I posted about that on HV's forum and he responded a couple of days ago. I recall you saying you were in NY also. I suspect many of these products are getting killed in shipping as most are shipped in from the west coast. HV also suggested they may be killing the bacteria at the factory for products that are shipping cross country just to ensure longer shelf life. Due to 9/11, I also suspect that much of what comes into NY is x-rayed which would also affect the bacterial content. You can dig my post up and see the brands that I tried. Please let me know if you find something else that works.
