Workers sorting through donated items at a Goodwill store in Ellsworth, Maine, found what appeared to be a hand grenade on a Tuesday morning, and the discovery emptied the building, brought firefighters and police to the scene, and required a state bomb disposal specialist to determine the device was harmless.
The Ellsworth Police Department confirmed the situation was safely resolved after a specialist from the Maine State Police Explosive Ordnance Disposal Team examined the object and identified it as the shell of a grenade with its explosive core removed. A sweep of surrounding donations turned up no other suspicious items.
Nobody was hurt. But the incident is a sharp reminder that charity donation bins are not dumpsters, and that the people who staff these stores bear the consequences when donors treat them that way. The US Sun reported that Goodwill locations across Maine and New Hampshire maintain a list of 36 items banned from donation, rules that exist, the report noted, "to protect both staff and shoppers, and to avoid incidents like Tuesday's scare."
Staff at the Ellsworth branch spotted the suspected device while sorting through a pile of donations. They called police immediately. Officers ordered an evacuation, and emergency crews rushed to the scene.
Firefighters and officers cleared the building and established a safety perimeter around the store. Bomb experts were called in. The wait ended when the Maine State Police Explosive Ordnance Disposal Team specialist arrived, examined the object, and confirmed it posed no threat, it was an inert grenade shell, nothing more.
The Ellsworth Police Department said the situation was safely resolved. No arrests were reported. No one has been publicly identified as the donor.
The grenade scare underscores a practical problem that thrift-store employees deal with constantly: people dropping off items that are dangerous, illegal, or simply unusable. Goodwill locations in Maine and New Hampshire ban 36 categories of items from donation, and the list goes well beyond weapons and ammunition.
Among the banned items the report identified: pillows, mattresses, box springs, car seats, cribs, helmets, and other safety equipment that may no longer meet current standards. Hazardous materials, including paints, solvents, and chemicals, are also prohibited. So are large appliances, building materials, and encyclopedias, items that cost more to handle and dispose of than they could ever generate in resale revenue.
Weapons and ammunition, unsurprisingly, are on the list. But the Ellsworth incident shows that even a hollow, inert shell can trigger a full emergency response. That response costs taxpayer money. It pulls police, firefighters, and bomb-disposal specialists away from other duties. And it puts Goodwill employees, many of whom work for modest wages, in the position of discovering potential ordnance mixed in with old sweaters and kitchen gadgets.
Major retailers have been tightening their own policies around what customers can return or bring into stores. Walmart's return policy now bars more than 30 items from ever being brought back, reflecting a broader trend of retailers drawing harder lines on what they will and will not accept.
Goodwill stores across the country have reported finding firearms, ammunition, and even explosive devices among donated goods. The Ellsworth branch is not the first to call in a bomb squad, and it almost certainly will not be the last.
The problem is partly one of carelessness. People clean out garages, attics, and the belongings of deceased relatives. They bag everything up and drop it at the nearest donation center without checking what's inside. In some cases, the donor may not even know a grenade shell, or something worse, is mixed in with the household clutter.
But carelessness has consequences. Every evacuation disrupts business, frightens employees and shoppers, and demands a public-safety response. Target has similarly tightened what shoppers can return, part of a retail-wide reckoning with the costs that lax policies impose on workers and other customers.
The Ellsworth Police Department has not said whether it is investigating the donation or pursuing charges. Open questions remain: Who brought the grenade shell in? Did they know what they were donating? And does Maine law provide any penalty for dropping off prohibited or dangerous items at a charity store?
Goodwill is in the middle of a significant expansion. The organization is targeting 100 new stores as part of a 2026 growth plan, which means more locations, more donation drop-offs, and, unless donor behavior changes, more chances for dangerous items to slip through.
More stores means more front-line workers sorting through bags and boxes with no idea what's inside. The 36-item banned list exists for a reason, but enforcement relies almost entirely on the honor system. Goodwill cannot inspect every bag before it crosses the threshold. Staff discover prohibited items only after they start sorting, sometimes, as in Ellsworth, with alarming results.
Retail environments increasingly require police involvement for issues that range from shoplifting to safety threats. A recent case in Arizona involved a law enforcement officer facing felony shoplifting charges tied to an alleged scheme at a Walmart, illustrating how retail-related police calls have become a fixture of modern store operations.
The costs of these incidents land on local taxpayers and on the stores themselves. Goodwill operates as a nonprofit, and its mission depends on donated goods that can actually be resold. When donors ignore the rules, whether out of ignorance or indifference, the organization absorbs the cost of disposal, and sometimes the cost of an emergency response.
Goodwill's banned-item policies are publicly available, and the organization asks donors to check before they drop off. The 36 prohibited categories in Maine and New Hampshire cover a wide range: from the obviously dangerous (weapons, ammunition, hazardous chemicals) to the less obvious (pillows, outdated car seats, encyclopedias, building materials).
The common thread is liability and safety. Items that could injure a worker, endanger a shopper, or expose the organization to legal risk are off the list. Retailers of all kinds face growing legal exposure from policies that fail to protect employees and customers, and Goodwill is no exception.
The Ellsworth grenade turned out to be hollow. The next one might not be. And the workers who open those bags deserve better than to find out the hard way.
When charity depends on the good faith of strangers, the least those strangers can do is read the list.
