Grocery liquidation is a date business. Food loads typically come from promotions that over-ordered, discontinued flavors and packaging, holiday candy after the holiday, close-dated stock a distribution center could not place in time, and cases damaged in handling. Household goods ride alongside: paper towels, toilet paper, trash bags, laundry detergent, dish soap, cleaning tools and food storage. That household side carries no food date, which is why it often holds up the value of a mixed load when the food is short-dated.
Read the date codes before you read anything else. Except for infant formula, federal law does not require date labels on packaged food, and FDA describes a 'Best if Used By' date as the point when a product is at its best flavor and quality rather than a safety cutoff. That is why past-date shelf-stable grocery can still be sold in many places, and why the date is a pricing input rather than an automatic write-off. Infant formula is the hard exception: FDA rules require a 'use by' date on every container, and formula should not be used after it. Past-date formula is disposal, never stock.
Salvage grocery belongs in this category, not on the general salvage page. It means food whose container or label may have been damaged: dented cans, crushed cartons, water-stained cases, torn labels. Georgia's Department of Agriculture rules treat salvage food as its own class, require food salvagers, salvage food distributors and salvage food auction firms located or operating in Georgia to hold a Food Sales Establishment License, and bar selling cans or packages that lack full labeling. If salvage food is part of your plan, talk to the department before you buy; outside Georgia, check your own state's rules.
Expect shelf-stable product. Refrigerated and frozen food needs an unbroken cold chain that a dock pickup cannot promise on its own, so read any lot with perishables closely and bring a refrigerated vehicle or pass. Some products never belong in these lots: alcohol is prohibited, unopened beer, wine and spirits included, and so are tobacco and vape products. The household side stops short of hazardous materials too, because the prohibited list covers chemicals, pressurised cylinders and loose lithium cells, which keeps out pool chemicals, lighter fluid and propane.
