritidis and typhimurium on the incidence of food poisoning outbreaks.
§ Mr. FreemanFood poisoning due to salmonella is not generally regarded as an invasive disease. However, some salmonella strains are more likely than others to cause septicaemia or meningitis. For example, 28 per cent. of strains of salmonella dublin received by the PHLS division of enteric pathogens during 1981–89 were isolated from blood cultures, compared with only about 2 per cent. for all other serotypes. However, salmonella dublin is rare in humans; it accounted in 1989 for less than 1 per cent. (none in 1988) of outbreaks of food poisoning reported to 517W the PHLS communicable disease surveillance centre. In contrast, salmonella enteritidis and salmonella typhimurium together accounted for 82 per cent. of reported outbreaks in 1989 (76 per cent. in 1988). These two strains therefore represent the greatest burden of human illness.
