(c)a private water system that is tested regularly for Coliform and E.Coli as recommended by the Eastern Ontario Health Unit.

（c） 按照安略省东部卫生部门的建议，定期进行群和检测的私人供水系统。

Of all the homes tested, they also found Coliform- a family of bacteria that includes E. coli and Salmonella- present in around 81% of them, and mold and yeast in about 31%.

在所有被测试的家庭中，他们还发现——包括和沙门氏在内的一个细家族——在81%的家庭中都有存在，霉和酵母在31%左右。

So we got the idea from Swedish farmers and it's very simple because you take a sample of milk and you test for total viable count, that's all of the bacteria and the other one is coliforms.

所以我们从瑞典农民那里得到了这个想法， 很简单，就是取一份牛奶样本， 检测总数，也就是所有的细， 另一个是群。
