We examined a total of 54 samples, including 18 body lotions and 36 talcum powders, for their total aerobic bacterial, coliform and fungal counts. We also carried out anaerobic bacterial counts for talcum powder as well as tests to detect some potentially hazardous bacteria in all tested samples. Talcum powders were more heavily contaminated with bacteria and fungi than body lotions. More than 40% of the tested body lotions contained no viable bacteria or less than 100 c.f.u./g. while all the talcum powders tested contained more than 100 c.f.u./g. Thirty per cent of the talcum powders were contaminated with 10(4) c.f.u./g. and none of the body lotions were contaminated to that extent. No coliforms were recovered from any of the body lotions, while 17% of the talcum powder examined contained coliforms in the range of 230-500 c.f.u./g. Staphylococcus spp. were detected in 18 samples of both talcum powders and body lotions, three of these Staphylococci were of the aureus type. Three samples of talcum powder contained E. coli, two samples contained Enterobacter agglomerans and one sample contained Citrobacter freundii. Seventy per cent of the body lotions showed no fungal counts, while 83% of the talcum powders examined were contaminated with fungi and most of the contaminated talcum powders contained more than 100 fungal cells/g. With regard to the anaerobic bacterial counts for talcum powders, 50% of the samples showed no counts while the other 50% contained less than 100 c.f.u./g. Four samples were contaminated with Clostridium perfringens, although C. tetani was not recovered from any of the samples.
我们总共检测了54个样本,包括18款身体乳和36款滑石粉,检测其需氧菌总数、大肠菌群数和真菌数。我们还对滑石粉进行了厌氧菌计数,并对所有检测样本进行了一些潜在有害细菌的检测。滑石粉比身体乳受到的细菌和真菌污染更严重。超过40%的受试身体乳不含活菌或每克少于100 c.f.u.,而所有检测的滑石粉每克含菌量均超过100 c.f.u.。30%的滑石粉每克被10⁴ c.f.u.污染,而身体乳均未被污染到这个程度。在任何一款身体乳中均未检出大肠菌群,而17%检测的滑石粉每克含230 - 500 c.f.u.的大肠菌群。在滑石粉和身体乳的18个样本中均检测到葡萄球菌属,其中3株葡萄球菌为金黄色葡萄球菌。3个滑石粉样本含有大肠杆菌,2个样本含有成团肠杆菌,1个样本含有弗氏柠檬酸杆菌。70%的身体乳未检出真菌,而83%检测的滑石粉被真菌污染,且大多数被污染的滑石粉每克含真菌细胞超过100个。关于滑石粉的厌氧菌计数,50%的样本未检出,另外50%每克含菌量少于100 c.f.u.。4个样本被产气荚膜梭菌污染,尽管未从任何样本中检出破伤风梭菌。
