Distribution and characteristics of Aeromonas in food and drinking water in Denmark.
A total of 970 Danish commercial foods and drinking water samples were examined for the presence of motile Aeromonas spp. With a detection limit of 10(2)/g the frequent prevalence in raw foods was confirmed. Aeromonas occurred in 7% of 779 samples of prepared foods; most frequently in whipped cream from ice cream parlors (28%) and mayonnaise salads (10%) with numbers occasionally exceeding 10(5)/g. The prevalence in drinking water was 28% with a detection limit of 1/100 ml. A hydrophila was the dominating species in both food and water. Hemolysin production was demonstrated in 37% of the 51 isolates tested with 10% having high titers.
