After a decade of purchasing Lucerne milk (non-fat or 1%) from the SF Marina Safeway without incident, I now encountered two problems with Dairy Glen 1% milk, distributed by Safeway/Pleasanton, and purchased at the SF Marina store.

I no longer have the container for the other gallon that went bad before its expiration date, but I have the second one: 79893-15005. Both were refrigerated properly, not left at room temperature, and yet both curdled and turned sour before the expiration date.
