Honey isn’t the only sneaky ingredient you have to worry about when you’re going vegan. Get this: some vegetables sitting in your typical grocery haul aren’t actually vegan by some standards. Sounds absurd, but it’s true. If you’re picturing a world where carrots and tomatoes play dirty, you might want to buckle up. Wait until you hear what’s hiding under the surface of innocent-looking avocados, almonds, and mushrooms. Anyone who cares about animal welfare or wants to keep their diet 100% plant-based should know these facts. It’s the kind of thing I’d chat about with Evelyn at the farmer’s market, scanning the stalls and wondering what’s really behind the labels.
The Definition Dilemma: What Makes a Vegetable Vegan?
Alright, let’s get our terms straight before we open the rabbit hole. Most people picture vegan food as anything plucked from a tree, dug out of the ground, or snipped off a stem—no animal involved, right? But here’s the thing: being "vegan" doesn't just mean avoiding the obvious chunks of meat or cheese. For a lot of us, it’s about dodging anything connected to animal exploitation, suffering, or even just animal "use" in food production. That sneaky fine print actually puts some vegetables on the hot seat.
Some veggies cross the vegan line not because they contain animal bits, but because animals were involved in making them grow or come to your plate. Bees, for example, get roped in to pollinate certain crops by hand, a process called migratory beekeeping. Hives get hauled around in trucks, bees get worked to exhaustion, and some die on the job. Suddenly, that avocado toast isn’t strictly cruelty-free if you follow the strictest vegan philosophy.
This debate isn’t just random internet chatter. The Vegan Society, based not too far from me in Brighton, calls for avoiding animal exploitation wherever "practicable and possible." Interpret that as you will: for some, it means skipping these veggies. The mainstream vegan diet often shrugs off these technicalities, but plenty of ethical eaters draw the line tighter. So, what’s a mindful shopper to do? The next sections get into the details—names, facts, the full grit.
The Shock List: Vegetables and Crops That Aren't Vegan
Grab your shopping bags—things are about to get weird. Here are a handful of vegetables (and fruits) that regularly appear on lists of "not-actually-vegan" produce. The reason always comes back to how they’re grown, not what’s in them. It all starts with those superstar pollinators.
- Almonds: California’s massive almond farms use migratory bees trucked in from all over. In 2022, more than 88% of all commercial bees in the U.S. were used just for almond pollination. The stress on bees is intense. Queen bees die, hives collapse, and the process has even been blamed for contaminating hives with pesticides and pathogens. Definitely not bee-friendly.
- Avocados: The darling of brunch tables everywhere, but commercial avocados also rely on migratory pollination. Bees get overworked, and avocado monocultures are harsh on the environment (and local animals) too. That dreamy guacamole comes with a price.
- Butternut Squash: Many big squash growers import bees to boost yields, since natural pollinators can’t keep up with farm demand. The result? More bee suffering, same as above.
- Blueberries, Cherries, Apples, and Melons: These fruits are big fans of commercial bee pollination. Every year, billions of bees hit the road to work these fields. The travel alone messes with their health, plus pesticides make it worse.
- Mushrooms: Okay, these don’t need bees, but here’s a twist—many conventionally grown mushrooms use animal-based fertilizers, like manure. Some vegans will only eat mushrooms grown using vegan compost or certified vegan sources.
That’s just the headline list. If you’re thinking about going super strict, you might want to start asking your local market where and how the produce is grown. Remember, the line between vegan and non-vegan here is more about ethics than chemistry.

How Do Animal Products End Up in Vegetable Production?
Ever wonder exactly how animal products sneak into veggie farming? It’s not always about bees. Sometimes, it’s what’s in the dirt itself. Most commercial farming still leans hard on animal-derived fertilizers—think manure, bone meal, blood meal, and fish emulsion. Even those tomatoes and lettuces stacked high in the grocery could have been grown in soil rich with cow or chicken byproducts.
When you get into organic farming, the plot thickens. Organic growers lean heavily on composted animal manures since synthetic fertilizers are banned. That’s good for soil health, but not so good if you want zero animal involvement. Vegan organic farms (sometimes called "veganic farms") instead use plant-based compost, green manure, or mineral blends. These are growing in number, but you still have to hunt for them. There’s no UK law requiring veganic labeling, though some certifications—like Biocyclic Vegan—exist for those who want to seek them out.
Mushrooms deserve an extra shout. Farmed mushrooms often grow on substrates mixed with animal byproducts. Oyster mushrooms might be on vegan menus everywhere, but only some growers steer clear of animal waste in the growing medium. Lettuce, strawberries, even potatoes... any could use animal-based additives. Want a conversation starter on your next picnic? Ask your mates if they know what blood meal is.
Vegetable/Fruit | Typical Animal Involvement | Vegan Alternatives Available? |
---|---|---|
Almond | Migratory bee pollination | Rare; Wild-pollinated or from small farms only |
Avocado | Migratory bee pollination | Occasionally; Wild or local small farms |
Mushroom | Grown on animal manure substrate | Yes, from plant-based substrate growers |
Lettuce | Manure-based fertiliser | Sometimes; Check for veganic growers |
Is It Even Possible to Eat 100% Vegan Vegetables?
The short answer? It’s almost impossible—at least if you want to do all your shopping from standard supermarkets. Large-scale agriculture is built around efficiency, not animal kindness. That means animal inputs are everywhere, from bee labor to animal-based fertilizer to pest management. Even if you grow veggies in your backyard, you’ll run into dilemmas: do you squash pests by hand, spray soap, or risk the odd snail surviving? There’s always a tradeoff between purity and practicality.
But don’t beat yourself up. The Vegan Society, and lots of ethicists, argue that "possible and practicable" is the line. Most strict vegans focus their attention where the animal suffering is clearest—meat, dairy, eggs, honey, leather. For produce, it usually comes down to risk versus reward. If you’re worried about the footprint of your salad, there are steps you can take. Ask your local greengrocer how things are grown. Buy from small, organic, or veganic farms. Or, grow your own if you’re up for a bit of muddy work.
Real talk—every British summer, I try to grow tomatoes in my Brighton yard with minimal pest control and zero animal oddities. Sometimes it works, sometimes it’s a buffet for aphids and squirrels. But when you sit down with your own produce—even just herbs on a windowsill—it feels different. You’re closer to the process, and with less mystery about what’s behind the curtain.

Tips for Vegans Who Want Truly Plant-Based Produce
Feeling overwhelmed? Here are some action steps if you’re on a mission to make your veg as vegan as possible:
- Look for "veganic" or Biocyclic Vegan-certified produce at health food shops and farmers’ markets.
- Ask questions! Grill your supplier about fertilization, pest control, and pollination methods.
- Support small, local, and organic farms; they’re more likely to avoid industrial-scale bee and animal product use.
- Grow your own. Even starting with a pot of herbs or strawberries means you control the process.
- Take it easy—no one can be perfect. Focus on avoiding the biggest sources of animal suffering first.
- Educate yourself on seasonal, local produce. The less transport and intervention required, the more likely those veggies are to have minimal animal input.
- Connect with vegan communities online or in person. Brighton’s got a wicked veganic gardening group, and there’s probably one near you.
If you’re on the fence about whether this makes veggies "not vegan," remember this: the strictest definition isn’t always the most practical. The goal is progress, not perfection. My wife, Evelyn, always says, "Better imperfect action than perfect intention"—and she’s spot on. Keep the focus on the big picture, but don’t be afraid to ask the awkward questions. That’s how things start to change.
