Many foods are unregulated. It's strange that milk, for example, doesn't have any requirements for its expiration date. One brand widened their "best buy" date and I noticed their milk was souring 3 days before the "best buy" date. After contacting them several times, I told them that they gave me no option but to escalate this to authorities, they didn't seem concerned a bit, and after doing my research, I found out that they can put anything on the label without repercussions. The manufacturer even recommended the record stupid stuff like using the milk in smoothies and other odor and taste masking means to make it "best." So, even "best buy" for foods that can make you sick is meaningless!
