Liver fluke and helminths appear in the south

Scientists have discovered signs that fish reared in the southern region may be infected with liver fluke, instead of being found only in the north as long as they think, and eels in some places also in the area This area is infected with helminths.

In the framework of the Fisheries Parasite Project (FIBOZOPA), the Institute of Fisheries Research II in Ho Chi Minh City conducted an analysis of 600 samples of pangasius from fish farms of the Delta households. Kowloon.

While only 2% of samples with intestinal flukes were detected, the scientists were surprised to find liver fluke in catfish (snake head) collected from a local market.

'If confirmed, this will be a new and important sign that liver fluke is present in fish in the southern part of our country,' said a scientist from FIBOZOPA.

Ho Chi Minh City Tropical Hospital also found a dangerous species of parasites (helminths) in eel, a very popular aquatic species in pubs in Ho Chi Minh City. This worm is known to cause many serious diseases for humans when they are easily moved under the skin as well as in the patient's digestive system.

After a survey of 600 samples from October 2005, scientists continued to closely monitor the samples collected during the 2006 rainy season and the results will be announced soon.

Saltwater and brackish water fish can also cause illness in humans

Not only freshwater fish but also salt water and brackish fish in Vietnam also carry parasites that cause disease to humans, the initial assessment of FIBOZOPA said.

At the beginning of the FIBOZOPA Project, scientists knew very little about the presence of aquatic-borne human parasites (FZP) on fish species in brackish and water environments. sea.In general, it is only known that FZP is usually present on freshwater fish.

However, after analyzing 150 samples of brackish and saline fish in Vietnamese waters in Khanh Hoa province, scientists from the III Fisheries Research Institute saw super FZP larvae found in grouper and fish. for.

From this initial discovery, for the first time FZP was found on fish that did not live in freshwater environments, the scientists identified it was time to study on a large scale the food safety issue of fish groups. Saline and brackish water are also being consumed more and more in our country.As known, within the framework of FIBOZOPA, research projects are being urgently promoted.
