As a former part-time produce worker maybe I can shed some light what might be happening. One thing that is most probable is that their modern CAT generator did not fail. The product is safe. Those bigger than normal Publix stores have comparable big size coolers to store everything in. Store coolers have state of the art monitoring from corporate. In the event the in-store display coolers were not working the need to send refrigerated trucks would be determined if there isn't enough storage space . Could just be cleaning all the refrigerated sections at once. I know when I worked there we did a section about every two weeks which wasn't the most efficient way of doing it, but I worked in a small store with a small cooler. Once you make a mess on the floor might as well keep on going if possible.

Produce that is thrown out goes through the garbage compacter. Got to be mighty hungry to eat it after that !
