A troubling lack of regulation around pesticide residues on imported cut flowers is exposing florists and flower workers to significant occupational health risks, prompting calls for greater awareness and new safety standards across the industry.
The Invisible Threat in the Flower Shop
Florists, often unknowingly, handle flowers daily that are heavily treated with chemicals to ensure flawless appearance and longevity. Unlike food products, cut flowers entering the United States, the United Kingdom, and the European Union are not subject to maximum limits on pesticide residue levels, creating hazardous working conditions for those with regular, intense exposure.
Sarah Chen, a former Minneapolis florist, shut down her thriving eight-year-old business in December 2024 after struggling for years with debilitating symptoms including severe headaches, persistent nausea, and profound fatigue. Chen now attributes her declining health to chronic exposure to chemicals in the cut flower supply. Blood work revealed elevated liver enzymes, pointing to possible poisoning, a diagnosis her naturopathic doctor suggested may be linked to pesticides.
“To find out that I feel this bad because of my job is horrible and stressful,” Chen shared, questioning why this issue remains largely unaddressed by the floristry community.
Evidence Links Florists’ Exposure to Serious Disease
The potential link between occupational pesticide exposure in floristry and adverse health outcomes gained tragic visibility in France. Following a pioneering legal decision, France’s Pesticide Victims Compensation Fund recognized a connection between the 2022 cancer death of 11-year-old Emmy Dubois and the pesticide exposure her mother, a florist, experienced during pregnancy.
This recognition reflects a growing body of research suggesting serious risks. A 2018 study analyzing 90 bouquets identified 107 different pesticides. Alarmingly, 70 of these chemicals later appeared in the urine samples of florists, even those who reported wearing two layers of protective gloves. Exposure levels to the possible carcinogen clofentezine, for example, exceeded acceptable thresholds by fourfold in that research.
While experts caution that establishing direct, individual causation for long-term illness remains challenging, researchers Jean-Noël Jouzel and Giovanni Prete are investigating multiple French florists whose children have experienced severe health crises, including neurodevelopmental disorders and cancer, which are plausibly linked to parental pesticide handling.
Clinical toxicologist Professor Michael Eddleston of the University of Edinburgh notes that the lack of monitoring in the flower trade removes any incentive for global growers to reduce chemical reliance. “It surprises me that this hasn’t been picked up before and it hasn’t been recognized as a problem. But I think it’s something to worry about,” he stated.
An Industry Education Gap
The majority of cut flowers sold in the UK and US originate from countries with minimal environmental and labor oversight, such as Colombia, Ecuador, and Kenya. The opaque supply chain means that independent florists often purchase “blind” from wholesalers without information on chemical treatment or origin.
Many florists report being entirely unaware of the chemical hazards. James Mitchell, a London florist with two decades of experience, admits the topic has “never even come up” in his career. Compounding the issue, the British Florist Association CEO, Angela Oliver, stated that no publicly available occupational hazard guidelines specifically address pesticide risks for florists, often leaving awareness to anecdotal evidence.
Rachel Webb, a Gloucestershire florist, only learned of the risks after reading about the Dubois tragedy. “I’ve definitely been ingesting whatever pesticides were on these flowers,” she lamented, noting simple but dangerous practices she has observed, like florists cutting food with the same scissors used on chemical-laden stems.
Path to Safer Practices
Though regulatory progress is slow—the French government, facing pressure, has launched a multi-year study that may eventually lead to establishing maximum residue limits in flowers—florists can take immediate steps to mitigate personal risks.
Recommended Safety Measures for Florists:
- Consistent Use of Personal Protective Equipment (PPE): Always wear gloves when handling imported flowers and stems.
- Improve Ventilation: Use air purifiers and ensure studios and workspaces are well-ventilated, opening windows whenever possible.
- Source Locally: Prioritize purchasing flowers from local, sustainable, or certified organic growers who follow stringent environmental standards and chemical restrictions.
- Hygiene Protocols: Wash hands thoroughly and immediately after handling flowers and before eating or drinking.
Former florist Sarah Chen, who found her symptoms vanished entirely after leaving the industry, emphasizes that awareness is not meant to demonize the craft, but to ensure longevity. “Floristry is beautiful,” she says. “But there is a really dark side to floristry that is just not talked about.”
