Can somebody help me regarding to interpretate a lab-analysis report on green tea, that we use in one of our programmes.

With our specifications the following discrepancies were found:

-Admixture found 0.16% against 0.1% specified and -Yeast and moulds found 3000 col/g against 2.2 x 1000 col/g specified.

I am urgently looking whether these levels are acceptable or not and will highly appreciate your advice asap.

Mr. Timmer,

Although I'm not an expert, perhaps the "admixture" is "non-tea" components such as other leaves, twigs, or assorted airborne debris (tea is often air dried in the field). The yeasts and molds probably are air-born soil types. The differences between the levels found and the specification are not of practical importance except in law enforcement.

The specification based on % admixture and yeast count is more of qualitative parameters than "fit for human consumption". It shows that the quality of the undermentioned tea is lower than the specified. perhaps a price cut or reduction to the supplier will be the right action. Of course, if it is not late we can reject also. But I personally feel that there is no health hazard.
