Fall’s Big Debate Settled! Is It OK to Eat an Apple Right Off the Tree, or Do You Need to Wash It First?
When I took my kids strawberry picking over the summer, more of the juicy red fruits ended up in their mouths (and down their shirts) than in their buckets. So now, as I prepare to take them apple picking this fall, I’m fully expecting a similar experience. I mean, those apples are delicious, and even better, the kids are eating something healthy.
But should I be putting a stop to this mid-picking fruit gorging? Yes, everyone does it, but as with so many things, that doesn’t mean it’s a good idea! I don’t want to be a party pooper here, but I have to wonder if it’s actually safe or healthy to eat an apple straight off the tree. After all, I always wash my apples when I bring them home from the supermarket. Is washing equally important when you’re getting your fruit straight from the source?
To find out, I spoke with Jessica Brantley-Lopez, a registered dietitian nutritionist who also coaches organizations on food safety and sanitation. Read on to find out the answer to this fall debate—and decide if you’re willing to take the risk.

Is it OK to eat an apple right off the tree when apple picking?
Technically, no, it’s not ideal. “Even though [that apple] may look clean, it has been growing outdoors and can be exposed to bacteria from animals, soil, water or even people handling the fruit,” Brantley-Lopez says. “If you’re at an orchard, there may also have been agricultural sprays used on the trees.” Yep, she’s talking about pesticides. (More on that below.)
The best-case scenario? You consume something yucky. The worst case, of course, is that you get sick. “You just don’t know what that apple may have been exposed to,” she explains. “That’s why rinsing it first is such an easy step to reduce your risk.”
What icky things might you find on an apple?
Since apples are growing outdoors, there are quite a few things that can make their way onto the surface of the fruit. Here are the most likely culprits.
Dirt
Sure, kids may eat dirt from time to time. But do we really want them to eat it if we can prevent it? And do we want to eat it ourselves? I’d guess that the answer to both those questions is no. According to the National Library of Medicine, there’s nothing inherently poisonous or dangerous about dirt itself, but it can contain chemicals, fertilizers, parasites, fungus or toxins that could make you ill, and you might not be able to see those things on the surface of the apple.
Animal contamination
There could be bird poop or schmutz from other animals on the apples, says Brantley-Lopez. And any contamination that comes from animals, even if it’s only a little bit, could expose you to illness-causing bacteria. When it comes to bird poop, in particular, there’s a risk of contracting psittacosis, a respiratory infection. You don’t actually need to consume the bird poop to catch this bug; it’s most commonly spread by inhaling dust that contains dried bird droppings. People who have a lot of contact with birds, like poultry workers, bird owners or pet-shop employees, are at a greater risk, but you could still get it if you pick and bite into an apple that has some of this dust on it.
Other bacteria
Bacteria from animal contamination isn’t the only thing you need to worry about. There could be other bacteria growing on the apple, transferred from the soil or water while the apple was growing. The most harmful one is listeria, which is generally found near the stem or on the bottom of the apple, per Washington State University. Listeria can cause unpleasant gastrointestinal symptoms, according to the Mayo Clinic, but it can be much more serious for pregnant people and folks with weakened immune systems.
There was a listeria outbreak in 2014 linked to commercially produced caramel apples; the caramel coating created an ideal environment for the bacteria to grow. And while there haven’t been any outbreaks tied to fresh apples recently, it’s still something you should be aware of.
Germs from other people’s hands
“At a busy apple orchard, you don’t know how many people may have touched that apple before you picked it,” says Brantley-Lopez. You also don’t know how recently they washed their hands. Apples are not the same as countertops or doorknobs—after all, they have a waxy surface and a certain level of moisture—but the germs that cause respiratory infections, the flu and norovirus, for instance, may survive for a few hours on the fruit’s surface if someone with one of these illnesses touched it but decided not to pick it. Then, if you ate it before washing it … well, you know how that story ends.
Pesticide residue
“Depending on the orchard, there could also be pesticide residue or other agricultural sprays on the surface of the apple,” Brantley-Lopez says. According to a 2025 report from the USDA’s National Agricultural Statistics Service, 77% of apple growers use insecticides and 75% use fungicides, so there’s a very high chance that your local orchard is using some sort of spray to protect its apples from bugs and diseases.
Eating one apple with some pesticides on it likely won’t cause any immediate harm, but long-term exposure has been associated with diseases like cancer and neurological disorders.
Bugs
There could be an ant or another small bug crawling across the surface of the apple. Chances are, you’ll notice this and flick it off, but what happens if you’re distracted by your kids and you forget to look before you take a bite? Just … yuck.
Is it safe to eat apples straight off the tree at some orchards?
Perhaps if the orchard only uses organic farming practices or doesn’t use pesticides? Unfortunately, that’s also a no. “Organic versus non-organic doesn’t really change the risk of bacterial contamination,” says Brantley-Lopez. “An organic apple can still be exposed to animals, soil, water and people handling it. And organic doesn’t always mean pesticide-free. Some approved sprays can still be used.”
Can you actually get sick from eating an apple off a tree?
Yes. “Depending on what may be on the apple, you could experience anything from mild stomach upset, nausea or diarrhea to a more serious foodborne illness,” Brantley-Lopez says. “Some bacterial infections can become severe enough to require a hospital visit.”
I mentioned some of the possible infections you could catch earlier, but what it boils down to is that you just don’t know what chemicals or contamination the apple has been exposed to when you pick it. As a result, it’s hard to say how large of a risk you’re taking by munching on it without washing it.
Is there a proper way to clean it off in the orchard so it’s safe?
Yep—the old rinse ‘n’ rub is enough to reduce dirt and bacteria on the surface of the apple, says Brantley-Lopez. “Many orchards have washing stations available, sometimes right in the picking area,” she adds. “And you don’t need soap or a special produce wash. Plain running water is best.” If you’re apple picking with kids and already toting a bag with you, consider bringing a bottle of water or a small spray bottle so you can rinse off the apples before eating them.
That said, this advice applies to unbroken, unbruised apples that are still hanging from the tree. “If an apple has fallen on the ground, check it carefully for bruising, cracks or other damage,” Brantley-Lopez says. “A fallen apple isn’t automatically bad, but once the skin is damaged, there is more opportunity for contamination.” And if the apple actually looks bad, even a little, it’s best to just leave it there.
Do you also need to clean apples from the supermarket?
Yes, the same rules apply to apples from the grocery store. “Even if apples were rinsed during packing, they can still pick up dirt or bacteria during transportation, handling or at the grocery store,” says Brantley-Lopez.
That goes for apples you plan to peel or cook with too. “Cutting or peeling can transfer bacteria from the outside of the apple to the inside,” she explains, so it’s still important to wash it.
The bottom line: At the very least, splash some water on your apples before they make it to your mouth or your kids’ mouths.
