The occurrence of Listeria species in pâté: the Cardiff experience 1989.
Samples of 216 pâtés were examined for the presence of Listeria spp. between May and August 1989; 35% were contaminated with L. monocytogenes, 5% of samples having counts of greater than 10(4)/g. L. innocua was recovered from 2% of samples but no other species was isolated. Five serotypes of L. monocytogenes were represented (1/2, 4b, 4b(X), 4 not 4b or 4b(X), and NT), 4b was the predominant serotype and multiple serotypes were found in eight pâtés. The incidence of contamination with L. monocytogenes was greater in stored pâté (46%) than display pâté (30%). Sampling over a 21-day period showed an apparent increase in numbers of L. monocytogenes in 6 of 7 samples with multiple serotypes represented. There was no correlation between contamination of pâté by L. monocytogenes and the presence of coliforms. Comparisons are made between the contamination of soft cheese and pâté.

How is the source of food poisoning outbreaks established? The example of three consecutive Salmonella enteritidis PT4 outbreaks linked to eggs.
Three consecutive outbreaks of Salmonella enteritidis PT4 occurred in Wales in 1989 in which epidemiological and microbiological investigation established eggs as the likely source although kitchen inspection and food preparation histories suggested other vehicles of infection. This paper examines the contribution of analytical epidemiology in attributing causation, with particular reference to those limitations which are regarded as inherent in epidemiological evidence. Such evidence, implicating eggs in the three outbreaks, fulfilled 6/7 widely accepted criteria for causation; data to assess the seventh were lacking. Collaboration between different agencies and professionals in investigating outbreaks is very important.

Citrobacter koseri meningitis in a special care baby unit.
An outbreak of meningitis due to Citrobacter koseri in a special care baby unit is described. The organism showed a high capacity for spread among the babies on the unit and although the intestinal carriage rate was high, the clinical case:carrier ratio was low.

The bacteraemia associated with burns surgery.
Fifty-four surgical procedures on 39 burnt patients were studied with serial blood cultures. In 25 (46 per cent) of these procedures the cultures were positive. In spite of the absence of prophylactic systemic antibiotics there were no clinical manifestations and not one of the bacteraemias developed into a septicaemia. The role of natural immunity in controlling the bacteraemia is discussed and it is suggested that prophylactic systemic antibiotic therapy covering burns surgery is unnecessary in the presence of normal immunoglobulin levels.
