Toxic bacteria found in seafood samples

The septic waste is returning to our food. The latest indicator is the presence of toxigenic E coliin seafood samples collected from retail markets, fish farms and landing centres in Ernakulam district and neighbouring areas. The presence of E coli signifies the faecal sewage contamination in food and water.

Over the past one year, around 123 samples of fish were taken and analyzed at the Central Institute of Fisheries Technology (CIFT), which is a nationally-accredited agency by the Food Safety and Standards Authority of India (FSSAI) for testing the quality of fish.

The study team, consisting of Dr K V Lalitha, V Murugadas and Toms C Joseph, screened the fish samples, including shellfish. Pathogenic E coli was found in 23.4% of the 123 seafood samples while other strains, especially enterotoxigenic E coli (ETEC), was seen in 18.6% of the specimens.

The presence of E coli in food items can cause severe diarrhoea in humans. There were about 10,457 cases of acute diarrhoea reported in Ernakulam in the first five months of this year.

“The study showed that our waterbodies are contaminated by septic waste. The toxic bacteria can enter into our food chain from any point, starting from catching of fish on board a fishing vessel or aquaculture farms to the point of sale in retail markets.The presence of E coli is usually linked with the use of contaminated water in food production chain,” Lalitha said.
