The Cashew Conundrum and The "Toxic" Shell of Secrecy

Just like the raw cashew nut is encased in a shell of caustic urushiol that burns skin on contact, the cashew supply chain is encased in a “shell” of opaque middlemen that burns the planet.

We reach for that bag of roasted cashews because they’re marketed as the ultimate plant-based win—packed with heart-healthy fats, protein, and minerals, a guilt-free snack for vegans, keto enthusiasts, and anyone chasing “clean” eating. Retail giants like Costco, Walmart, and Target proudly display them in bulk bins and private-label packs, often accompanied by corporate sustainability pledges: “committed to 100% sustainable sourcing.”

But peel back the marketing shell, and the Mighty Earth report The Cashew Conundrum (November 2023) exposes a far darker reality. And in February 2026 the situation is even worse

From “Forest Savior” to Green Desert

Côte d’Ivoire is now the world’s top producer and exporter of raw cashew nuts—over 1.2 million tons harvested annually on 1.6 million hectares, an area nearly the size of Hawaii. Global production has exploded from 706,500 tons in 1990 to more than five million tons in 2022, with Africa supplying 58% of the harvest. Much of that boom has come at the direct expense of the country’s remaining dry savanna forests in the north.

Satellite analysis in the report reveals that between 2019 and 2023, some key cashew-growing regions lost up to 25% of their primary forest cover—with the Béré region alone recording a staggering 25.35% loss. Cashew orchards are rapidly replacing diverse woodlands with uniform monocultures the report calls “green deserts”: rows of cashew trees that support almost no other life. The trees are allelopathic—they release chemicals that suppress undergrowth—so even weeds struggle. Pollinator diversity plummets. Endangered species, including chimpanzees near Comoé National Park, lose habitat. Traditional food crops (yam, maize, cassava) are pushed out, turning entire communities into single-crop economies vulnerable to price crashes.

When the 2023 market glut hit, many farmers couldn’t sell their harvest and suddenly couldn’t afford to buy the very staples they no longer grew. The “superfood” on our shelves is literally starving the people who grow it.

The Human Cost Inside the Toxic Shell

The irony deepens in processing. Raw cashews must be roasted to release the kernel from its double shell. That process unleashes cashew nut shell liquid (CNSL)—a caustic oil rich in urushiol, the same compound found in poison ivy. Workers, overwhelmingly women, often remove the kernels by hand with little or no protective gear. Burns, blisters, and rashes are common; many simply endure them because “it will pass.”

Yet when those same nuts reach U.S. shelves, the packaging rarely tells the full story. Most Ivorian raw nuts are shipped to Vietnam or India for processing (78.5% of the crop), then re-exported with vague labels like “product of Vietnam” or “around the world.” Traceability stops at the border. Middlemen and processors obscure the origin, making it nearly impossible for even well-intentioned companies to verify whether their cashews come from recently cleared forest or long-established farms.

Downstream importers and retailers and others continue to stock these nuts while addressing sustainability commitments. But without farm-level traceability and public disclosure of exact sourcing regions, those claims ring hollow. You can’t be “100% sustainable” if you can’t prove the nuts didn’t just burn another 25% of a fragile savanna ecosystem.

The Call to Action

Next time you’re standing in the snack aisle, flip the bag over. If your bag of cashews doesn’t name the specific farm, cooperative, or traceable origin in Côte d’Ivoire—or at minimum provide verifiable proof it’s deforestation-free—ask why.

Demand better. Write to Costco, Walmart, Target, and your favorite brands. Tell them the Mighty Earth 2023 report has shown the cost of secrecy. Tell them consumers won’t accept “plant-based” that destroys forests, displaces food crops, and burns workers’ hands. True sustainability isn’t a slogan on a label—it’s a transparent supply chain that protects both people and planet.

The cashew conundrum is solvable. But only if we crack open the shell of secrecy first. Your next handful of nuts could help decide whether that shell finally breaks—or keeps burning.
