Workers’ rights issues, from acid hand burns to low pay, make ethical cashew sourcing challenging. We explore the ethics of cashew nuts in more detail to find out what the issues are and what brands are doing about sourcing ethical cashews.
In 2023, a person in Kenya called Daniel Faraja, who lives near a cashew processing plant, noticed his neighbour’s hands looked disfigured. He asked how it had happened. The worker, whose name wasn’t shared, told him:
“I work at the cashew nut processing plant. My hands look like this because of the cashew nuts.”
Faraja said, “It looked so bad and she said she was in pain. I decided to take pictures and share them online because I realised, this person is illiterate, they have not gone to school … they’re not provided with gloves to protect their hands. They are given some temporary gloves, but after 10 to 20 minutes, they’re worn out – they’re not given any others.”
Issues facing cashew workers
Acid hand burns
Cashews are originally encased in a shell. Splitting the shells by hand without protection can result in burns to the skin from the acids between the shell and the nut leading to severe pain and even permanent damage.
Widespread health issues
While acid burns are the risk that’s most unique to cashew workers, a 2024 study in Kerala found that cashew workers commonly experience a range of other health problems. This includes a high risk of musculoskeletal disorders, chronic lung diseases and dermatological problems.
Underpayment
Low pay in the cashew sector has been reported for decades, along with other workers' rights issues. Workers tend to be underpaid and overworked, and, according to Equal Exchange, the cashew industry is marred by a number of problems including “unsafe and exploitative working conditions, poverty-line wages, and ecologically unsustainable supply chains”.
The charity Traidcraft Exchange says the poor working conditions are caused by European buyers including UK supermarkets, who ‘aggressively push down prices’, forcing cashew companies to hire cheap labour.
What are brands doing about these issues?
We haven’t ranked brands that sell whole cashews on their ethics (like we have other products like chocolate and tea, for example).
But we have researched plant based milk and cheese brands, many of which use cashew. It’s likely that only a small amount of the world’s cashews end up in vegan products like these – many are sold and consumed whole or used in sweets, curries and cereals. But here we’ve examined what brands in these sectors are doing to safeguard cashew workers’ rights.
Cashews are the key ingredient in cashew milk, which the brands Plenish, ReRooted and Rude Health sell.
They are also commonly used in vegan cheese – especially for the smaller brands that are making more artisan cheeses (as opposed to waxy, more processed styles like Violife).
Some brands didn’t appear to be taking any steps to mitigate the high risks of cashew worker exploitation. Others had some policy. None had worker-rights specific certifications like Fairtrade, or clear descriptions showing they had a thorough understanding of what the risks were and how their suppliers guarded against them.
Brands who provide no response on cashew issues
Some brands hadn’t published any information about how they safeguard cashew workers’ rights in particular, and didn’t reply to our request for comment. These were:
- Palace Culture
- Plenish (for plant milk)
- Rude Health (for plant milk)
Brands providing some detail on cashew policy
Honestly Tasty: Its website stated that its cashew workers, in Goa, are paid “well above minimum wage, are offered flexible working hours & the necessary equipment to protect against injury”.
Mouse’s Favourite: It says workers in its cashew supply chain are paid above minimum wage and are provided with protective clothing where needed.
ReRooted: ReRooted’s Goan cashew supplier says its employees “are provided with appropriate personal protective equipment to protect against injury” and in one of its photos workers were wearing gloves. In response to our questions, ReRooted started communicating with the supplier about the occupational hazards associated with cashews, which we view as a positive approach.
Tyne Chease: Its website says "Our cashew nuts are only sourced from Fairtrade and SEDEX suppliers." But it wasn’t clear whether it meant Fairtrade International certification, and whether all of its cashews were fair trade.
While these brands are making the right noises, none had thorough discussions about, for example, the issue of hand burns, or clear policies and practices they implemented for all cashew workers to prevent this specifically, with most just referencing PPE.
Organic certification ensures cashews are grown without artificial chemicals, such as pesticides, but we do not consider organic certification to provide assurance regarding workers’ rights.
Several brands use other certifications or auditing standards, but these did not contain specific clauses in relation to cashew harvesting and processing.
What more could brands do to support cashew workers?
For products like chocolate, there are clear standards about what ‘more ethically sourced cocoa’ is – for example it has Fairtrade International or Rainforest Alliance certification or is value-added-at-source.
But there doesn’t seem to be clearly defined standards that are being embraced across the cashew sector, even though international demand for the nut is soaring.
There are, however, some ways brands can source cashews more ethically.
Fairtrade International certified cashews
Fairtrade certified cashews are available to buy in the UK, for example from Oxfam or Tesco.
Fairtrade International certification requires cashew workers to be:
- Adequately protected from the cashew nut liquid.
- Provided with protective garments and oils from the employer.
- The employer should train workers on how to use these protective garments / oils.
- And the employer should monitor to ensure all the above happens.
Engaging with suppliers to see how seriously the issue is taken
Equal Exchange, a Best Buy in our ethical coffee guide, seems also to have a strong approach on cashews.
We asked how it addressed workers’ rights for the cashews it sells. It replied promptly with an explanation from its cashew supplier, called Gebana, in Burkina Faso.
The supplier said their employees protect their hands with cashew oil while working. Cashew oil is a by-product of the production process and is extracted from oily kernels that are not suitable for consumption. They say it acts as a natural antidote to the corrosive liquid from the shells.
“At the end of the day, the workers clean their hands thoroughly with maize flour and lemon juice to remove all traces of the liquid. We have carried out various tests with different types of gloves, but the cashew oil approach has proven to be the most effective method of protection.”
It claims that these practices are used across Gebana’s entire supply chain.
While verifying the effectiveness of these practices is beyond our scope, this seems like a strong approach to cashew workers’ rights issues because it shows:
- The brand has a relationship with its supplier.
- The supplier is aware of the risks in its sector and does not try to obfuscate them.
- They have a realistic narrative explaining how they have tried to deal with the issues.
- Their preferred solution is said to apply for all workers throughout the supplier’s business.
An expanding cashew industry
Demand for this sweet, protein-filled nut (technically not a nut but a type of fruit called a drupe) is soaring. Global cashew yields leapt from 706,500 tons to 3.9 million tons between 1990 and 2018, reaching more than five million tons in 2022.
Where do cashews come from?
Cashews are native to Brazil, but are now grown widely across west Africa, India and south east Asia. Half of the world’s cashews are cultivated in west Africa, yet due to a lack of processing (shelling) capacities, African producers still export most of their crop as in-shell cashew nuts to Vietnam and India. Around 80% are processed in those two countries, before approximately 35% of those nuts are re-exported to consumers in Europe.
Environmental issues with cashews
A 2024 report by Might Earth highlighted the growing issue of cashew monocultures in West Africa, particularly in Côte d’Ivoire. Monocultures are eradicating the region’s remaining areas of dryland savanna forest, replacing them with hundreds of square kilometres of “green deserts”.
This loss of biodiversity comes with a human cost. The replacement of traditional food crops with cashews, which are primarily exported, leaves the country vulnerable to market shocks. A 2023 price crash created widespread food insecurity in rural areas, with much of the region now a single crop economy.
Take action on cashew sourcing
If you want to show brands and suppliers that you care about workers rights in this sector, you can deliberately buy from brands with strong sourcing approaches. Or you can reach out to brands that use cashews and ask what measures they have in place – this is a powerful way to encourage brands to make sure they’re taking the issue seriously and try to raise standards in the industry.
