MINNEAPOLIS, MN — A former Minneapolis florist was forced to close her thriving business last December after connecting debilitating health issues—including chronic fatigue, persistent headaches, and confusion—to daily, long-term exposure to pesticides present on imported cut flowers. Sarah Chen, 30, operated her floral design studio for eight years before her deepening illness made continuing impossible, spotlighting a little-discussed occupational hazard facing florists and highlighting the lack of chemical regulations in the global floral supply chain.
Chen’s difficult decision has galvanized calls for increased awareness and regulatory oversight regarding the chemicals applied to the vast majority of non-domestically grown flowers. Experts caution that while casual consumers face minimal risk, the health burden falls heavily on the florists and workers who handle these chemically treated products for prolonged periods.
Regulatory Vacuum Puts Workers at Risk
Unlike agricultural food products, cut flowers entering the European Union, United Kingdom, and United States are generally exempt from strict maximum residue limits (MRLs) for pesticides. While this is logistically understandable—flowers are not consumed—the regulatory gap creates a substantial risk for industry professionals.
Approximately 85% of flowers sold in countries like the UK are sourced internationally, primarily from major exporting nations such as Ecuador, Colombia, Kenya, and Ethiopia. In these regions, pesticide standards and enforcement often lag, resulting in imported shipments carrying residues of agricultural chemicals that may be restricted or banned in destination markets.
Research has repeatedly demonstrated that these residues can easily be absorbed through the skin or inhaled by florists. A 2018 study analyzing 90 bouquets identified 107 different pesticides. Alarmingly, 70 of these chemicals were later detected in the urine of florists working with the flowers, even among those who wore double layers of protective gloves. Exposure levels to one specific pesticide, clofentezine, exceeded acceptable health thresholds by four times.
Childhood Cancer Case Highlights Plausible Link
The global community has seen preliminary evidence linking parental floristry exposure to severe health outcomes in children. In a landmark case in France, the national Pesticide Victims Compensation Fund officially recognized a connection between a florist’s occupational pesticide exposure during pregnancy and her 11-year-old daughter’s subsequent diagnosis and death from cancer in March 2022.
This tragic outcome prompted further investigation by researchers Jean-Noël Jouzel and Giovanni Prete, who found striking parallels among several floristry families experiencing childhood diseases, including cancer and severe neurodevelopmental disorders. While establishing direct causation is near impossible, researchers note the plausible link merits immediate concern.
“It is surprising that this hasn’t been recognized as a problem before,” said Professor Michael Eddleston, a clinical toxicology expert at the University of Edinburgh, emphasizing the need for dedicated health studies of florists.
Industry Awareness and Education Lag
Many veteran florists report being entirely uninformed about chemical risks throughout their careers. James Mitchell, a long-serving florist in West London, notes that pesticides were never mentioned as an occupational concern.
Chen, who worked without protective gloves for five years of her career, eventually sought medical help after experiencing elevated liver enzyme levels, a potential indicator of poisoning-related liver damage. Her diagnosis prompted her to install air purifiers and seek locally grown, less-treated flowers, but her condition continued to decline until she left the industry entirely. Her subsequent recovery strengthens the hypothesis that her symptoms were linked to her workplace environment.
The general lack of awareness is compounded by a gap in industry professional standards. Currently, no common, publicly accessible occupational hazard guidelines specifically addressing pesticide exposure exist for florists, according to the British Florist Association. Training courses often neglect the topic, leading many industry workers to mistake chemical residue for harmless “dust.”
Moving Toward Safer Practices
The French government has launched a study to quantify flower workers’ pesticide exposure, which is expected to result in regulatory proposals, potentially including maximum pesticide residue limits for imported flowers. Meanwhile, consumer protection groups are pushing for compulsory labeling detailing chemical use.
In the absence of mandated change, individual florists are urged to adopt greater protective measures. Suggestions include:
- Consistent use of protective equipment: Always wearing gloves and masks when handling large batches of imported flowers.
- Improving studio ventilation: Utilizing high-quality air filtration and opening windows.
- Sourcing sustainably: Prioritizing locally grown flowers, often subject to stricter domestic chemical control, or certified sustainable imports.
“Floristry is beautiful, and there’s so many people that have amazing careers,” Chen notes, despite her ordeal. “I don’t want to demonize the industry, but I do think there’s a really dark side to floristry that is just not talked about.” Florists and industry bodies must now prioritize transparency and worker safety to mitigate these invisible, yet substantial, health risks.
