Aquatic edible molluscs (oysters, wedge‐shell, butter‐fish, sting‐winkle, date‐shell and sea‐urchins) caught from sea water near Alexandria were found to be grossly polluted. Most of the samples examined showed exceptionally high counts of coli‐aerogenes bacteria and enterococci; many salmonellae were also isolated. Discrimination of polluted shell fish may be accomplished by testing the sea water or more conveniently by determining the most probable number index of shell fish liquor. The coli‐aerogenes count is probably the best available standard; there is however a positive linear relationship between the coli‐aerogenes and the enterococcal counts. This conclusion, drawn from scatter diagrams, was also confirmed by the calculation of the correlation coefficient r =+ 0·9, when the logarithms of the geometric means were used. A seasonal variation in the coli‐aerogenes and the enterococcal counts of shell fish liquor was noted which could only be attributed to the temperature differences in summer and winter.
