A 21 -year -old woman patient, from middle of February 2003, she had got fatigue, weight loss 5-6 kg within 3 weeks, bad appetite, indigestion. Then she had pain in right lower rib, 390C fever, cough, dry vomitting. She had got diagnosis of hepatic abscess and unsuccessfully treated by 10 days antibiotics. She had got cecal abscess and abscess block was removed. Stool examination found Fasciola hepatica eggs and ELISA serum test was (+) with F.gigantica antigen (collected from buffaloes and cows) by title of 1/12800, acidophil white blood cell 12%. Triclabendazole 10mg/kg gave good results.

Analysis samples of meat and seafood... in Hanoi markets to determine infections of larva of parasites. Results: among 144,390 beef samples and 2,237,000 pork samples, prevalences of parasite infection were 0.027% and 0.003%, respectively. The rate of liver fluke metacercaria in fresh water fish was 1.7-21.7% (mean rate 5.2%), rate of Gnathostoma infection in snakehead fish and ell was 4.8-11.4%. Furthermore, in endemic areas of lung fluke, infection rate of Paragonimus metacercaria in fresh water crabs and fish was 9.7%-98.1% (mean rate 63%).

A male patient of 2,5 year old living in Vinh city, Nghe An province, who often had abdominal paine. On October 3rd, 2001, he has vomitted with 8 flukes, which were identified by morphology and lately confirmed by molecular approach in Institute of Biological Technology as Fasciolopsis buski

Lung flukes Paragonimus heterotremus is a parasitic disease in which transmit by food, occur in 8 Northern mountainous provinces . The incidence of disease is from 0.3 to 15% on human, from 3.3 to 75% on dogs, from 8.7 to 98.1% on mountain scrab and from 1.4 to 3.6 % on snail. Clinical diagnosis based on mainly symptom such as haemoptysis or fluid pleurisy. Diagnosis definetely that have eggs of lung fluke in sputum, in fluid or in feces. Specific treatment medicine is praziquantel. Prevention of its disease by education communication for people and detective patients ealry then use specific treatment medicine

Toan Son commune (Da Bac district, Hoa binh province) and Quy Huong commune (Moc Chau district, Son la province) are remote mountainous areas. Methods as interview, stool examination by Kato technique, sputum examination and snail examination by direct technique, crab muscle digestion were used in the study. Results of the study, showed that rate of people having habit of eating raw crab was 73.0% in Toan Son and 72.2% in Quy Huong; paragonimiasis rates were 3.3-11.3% and 3.4-15.7%, Ascaris infection rates was 52.3% and 50.0%, hookworm infection rates was 33.0% and 35.9%, Trichuris infection rates was 29.7% and 4.3%, clonorchiasis infection rate was 0.7 % (in Toan Son only), Taenia infection rates was 0.4% and 0.3%.In these communes, dogs, crabs and snails were also infected with paragonimus.

Vietnam is country with tropical climate, population community's life comform to habits, therefore parasitic infections, fungal infections in foods needed interest particularily. Foods infected helminth, germs through intermediary objects such as shellfishes, crabs, fishes, pigs,... because unhygienic foods infected to human. The author indicate that with contaminated route of helminth, unicell, fungus contaminated through foods, drink water, skin, breath,... depend on helminth's type that they exist and grow in human body and cause different diseases. To limit the contamination of germ, we must sure about food safety

Sample of tapeworm was isolated from 1 patient in Ha Tay province. It was amplified by polymerase chain reaction (PCR), purified, cloned and sequenced. The nucleotide sequence was comparatively aligned with the known corresponding sequences of Taenia asiatica (Taiwanese); T. saginata (Chinese) and T. solium (Chinese and Vietnamese) and used for establishing a phylogenetic relationship for analysis of identification, using special programs. Molecular-based analysis revealed that the Taenia sp from this patient is identified as Taenia asiatica. Absolute nucleotide similarity (100%) between Taenia asiatica in Ha Tay, Vietnam and Taenia asiatica in Taiwan; the grouping together with T. asiatica (Taiwan) confirmed the sample obtained from Ha Tay is closely related to the Taiwanese T. asiatica

Molecular examination on Taenia solium cysticercus isolated from Vietnamses patients in Bac ninh province. Total DNA was extracted. PCR were performed and the nucleotide sequences were developed. Nucleotide sequences and amino acids of cob gene fraction was confronted to some species of Taenia isolated from China, Taiwan. The result confirmed that cysticercus isolated from Vietnamese is Taenia solium

4826 stool samples collected from 5 communes were examined by Kato- Katz technique. The infection rate of clonorchis sinensis was 33,9% in average (22,5% to 37,3%). The infection rate in male was higher than in female by 4 times and highest in 40- 49 age group (51,9%). The habit of eating raw fish is very common in this area (55,6%- 80,4%). The adult worms from patients in these study sites were identified as clonorchis sinensis

The survival ability of the larve of Clonorchis sinensis in raw fish dish prepared by traditional culinary method in NghiaLac commune, NghiaHung District,NamDinh province and the larve of Paragonomus heterotrimus in grilled crabs processed in KhanhHoa commune, LucYen district, YenBai province was investigated..In this raw fish dish, 93-95% of the microcerca of Clonorchis sinensis and in this grilled crab, 23,3-65% of microcerca had been living
