Research on the status of contamination of some foods through hazard monitoring in Nam Dinh province from 2017 to 2021

Abstract

The recall descriptive study was implemented in the period 2017-2021 of 5,696 food samples (about 1,139 samples/year) in the Nam Dinh Provincial Department of Food Safety and Hygiene. The ratios of microbiology and physicochemical parameters which do not meet the regulation were 4.46% and 3.54%, respectively. Meat and its products were microbiology contaminated at the highest ratio of 8.4%, followed by vegetables and their products were 4.09%, cereals and their products were 3.5%, and non-alcoholic beverages were 2.27%. The main causes of microbiology contamination were Coliform at 4.97%, E. coli at 3.69%, and Pseudomonas at 4.62%. The physicochemical contaminations in meat products were mainly borax at 8.64 %, and the rancidity in frying oil was 19.5 %. Ensuring food safety in recent years has seen positive changes; the ratio of contamination in food surveillance in hazard monitoring in the period 2017-2021 sharply decreased compared to the previous period.
