VIETNAM, Hà Nội. Forty eight out of 108 (44%) cut pork meat samples collected at wet markets in Hưng Yên Province were found to contain the disease-causing bacteria Salmonella. The finding, based on research conducted from 2014 to 2015, was published recently in a research paper. This was reported by Việt Nam News.
These findings resulted from analysing 514 samples of pig feed, meat, liver and kidney for antibiotics and heavy metals. Using chloramphenicol in livestock production can hasten the development of drug resistance in bacteria, making treating bacterial infections in people more difficult and expensive.
The researchers also found lead in 28% of the samples but at levels below maximum residue limits and so not dangerous when consumed. Hùng and his co-authors applied risk-based approaches promoted by the Vietnamese Food Safety Law but not yet widely applied. These approaches, Hung said, should be expanded to determine human health risks of other food commodities.
