Abstract:
Objective:To determine over-limit status of sodium nitrite in cooked meat products in Hunan Province,and to provide scientific evidence for making health supervision.Methods:In accordance with the national standards for sampling and testing,data were analyzed by classical and spatial statistic methods.Results:The total over-limit rate of sodium nitrite was 5.5％ in 731 samples.The relative higher sodium nitrite over-limit rates were Xiangxi Tujia and Miao autonomous prefecture and Zhangjiajie.October and February were the main months in nitrite over-limit.Five regions with over-limit of sodium nitrite in cooked meat products were detected in Hunan.Conclusion:With obvious space-time clustering,over-limit of sodium nitrite in cooked meat products is a common problem particularly in northwest Hunan and Zhuzhou City.Supervision in October should be further strengthened in above-mentioned areas to guarantee the consumers health.
