After years of handling cut flowers treated with pesticides, a florist's child succumbs to leukemia.

The article discusses the tragic case of a woman in France whose child’s leukemia was linked to her exposure to pesticides while working with cut flowers. Despite the joy flowers can bring, their often contaminated nature raises serious health concerns. A report revealed that the child was affected by chemicals from the flowers, leading to a diagnosis of acute lymphoblastic leukemia and eventual death. The article highlights the lack of regulations on pesticide levels in cut flowers and ongoing debates about the health risks for those handling them.

While cut flowers bring happiness to many, a recent case from France highlights a troubling aspect of their production. A woman has received compensation after her child tragically lost their life to leukemia, which was linked to exposure to cut flowers.

This heartbreaking story emerged from an investigation by Radio France and “Le Monde.” The woman worked for a flower importer, regularly unpacking deliveries, even during her second pregnancy. Post-birth, the midwife raised concerns about the baby’s weight and noted an unusually dark placenta. At just three years old, the child was diagnosed with acute lymphoblastic leukemia (ALL) and passed away seven years later despite undergoing chemotherapy.

Afterward, the mother discovered that the flowers she handled daily were laced with numerous pesticides. She took her case to the Compensation Fund for Pesticide Victims, where experts unanimously agreed on the connection between her job and her child’s illness.

A Challenging Link Between Pesticides and Leukemia

The relationship between pesticides and leukemia is complex and difficult to establish. Leukemias arise when precursor cells of white blood cells proliferate uncontrollably, displacing healthy blood components. The condition can be categorized into myeloid leukemia (originating in the spinal cord) and lymphatic leukemia (originating in the lymphatic system).

Acute lymphoblastic leukemia can affect individuals at any age, though it is particularly common in children under five, with approximately five cases per 100,000 children. Fortunately, 90 percent of those diagnosed can be cured through chemotherapy, despite potential late-onset effects.

Research indicates that the genetic material of cells can be altered during pregnancy, but the reasons behind this transformation remain largely unclear. Pesticide exposure during pregnancy is a potential risk factor, with epidemiologists noting the dangers associated with this exposure.

Aurélie Berthet, head of Environmental Medicine at the University of Lausanne, stated, “Epidemiological studies suggest a notable correlation between a mother’s occupational exposure during pregnancy and/or the first year of life and the emergence of ALL in their children.” However, establishing a direct causal relationship between pesticide exposure and cancer remains challenging.

Ben Spycher, an expert in environmental factors and childhood cancers at the University of Bern, echoed these sentiments, emphasizing the complexity of linking environmental factors to childhood cancers.

No Legal Limits for Pesticides on Cut Flowers

Despite the general consensus on pesticide contamination in cut flowers, there are currently no legal limits on pesticide residues like those found in fruits and vegetables, neither in the European Union nor in Switzerland.

The majority of cut flowers are imported from non-European nations, where pesticides—including insecticides and fungicides banned in Europe—are still in use. An analysis by the Austrian environmental group Global 2000 revealed pesticide residues in 97 percent of flower samples in Austria and Germany, with 72 percent deemed harmful to human health.

Hygiene Measures to Protect Florists

It raises the question of how much exposure florists endure through skin contact or inhalation while handling flowers. “For florists, the dose is likely low,” Berthet noted, “but their repeated exposure over five to six days a week means they are chronically receiving low doses of pesticides.”

A Belgian study noted elevated pesticide metabolite levels in the urine of florists, though the German Federal Institute for Risk Assessment (BfR) critiqued the study’s methodology. While not disputing that contamination exists, the BfR emphasized that risks can be mitigated through proper hygiene practices like wearing gloves and separating work from food.

The Swiss Florists’ Association has been proactive, having released guidance on skin protection and pesticide handling in collaboration with Zurich University of Applied Sciences. Members are continually educated about the potential risks associated with cut flowers, particularly in light of the recent case in France.

For individuals placing a bouquet in their home, there’s minimal risk. However, those involved in cultivating and arranging these flowers face more significant challenges.
