The faecal excretion rate of salmonellae in migratory wild ducks is higher than previous studies would indicate. Examination of 477 duck droppings during the winters of 1968/69 and 1969/70 gave isolation rates of just over 4 per cent. The commonest serotype was S. typhimurium; seven different phage-types were found, 2a being the most frequent.
