目的:了解保健食品微生物污染状况。方法:采用GB4789规定的检测方法,对2007年-2011年厂家送检及现场抽检的保健食品进行菌落总数、大肠菌群、霉菌、酵母菌和致病菌检测,并进行统计与分析。结果:共检测保健食品1257份,总合格率为89.90%,菌落总数、霉菌超标率较高,未检出致病菌。各年度间合格率差异有统计学意义(P<0.05);现场抽检产品的合格率明显高于企业送检产品(P<0.01);不同剂型保健食品合格率之间比较、不同原料保健食品合格率之间比较、不同剂型保健食品菌落总数超标率之间比较、不同剂型保健食品霉菌超标率之间比较,其差异均有统计学意义(P<0.01);大肠菌群和酵母菌各剂型间差异均无统计学意义(P>0.05)。结论:河南省检测的各类保健食品存在不同程度的污染,主要是菌落总数和霉菌污染,其原因可能与原料及加工过程污染有关。
Objective: To understand the health food contamination status. Methods: The detection methods of GB4789 were used to detect the total number of colony, coliform bacteria, molds, yeasts and pathogens in the health foodstuffs from 2007 to 2011 and the spot checks. The statistics and analysis were carried out. Results: A total of 1257 health food products were tested, with a total pass rate of 89.90%. The total number of colonies and mold exceeded the standard rate, and no pathogenic bacteria were detected. (P <0.05). The passing rate of sampling products on the spot was significantly higher than that of the products examined by the enterprises (P <0.01). The pass rates of different types of health food products were different, and different raw health food products passed the certification The differences between the rates of over-standard colonies of different types of health-care foods were statistically significant (P <0.01). The differences of coliform and yeast dosage forms There was no significant difference (P> 0.05). Conclusion: There are different degrees of pollution in all kinds of health food products tested in Henan Province, mainly the total number of colony and mold pollution, which may be related to the pollution of raw materials and processing.
