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.
2017 - 2021年南定省部分食品污染状况危害监测研究
召回描述性研究在2017-2021年期间对南定省食品安全和卫生厅的5696个食品样本(约1139个样本/年)进行了召回描述性研究。微生物学参数和理化参数不符合规定的比例分别为4.46%和3.54%。肉类及其制品受微生物污染的比例最高,为8.4%,其次是蔬菜及其制品(4.09%)、谷物及其制品(3.5%)和非酒精饮料(2.27%)。微生物污染的主要原因为大肠菌群(4.97%)、大肠杆菌(3.69%)和假单胞菌(4.62%)。肉制品的理化污染主要为硼砂(8.64%),油炸油中的酸败(19.5%)。确保食品安全近年来发生了积极变化;2017-2021年期间,食品监测中的污染在危害监测中的比例与前一时期相比急剧下降。
