Greenpeace finds over 100 pesticides in Britain's traditional Sunday roast vegetables.

A traditional Sunday roast dinner in Britain may soon face scrutiny after researchers identified over 100 hazardous chemicals within these staple vegetables. Scientists from Greenpeace conducted an investigation revealing that common ingredients like onions and leeks contain the highest concentrations of dangerous pesticide residues. These specific vegetables were found to harbor 43 distinct chemical compounds during the testing period covering 2023 and 2024. Carrots and parsnips followed closely behind with 40 different pesticides detected on their surfaces. Other frequently consumed items such as peas, potatoes, swede, and turnips also showed significant levels of chemical treatment. Even strawberries, often served as a dessert, contained 42 separate pesticide types according to the analysis. Nina Schrank, a senior campaigner at Greenpeace UK, noted that while this meal feels natural, it relies on an astonishing mixture of synthetic chemicals. The data confirmed that 102 unique pesticides were applied to these crops either in the field or during storage over the last two years. Seven of these identified substances have already been banned in the European Union due to links with cancer and harm to bees. Officials maintain that current maximum residue levels are set well below safety thresholds for both domestic and imported food. However, campaigners argue these limits ignore other exposure sources like drinking water and plastic packaging. Greenpeace further warns that intensive farming practices are endangering public health and British wildlife through the use of highly hazardous pesticides. Many of these chemicals are classified as PFAS, known as forever chemicals because they persist in the environment for centuries. Ms Schrank stated that the countryside is being drenched in pesticides with devastating consequences for bees, birds, rivers, and soil. Fields once full of wildlife are falling silent while agrochemical companies accumulate profits and farmers remain trapped in a cycle of dependency.

Reducing pesticide reliance does not compromise food security; it strengthens it."

Ms Schrank argues that while farmers confront immense pressure from soaring costs, climate shocks, and unstable markets, many are demonstrating a viable alternative by cutting chemical inputs and adopting nature-friendly methods. The Government's Pesticides Action Plan targets a 10 per cent reduction in pesticide use by 2030. Official data confirms that the total weight of pesticides applied to UK arable crops fell by 25 per cent between 2018 and 2024.

Greenpeace contends that ministers must commit to halving pesticide use by 2030 to fulfill promises regarding nature restoration and food security. The group calls for an 80 per cent reduction by 2040, adequate funding to help farmers decrease dependence on chemical inputs, and stricter restrictions on pesticide application in public spaces and private homes.

Martin Lines, chief executive of the Nature Friendly Farming Network (NFFN), stated: "Many people will doubtless be shocked to learn how extensive pesticide use is within our conventional farming system, but it doesn't have to be this way." He noted that supporting farmers through this transition can significantly drive down pesticide use, yet many producers remain dependent on chemicals due to decades of government policy and supply chain pressures. "We need stronger support, regulation and accountability across the whole system to take the pressure off farmers to produce more and more food from their land, and instead support them to deliver food, nature protection and climate mitigation, all at the same time," he said.

Dale Vince, environment campaigner and founder of Ecotricity, remarked: "An incredible finding – never mind the roast dinner – our fruit and veg is polluted with over 100 pesticides." He described industrial farming as out of control, emphasizing that while these chemicals are toxic and used for their effects, they harm both insects and humans and should not enter the food chain.

An Environment Department (Defra) spokesperson responded: "We place strict limits on pesticide residue levels in food, which are set after rigorous risk assessments to make sure levels are safe for consumers. These limits apply to both food produced domestically and imported from other countries. 'Our UK National Action Plan, published last year, sets out how we will support farmers, growers and other land managers to increase their use of sustainable practices to reduce potential harm from pesticides, while controlling pests and pesticide resistance effectively and protecting food security.
