Vietnam Study finds bacteria in Vietnamese pork
Salmonella is a common pathogen causing diarrhea, abdominal pain, fever and septicaemia in humans. Another article published by the same research team found the human antibiotic drug chloramphenicol was found in 11% of the packaged feed samples tested and 4% of the pork in Hưng Yên and Nghệ An provinces, despite being banned in livestock production.
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.
