MINNEAPOLIS, MN— Growing evidence suggests that occupational exposure to high levels of agricultural pesticides residue on imported cut flowers poses a significant, often unrecognized, health risk to florists and industry workers worldwide. This concern comes into sharp focus following the closure of a successful Minneapolis floral studio after its owner, Sarah Chen, 30, attributed years of debilitating chronic illness—including extreme fatigue, headaches, and liver function abnormalities—to continuous chemical contact in her workplace. Chen’s experience, along with critical findings linking florists’ professional exposure to childhood diseases, is prompting urgent calls for increased regulatory oversight and mandatory protective practices.
Chen, who operated her business for eight years, made the difficult decision to close in December 2024 after exhausting efforts to mitigate her worsening symptoms, which a naturopathic doctor suggested stemmed from pesticide poisoning. “To find out that I feel this bad because of my job is horrible and stressful,” Chen explained, highlighting the surprise and secrecy surrounding the issue.
Lack of Regulation Creates Workplace Hazard
While consumers face minimal danger handling an occasional bouquet, experts warn that florists and growers encounter “toxic bombs” daily. Unlike produce, which is subject to maximum residue limits in jurisdictions including the European Union and the United States, cut flowers have no mandatory limits on pesticide concentrations.
This regulatory gap exists despite the majority of flowers sold—roughly 85% in major markets like the UK—being sourced from countries such as Colombia, Ecuador, and Kenya, where pesticide application oversight is often minimal. These chemicals, used to ensure flowers are pest-free and visually flawless, can be easily inhaled or absorbed through the skin by workers in the supply chain.
Dr. Michael Eddleston, a clinical toxicology expert at the University of Edinburgh, noted that the lack of monitoring creates a disincentive for the industry to change legacy practices. “With flowers, nobody’s monitoring, so there’s no incentive to change,” he stated.
Tragic Cases Signal Potential Links
The issue gained tragic international prominence in France when a court recognized a connection between a florist’s occupational pesticide exposure and the death of her 11-year-old daughter, Emmy Dubois, from cancer in 2022. The French Pesticide Victims Compensation Fund ruling was based on the mother’s proximity to chemicals during pregnancy, an official acknowledgment researchers Jean-Noël Jouzel and Giovanni Prete say validates their ongoing investigation into similar childhood cancer and neurodevelopmental disorder cases among florists’ children.
Further research supports the need for concern. A 2018 study analyzed ninety bouquets and detected 107 different pesticides. Alarmingly, detectable amounts of 70 of these compounds were found in the urine of florists participating in the study, even among those wearing two pairs of protective gloves. Exposure to one pesticide, clofentezine—classified as a possible carcinogen by US authorities and banned in the EU for its endocrine-disrupting properties—exceeded acceptable thresholds by fourfold.
Industry Fails to Educate Workers
Many florists remain unaware of the chemical risks. Veteran florist James Mitchell of Kensington Blooms in west London stated that pesticide hazards have never been a subject of discussion within the industry.
The British Florist Association CEO, Angela Oliver, confirmed that there are no publicly available occupational hazard guidelines specifically addressing pesticides for florists, adding that the association does not currently plan to discuss the issue further.
The widespread knowledge gap means essential protective practices, such as wearing gloves and using proper ventilation, are often overlooked or dismissed as unnecessary. Chen recalled instinctively working barehanded for five years before her health crisis prompted deeper investigation. She emphasized that the chalky residue visible on imported stems is not merely dust, but dangerous chemicals.
In response to growing public and media scrutiny, the French government launched a study on flower worker pesticide exposure, which is expected to yield results that could lead to consumer labeling requirements and potential maximum residue limits for cut flowers.
Experts and affected florists urge immediate operational changes. Chen’s advice for florists who love their profession includes prioritizing protective gear, installing air purifiers, and sourcing flowers more frequently from local, transparently grown suppliers.
“Floristry is beautiful, and there’s so many people that have amazing careers,” Chen concluded. “But I do think there’s a really dark side to floristry that is just not talked about.” The mounting evidence suggests that data collection and regulatory intervention are urgently needed to protect the health of an overlooked workforce.
