Donation centers keep strict rules about what they can and cannot accept, and ignoring those rules often means your well-meant drop-off goes straight to the trash. By understanding the specific items that organizations routinely reject, you can protect staff and shoppers, avoid wasting resources, and make sure your donations actually help people instead of creating extra work or risk.
1) Recalled Items
Recalled items are among the first things many donation centers will reject, because they are already flagged as unsafe by the manufacturer or regulators. Goodwill explicitly lists “items that are recalled by the manufacturer” on its not-accepted list, alongside other high-risk categories like baby cribs and certain older tube TVs. Once a recall is issued, the product is supposed to be repaired, destroyed, or returned, not passed along to a new user through a thrift store.
For you as a donor, that means checking recall notices before loading up your car, especially for baby gear, small appliances, and electronics. If a crib, space heater, or blender has been pulled from the market, a donation center cannot legally or ethically resell it. The stakes are high, because reselling recalled items can expose charities to liability and put low-income shoppers at risk of burns, falls, or other injuries.
2) Expired Medications
Expired medications are another category that reputable donation centers will not touch. The Salvation Army’s health and safety protocols state that they do not accept “expired medications or supplements,” because potency and safety cannot be guaranteed once a product is past its labeled date. That rule applies whether you are talking about prescription pills, over-the-counter pain relievers, or herbal capsules that look harmless on the shelf.
From a public health standpoint, the concern is twofold, involving both effectiveness and misuse. Expired antibiotics, for example, may not treat infections properly, while old controlled substances can be diverted or abused. Instead of donating, you are expected to use pharmacy take-back programs or local hazardous waste events that are set up to handle expired medications safely, so they do not end up in landfills or in the hands of someone who should not have them.
3) Dented or Bulging Cans
Dented or bulging cans are a clear red flag for food pantries that follow Feeding America’s safety standards. Those guidelines instruct food banks to reject “canned goods with bulging, dented, or rusted lids,” because those defects can signal broken seals, internal contamination, or the presence of dangerous bacteria. A can that is swollen or badly creased at the seams is treated as potentially unsafe, even if the label looks fine.
When you sort your pantry for donation, you are expected to pull out any cans with deep dents, rust around the lid, or lids that dome upward. The stakes are serious, because compromised cans can harbor Clostridium botulinum, which causes botulism, or other pathogens that thrive in low-oxygen environments. Food banks want to provide reliable nutrition, not gamble with foodborne illness among people who may already have limited access to medical care.
4) Old or Stained Mattresses
Old or stained mattresses are a frequent source of confusion, but many building-material resale outlets have drawn a firm line. Habitat for Humanity ReStores, which accept donations and sell a constantly changing inventory of diverse, high-quality merchandise to the public, decline “mattresses over 10 years old or with stains” under their quality control policy. Their focus is on items that can be safely reused in homes, not on bedding that might harbor allergens or pests.
For donors, that means a sagging or visibly soiled mattress is not a charitable gift, it is a disposal problem. Stains can indicate bodily fluids, mold, or bedbugs, all of which pose health risks and can spread through a warehouse. By limiting mattresses to newer, clean pieces, Habitat for Humanity ReStores protect staff, volunteers, and shoppers while keeping their inventory appealing enough to generate revenue for housing projects.
5) Damaged Electronics
Damaged electronics are another category that thrift stores routinely reject, even when the item looks expensive. Consumer Reports notes that stores like Goodwill turn away “electronics without cords or with visible damage,” because they cannot verify that the devices are safe or functional. A flat-screen TV with a cracked screen, a microwave with a broken door latch, or a laptop missing its power adapter all fall into this no-go zone.
From the store’s perspective, accepting broken electronics creates e-waste they must pay to recycle and exposes them to fire or shock hazards if something slips onto the sales floor. For you, the takeaway is to test electronics before donating and include all necessary cords and accessories. If an item sparks, overheats, or has exposed wiring, it belongs in an electronics recycling program, not in a donation bin where an unsuspecting buyer might plug it in at home.
6) Recent Travel to Malaria Areas
Recent travel to malaria-endemic areas can temporarily disqualify you from donating blood, even if you feel healthy. The American Red Cross blood donation centers follow CDC-linked guidelines that reject donors who have “traveled to malaria-endemic areas within the last year.” The concern is that Plasmodium parasites can remain in the bloodstream without obvious symptoms, then be transmitted to a transfusion recipient with a weakened immune system.
For potential donors, this rule can be frustrating, but it is a key safeguard for the blood supply. If you have visited parts of sub-Saharan Africa, South Asia, or other regions where malaria is present, you are expected to wait out the full deferral period before giving blood again. That waiting period helps protect patients undergoing surgery, chemotherapy, or emergency treatment, who rely on donated blood being as safe and predictable as possible.
7) Used Undergarments
Used undergarments and swimwear are almost always on the “do not donate” list for clothing-focused charities. Salvation Army thrift stores spell this out in their hygiene policy, stating that they will not take “used undergarments or swimwear.” Even if items are freshly laundered, the intimate nature of bras, underwear, and bathing suits makes them difficult to inspect and resell in a way that feels sanitary to shoppers.
For you, that means worn underwear should be discarded rather than donated, while new-in-package items may be accepted if clearly labeled and unopened. The stakes are not only about germs but also about dignity and customer expectations. People shopping secondhand still want clothing that feels clean and respectful, and donation centers must maintain that standard to keep their stores welcoming and their reputations strong in the community.
8) Home-Canned Foods
Home-canned foods, no matter how lovingly prepared, are not accepted by most food pantries linked to Feeding America. Their partner network safety brief explains that pantries reject “home-canned foods due to botulism risk,” because there is no reliable way to verify that each jar was processed at the correct temperature and pressure. Even a single improperly sealed jar of green beans or salsa can carry spores that produce a deadly toxin.
For donors, that means sticking to commercially canned and packaged foods with intact factory seals. While it may feel wasteful to keep or discard jars from your own kitchen, food banks must apply uniform standards that protect every client. The broader implication is that food safety rules prioritize consistency over sentiment, ensuring that donated items meet the same baseline as products on a grocery store shelf.
9) Automotive Fluids
Automotive fluids are another category that charities refuse, even if the container is unopened. Goodwill’s hazardous materials policy states that it rejects “automotive fluids like oil or antifreeze,” grouping them with other items that pose environmental hazards. These liquids are flammable, toxic, or both, and they require specialized handling that a typical thrift store is not equipped to provide.
From your perspective, that means used motor oil, transmission fluid, and coolant should go to municipal hazardous waste collection sites, not the donation dock. If such products leak in a truck or warehouse, they can contaminate other donations and create cleanup costs that eat into charitable budgets. The rule reflects a broader trend in donation policies, where anything regulated as hazardous waste is kept out of the resale stream entirely.
10) Open Pet Food Bags
Open pet food bags, even if they are nearly full, are typically turned away by animal shelters that follow ASPCA guidance. Those guidelines explain that local shelters decline “open bags of pet food” to prevent spoilage and contamination. Once a factory seal is broken, there is no way to guarantee that the kibble or canned food has been stored correctly or kept free from pests and moisture.
For pet owners hoping to help, that means only sealed, unexpired pet food is appropriate for donation. Open bags can attract rodents or insects in storage areas and may harbor mold that is not visible at first glance. The stakes are high for shelters, which care for animals with varying health conditions and cannot risk feeding them compromised food that could trigger illness, recalls, or veterinary bills they are not funded to cover.
11) Moldy Books
Moldy books are another item that community centers and literacy programs will not accept, no matter how rare or beloved the title. United Way community centers, following their library donation standards, reject “books with mold or water damage” because those volumes can spread spores to other materials and degrade quickly on the shelf. Water stains, warped pages, and a musty odor are all signs that a book has crossed the line from gently used to unusable.
For donors, the practical step is to inspect your boxes before drop-off and recycle any books that show visible mold or severe warping. Allowing contaminated items into a shared collection can trigger respiratory issues for staff and visitors, especially those with asthma or allergies. By enforcing this rule, community centers protect both their existing inventory and the indoor air quality of reading rooms and classrooms.
12) Chemically Treated Fabrics
Chemically treated fabrics, particularly those containing hazardous flame-retardant chemicals, are increasingly being screened out by clothing donation centers. FDA consumer updates note that centers affiliated with Planet Aid reject “items treated with hazardous chemicals, such as certain flame-retardant fabrics,” because of potential health risks. These treatments can involve substances linked to endocrine disruption or other long-term effects, especially when worn close to the skin.
For you, that means older children’s pajamas, upholstered items, or workwear labeled with specific chemical treatments may not be welcome in donation bins. The broader trend reflects growing concern about toxic exposures in everyday textiles and a shift toward more cautious intake policies. By refusing these items, donation centers aim to protect vulnerable populations who rely on secondhand clothing, ensuring that affordability does not come at the cost of hidden chemical hazards.
