Authorities in the central city of Da Nang said they have found excessive levels of E. coli in samples of Chinese common beans and lettuce sold at a wholesale market.
A source from city agriculture quality management department said the samples were obtained from a shop at Hoa Cuong wholesale market owned by a woman only identified as Pham Thi G., news website VietNamNet reported.
The E. coli level in the lettuce was 110 times the amount permitted in Vietnamese food products, and in the bean, 2.4 times.
Da Nang authorities merely said the E. coli found was pathogenic, without saying which pathotype it was. E. coli is a large group of bacteria that are mostly harmless, though some can cause diarrhea, urinary tract infections, respiratory illness, pneumonia, and other illnesses.
Health officials had taken 26 samples of vegetables imported from Chinese for testing.
