YWN actually posted a pretty good article, “An Inside Look At Cholov Yisroel” in Sept. 2009.
Several authorities confirmed a spoilage problem, and blamed it on ““poor handling of the milk both in transportation and in storage in supermarkets.”
Obvious questions are; Why have these problems been allowed to exist in a product as crucial as milk?
How can a small grocery or bodega keep their milk fresh while stores selling CY have
problems?
