An investigation of the bacteriological quality of retail vanilla slices.

One hundred and thiry-three vanilla slices, purchased from shops in the West Yorkshire Metropolitan County, were examined to determine the numbers and types of bacteria present at the time of purchase. The surface colony count at 37 degrees C was greater than 10(3)/g in 67/133 (50%) of the samples examined, Bacillus cereus being found at that concentration in 21.8%, coliform bacilli including E. coli in 5.3%, Staphylococcus aureus in 3-0% and Streptococcus faecalis in 0-8%. Thirty-four strains of B. cereus were serotyped and 11 (32%) of these were typable with the sera available. Preparation of custard mixed in the laboratory suggests that the milk or milk powder used in the mix may be the major source of B. cereus in the final product. Many of the present methods of manufacture, distribution and storage allow organisms present in the custard at manufacture the opportunity to multiply and possibly reach numbers which present a risk of food poisoning.

Pilot study of old-age pensioners.

Two groups of old-age pensioners in St. Paul's Cray were screened for physical illness, social and family connexions, and personal activities. The first group comprised 100 people (10% random sample of a suburban practice of 12,000 patients), and the second group comprised the total population of a sheltered area (85 people).The findings showed that geographical separation of relatives was a significant factor in the isolation of old people. Lack of exercise and obesity seriously increased the risk of urinary infection; malnutrition and nutritional anaemia were found to be other potentially important problems in the elderly. In 13% of the elderly population three out of five seriously adverse factors (over 80, isolation, housebound, living alone, serious chronic Illness) were found to be present.It is imperative that the group of high-risk elderly should receive the services they need; it is suggested that a policy of an adequate sheltered area supported by a geriatric service should be an extension of group medical practice.
