As always, Robert W's reply is very helpful. My sense is that transport, even in refrigerated trucks, in the height of the summer, esp. during construction and delays, also impacts all the refrigerated products we buy. I find the local eggs at Jensen's, that are from farms in Redlands, for example, last much longer, and taste better, than other eggs.
That said, I drink Trader Joe's Vanilla Rice Drink 95% of the time. Comes in a carton with a shelf life of about 9 months. I can buy many at a time for the pantry and don't have to worry about running out. Once open, refrigerate and use w/in 7-10 days. I also drink almond milk.
When I do need cows milk for something (recipe, guest, a change) I buy Horizon or Alta Dena organic milk at Jensen's and it always lasts beyond the expiration date. I've been surprised how long it lasts, actually. Same thing w/1/2 and 1/2 or cream. No problems so far.
My fridge is also very cold no matter what setting I put it on. To our health and proper food storage!
