In four out of five investigated kinds of products it was proved that most fresh samples met the microbiological requirements of Czechoslovak State Standard CSN 58 3601 and it is even feasible to consider a stricter approach to the evaluation of the total number of microbes [CPM] to 10(5) per g and in the number of coliform microbes to 10(3) per g. On contrary the amount of yeast in most fresh samples [62%-100%] exceeded the permitted limit and reached the value of about 10(4) per g. The comparison of the results of the investigation of fresh and stored samples indicates that from the eight groups or kinds of microorganisms under study the highest rate of reproduction was in yeast. In the other microorganisms the increase was not so great nor did it occur. No pathogenous microorganisms of salmonella were determined by the orientation method, and staphylococci was proved by direct cultivation in just one kind of product.
在所调查的五类产品中,有四类证明大多数新鲜样品符合捷克斯洛伐克国家标准CSN 58 3601的微生物要求,甚至可以考虑采取更严格的方法来评估每克微生物总数[CPM]至10⁵以及每克大肠菌群微生物数至10³。相反,大多数新鲜样品中酵母的含量[62%-100%]超过了允许限度,达到了每克约10⁴的数值。新鲜样品和储存样品的调查结果比较表明,在所研究的八组或种类的微生物中,酵母的繁殖率最高。在其他微生物中,增加幅度不大或没有增加。用定向方法未检测到沙门氏菌等致病微生物,仅在一种产品中通过直接培养证明有葡萄球菌。
