“…An important finding was that 77 % of the shucked raw oyster meat from the four areas of Western Trinidad studied was contaminated with E. coli. Variable prevalences of E. coli in oyster meat have been reported by others in the United States of America [21,22]. The 77 % prevalence of E. coli in the present study is considerably lower than the 98 % rate reported for fresh oysters sampled immediately, postharvest, from the estuarine habitat of the Caroni Swamp [11].…”

The prevalence and characteristics of Escherichia coli and Salmonella spp. as well as counts of E. coli in raw oysters, condiments/spices, and raw oyster cocktails sampled from 72 vendors across Western Trinidad were determined. The microbial quality of the water used in the preparation of raw oysters was also investigated. Of 200 samples each of raw oysters, condiments/spices and oyster cocktails tested, 154 (77.0%), 89 (44.5%) and 154 (77.0%) respectively yielded E. coli. The differences were statistically significant (P = < 0.001; chi square = 62.91). The mean E. coli count per g in the ready-to-eat oyster cocktail ranged from 1.5 x 10(3) +/- 2.7 x 10(3) in Couva to 8.7x10(6) +/- 4.9x10(7) in San Fernando. One hundred and forty-six (73.0%) oyster cocktails contaminated with E. coli had counts that exceeded the recommended standard of 16 per g. Of a total of 590 E. coli isolates from various sources tested, 24 (4.1%), 20 (3.4%) and 69 (11.7%) were mucoid, haemolytic and non-sorbitol fermenters respectively. Twelve (2.0%) isolates of E. coli were O157 strains, while 92 (46.0%) of 200 E. coli isolates tested belonged to enteropathogenic serogroups. Ninety (45.0%) and 73 (36.5%) of 200 water samples contained total coliforms and faecal coliforms respectively, with counts that exceeded 2.2 coliforms per 100 ml. Salmonella spp. were isolated from 7 (3.5%), 1 (0.5%) and 2 (1.0%) of 200 samples each, of raw oysters, condiments/spices and oyster cocktails respectively. Oysters pose a health risk to consumers in Trinidad, particularly from colibacillosis and salmonellosis, and the need for increased public awareness of this hazard cannot be over-emphasized.

The work was aimed to study prevalence of Escherichia coli contamination in fish and shrimp sold in retail markets at Kolkata, India in different seasons. E. coli was identified by standard microbiological, biochemical tests, and further confirmed by 16S rRNA PCR.The faecal coliform loads in fish and shrimp samples were assessed. The bacterium was detected in 138(80.70%) samples out of 171 numbers of samples collected from different retail fish market in and around Kolkata. E.coli was detected in fish (65%) and shrimps (85%).E.coli had increased remarkably in summer months than winter.
