How to Prevent Accidental Poisoning at Home

Most accidental poisonings happen at home, and the vast majority are preventable with a few straightforward habits. In 2024, U.S. poison centers managed hundreds of thousands of exposures involving everyday items: cleaning products, pain medications, cosmetics, and prescription drugs. Whether you’re childproofing a house, keeping pets safe, or just want to be smarter about what’s under your sink, the strategies below cover the most common risks and how to eliminate them.

The Substances That Cause the Most Poisonings

For children five and under, the top culprits are household cleaning products (87,031 cases in 2024), pain relievers like acetaminophen and ibuprofen (78,993 cases), and cosmetics or personal care products (78,721 cases). Foreign objects, toys, and dietary supplements round out the top five. Young kids are especially vulnerable because they explore by putting things in their mouths, and many dangerous products come in colorful packaging that looks appealing.

For adults, pain medications lead the list at over 132,000 exposures in 2024, followed by heart medications, antidepressants, and sedatives or sleep aids. Adult poisonings often involve medication mix-ups, accidental double doses, or confusion between similar-looking pills.

Medication Safety at Home

The simplest rule is also the most effective: put medications away immediately after every use, with the safety cap locked, in a location children cannot reach or see. A surprising number of pediatric poisonings happen when a bottle is left on a counter for just a few minutes.

Beyond storage, read the label every single time. Turn on a light if you’re taking something at night, and wear your glasses if you need them. These small steps prevent the kind of errors that lead adults to take the wrong pill or the wrong dose. Check active ingredients in both prescription and over-the-counter products, because many contain the same compounds. Taking a cold medicine and a headache tablet that both contain acetaminophen, for example, can push you past a safe dose without realizing it.

For disposal, don’t leave expired or unused medications sitting in a cabinet. Many pharmacies and police departments have take-back programs. If you flush or trash medications, check the FDA’s guidelines for which ones are safe to dispose of at home.

Cleaning Products and Chemicals

Household cleaners are the single largest category of childhood poisoning exposures. Store all cleaning products in a locked cabinet or on a high shelf, never under the sink where a toddler can open a door. Keep products in their original containers so you always know what’s inside and can read the safety instructions if something goes wrong.

Never mix cleaning products. Bleach combined with ammonia or with acidic cleaners produces toxic fumes that can cause serious respiratory damage. If you’re cleaning in an enclosed space like a bathroom, open a window or run a fan.

Carbon Monoxide Protection

Carbon monoxide is odorless and colorless, which makes it impossible to detect without an alarm. Install CO detectors on every level of your home and in a central location outside each sleeping area. Follow the manufacturer’s instructions for mounting height and placement, and replace batteries at least once a year.

Common sources of carbon monoxide include gas furnaces, water heaters, fireplaces, attached garages, and portable generators. Never run a generator indoors or in a garage, even with the door open. Have fuel-burning appliances inspected annually.

Lead Exposure in Older Homes

If your home was built before 1978, it likely contains lead-based paint. The danger isn’t the paint itself when it’s in good condition. It’s the dust and chips that form when painted surfaces deteriorate or get disturbed during renovation. According to the EPA, the most important steps are keeping all painted surfaces in good condition and cleaning frequently with a wet mop or damp cloth. Dry sweeping and dusting just spreads lead particles around.

Remove your shoes before entering the home to avoid tracking in lead-contaminated soil, and place mats at every entry point, inside and out. If you’re planning any renovation work on pre-1978 surfaces, hire a contractor certified in lead-safe work practices.

Safe Food Handling Temperatures

Food poisoning is one of the most common forms of poisoning, and a food thermometer is your best defense. The USDA’s minimum internal temperatures are:

  • Beef, pork, veal, and lamb (steaks, chops, roasts): 145°F, then rest for at least 3 minutes
  • Ground meats (beef, pork, veal, lamb): 160°F
  • All poultry (whole birds, breasts, thighs, wings, ground poultry): 165°F
  • Ham (fresh or uncooked): 145°F, then rest for at least 3 minutes

Beyond cooking temps, keep raw meat separate from ready-to-eat foods, refrigerate leftovers within two hours (one hour if the temperature outside is above 90°F), and wash hands thoroughly before and after handling raw meat.

Toxic Plants Indoors and Out

Several popular houseplants can cause reactions ranging from mouth irritation to serious organ damage if ingested by children or pets. Among the most common toxic varieties: calla lily, caladium, Chinese evergreen, peace lily (spathiphyllum), ZZ plant, daffodil, azalea, amaryllis, and yew, which often appears in holiday greenery. Schefflera and anthurium are also widely sold and toxic.

If you have young children or pets that chew on plants, either remove toxic species or place them completely out of reach. When buying new plants, check toxicity before bringing them home.

Antifreeze and Garage Chemicals

Antifreeze contains ethylene glycol, a sweet-tasting compound that’s extremely dangerous to children and pets. Even small amounts can cause kidney failure as the body breaks the chemical down into toxic byproducts. Dogs and cats are drawn to puddles of antifreeze because of the taste.

Store antifreeze in its original container in a locked area. Clean up any spills or leaks immediately, and never pour antifreeze onto the ground or into storm drains, where animals can find it. Some manufacturers sell “pet-safe” antifreeze made with propylene glycol, which is significantly less toxic, though it should still be stored carefully.

What to Do If a Poisoning Happens

If someone swallows a potentially toxic substance and is conscious and alert, call Poison Control at 1-800-222-1222. This free, confidential hotline connects you with toxicology experts 24 hours a day, 365 days a year, anywhere in the United States. They’ll walk you through exactly what to do based on the substance and amount involved.

If the person is unconscious, not breathing, or having seizures, call 911 immediately.

One critical point: do not induce vomiting. Syrup of ipecac was once a medicine-cabinet staple, but medical guidelines now advise against using it because it can cause more harm than good. Vomiting a corrosive substance, for instance, burns the throat a second time on the way back up. Let Poison Control or emergency responders guide the treatment.
