✦ Synopsis

A preliminary survey on the contamination of clams and seawaters in various towns in Tolo Harbour was carried out using bacteriological tests . The `percentage clean' method and the 'most probably number' method were employed . The pH, salinity and temperature of the seawater were also tested in the field .

It was discovered that the number of coliform bacteria obtained by the percentage clean' was zero in both seawater and clams from all sites including the control . The most probable number' indicated that the water and the clam tissue collected in the three sites in Tolo Harbour ranged from 15-1,100/ 100 ml in the water and 825-11,ooo/g in the clams compared witho/ tooml and 115/g of the control site .

Due to the high level of organic pollution in Tolo Harbour, improvement of the sanitary situation is urged . Cultivation of clams collected in this area in clean and sterilized water for a few days before consumption is recommended .
