Food safety related to pork consumption: A rapid integrated assessment in Hung Yen and Nghe An, Vietnam

  1. 1. FOOD SAFETY RELATED TO PORK CONSUMPTION: A RAPID INTEGRATED ASSESSMENT IN HUNG YEN AND NGHE AN, VIETNAM Nguyen Viet Hung1,2, Nguyen Tien Thanh1, Luu Quoc Toan1, Dang Xuan Sinh1, Pham Duc Phuc1, and Delia Grace2 1Center for Public Health and Ecosystem Research (CENPHER), Hanoi School of Public Health, Hanoi, Vietnam, hung.nguyen@unibas.ch Livestock Research Institute (ILRI), Hanoi, Vietnam and Nairobi, Kenya 2International Meat quality Introduction In Vietnam, pork makes up 75% of meat consumed, with its production delivering substantial benefits to the smallholders who supply 84% of the market. However, pork contains high levels of pathogens, an issue of growing concern among the public, and policy makers alike. To respond to these concerns, we developed a rapid integrated assessment tool with partners to assess food safety and zoonosis related to pork value chain and tested it in different countries. This study presents the results of this rapid assessment of food safety and zoonosis from a consumer perspective and with analysis of biological samples. 2.E+06 Hung Yen 1.E+06 Nghe An 5.E+05 * 0.E+00 TBC (CFU/g) Materials and Methods Study sites in Hung Yen and Nghe An province * Hung Yen: Population: 1.1 million Coliforms (MPN/g) Fig 1.

Meat was bough mainly from the informal market and quickly prepared, cooked and consumed. People had high trust in pork safety and quality and rarely attributed health issues to pork consumption. • Raw pork is rarely eaten except for fermented pork (nem chua). • Main concerns: growth promoters, pork refresher (chemicals used to make not fresh pork appear fresh) as well as diseased pork. • Little knowledge of zoonosis diseases. • Pork portions perceived as rich in nutrients were used young children and special care was given to their preparation, such as cooking well or making into soup. Nghe An Conclusion and discussion • TBC and pH of pork were within the allowable range of standards of Vietnam whereas coliforms concentration was exceeded (TCVN 7046: 2002, TBC ≤ 106 CFU/g and coliforms ≤ 102 MPN/g). • Hung Yen slaughterhouses and markets seemed to have better hygienic conditions than Nghe An. • Meat is a main animal food source in Vietnam and women are responsible for buying and preparing pork. • While the trust in pork quality was high, microbial and physiochemical analyses suggest further studies to address consumers’ concern on chemical contamination.
