A package of muffins reaches its sell by date. A carton of eggs is approaching the date printed on the lid. Produce has a few blemishes but is still usable. What happens next depends on the food, its condition and the policies of the store handling it.
Supermarkets have several options for food that doesn't sell at full price. They may mark it down, donate it, redirect it for animal feed or compost it. Some products still end up in the trash, particularly when they're spoiled, damaged, recalled or no longer safe to handle. Store policies and local donation arrangements can also affect what's possible.
Costco's bakery is known for selling large packages, but those products still have a limited shelf life. Costco has systems for diverting eligible unsold bakery goods, including donation programs and other waste reduction channels. The exact destination can depend on a warehouse's local partnerships and whether the food remains suitable for donation.
That last detail matters. A sell by date doesn't necessarily mean a product suddenly became unsafe, but a store still has to consider freshness standards, storage conditions and the amount of time needed to collect and distribute a donation. If an item can't be donated, some businesses may have alternatives such as composting, animal feed or energy recovery.
In other words, there isn't always one answer for every leftover muffin. The broader goal is to find the most useful responsible destination available before disposal becomes necessary.
Aldi also uses more than one approach. The grocer marks down some products as they approach the end of their selling window. This can help food reach a customer while it's still in good condition, rather than waiting until donation or disposal is the only option.
Food that remains safe but can't be sold may also be donated through community partners. Products that aren't suitable for people may enter another diversion stream where local services are available. As with Costco, practices can differ by location because stores rely on regional infrastructure, pickup schedules and nonprofit capacity.
Markdowns are an especially practical first step. Shoppers save money, stores recover part of the product's cost and edible food is more likely to be used. The catch is that a discount is only valuable if the buyer has a realistic plan for the food. A half-price package that spoils untouched is still wasted money.
Many grocers combine inventory planning, discounts, donations and waste diversion, but not every item can be rescued. Food safety rules, damaged packaging, temperature changes and contamination concerns can make donation inappropriate. Smaller stores may also have fewer nonprofit pickups or composting options nearby.
That helps explain why reports of supermarket donations and reports of discarded food can both be true. A store might donate bread, mark down dairy products and discard a damaged refrigerated item on the same day. The important question isn't whether a chain has one universal solution. It's how consistently each location prevents excess inventory and chooses the best available option for food that remains.
Households face a smaller version of the same decision. One common mistake is treating every printed date as an automatic instruction to throw food away.
The wording makes a difference. A sell by date primarily helps a store manage inventory. A best if used by date generally points to the period when a product should have its preferred flavor or texture. Neither phrase necessarily means the food becomes unsafe the next morning. Storage history, package condition and the type of food still matter, and official food safety advice should take priority for highly perishable products.
A few simple habits can make those distinctions useful. Keep a clearly visible "use first" area in the refrigerator. Freeze meat, bread and other suitable foods before quality declines. Plan one flexible meal each week around ingredients that need attention. When shopping clearance sections, buy only what you can cook or freeze promptly.
Supermarkets operate on a much larger scale, but the basic principle works at home too: inspect what you have, understand the label and choose the most useful next step before good food goes to waste.
