i worked for 3 different grocery stores, and i was variously a stocker, bagboy, deli service, maintenance and cashier.
Food Lion's misdeeds were horrifying, but only unexpected in their order of magnitude, not their classification.
relabeling old shit with new expiration dates? yep, ordered to do so frequently
turning expired meat into "gourmet selections" by adding a shake of mesquite seasoning or adobo spice? yeah, common as dirt.
using produce which should be discarded in prepackaged salads? please. that was Day One.
improper storage of "product" in a manner which guarantees spoilage, then covering the spoilage with "marinades"? shit, i could tell you horror stories.
Food Lion just took it to revolting extremes.
