SUMMARYA survey on the bacteriological quality of both drinking water and flavoured drinks from coin-operated vending machines is reported. Forty-four per cent of 25 drinking water samples examined contained coliforms and 84% had viable counts of greater than 1000 organisms ml at 30 'C. Thirty-one flavoured drinks were examined; 6 % contained coliforms and 39 % had total counts greater than 1000 organisms ml. It is suggested that the D.H.S.S. code of practice on coinoperated vending machines is not being followed. It is also suggested that drinking water alone should not be dispensed from such machines.
