“Nothing Says Love Like Chemicals”: Valentine’s Roses Often Covered in Pesticides, Testing Finds

Valentine’s Day roses may look romantic, but new testing shows many bouquets come with an unwelcome extra: high levels of pesticide residue. Consumer advocates say the findings highlight a largely hidden problem in the global flower industry, where heavy chemical use is common and regulation remains uneven.
A recent investigation by the Environmental Working Group analyzed roses purchased from major retailers in several U.S. cities ahead of Valentine’s Day. Laboratory tests detected traces of more than a dozen different pesticides on some flowers, including chemicals restricted or banned for use on food crops. While roses are not eaten, researchers warn that frequent handling — by florists, warehouse workers, and consumers — can still pose health risks.
“People associate roses with love and celebration, but what we found was a cocktail of chemicals,” said an EWG spokesperson. “These pesticides don’t disappear when the flowers are cut. They remain on petals and leaves that people touch and bring into their homes.”
Most roses sold in the United States are imported, primarily from Colombia and Ecuador, where large-scale flower farms rely on intensive pesticide spraying to meet demand for flawless blooms. Industry experts say pests and fungal diseases thrive in the humid greenhouse conditions used to grow roses year-round, making chemical control the cheapest and fastest solution.
Testing found residues of fungicides and insecticides commonly used in commercial flower production. Some of these substances have been linked in scientific studies to hormone disruption, respiratory problems, and skin irritation. Although the amounts detected were within legal limits for ornamental plants, advocates argue that safety standards for flowers are far weaker than those for fruits and vegetables.
The U.S. Department of Agriculture does not regulate pesticide residues on cut flowers in the same way it monitors food products, because roses are not intended for consumption. This regulatory gap means consumers rarely receive information about what chemicals were used to grow the flowers they buy.
Florists are among the most exposed. Many handle thousands of stems daily in the days leading up to Valentine’s Day. “We’ve had workers complain about headaches and rashes during peak seasons,” said a shop owner in New York who asked not to be named. “We wear gloves now, but customers don’t think about that when they’re holding a bouquet.”
Environmental groups also point to the impact on farmworkers in exporting countries. Reports from labor organizations describe frequent pesticide exposure, limited protective equipment, and long working hours during the Valentine’s rush. “The health burden is not shared equally,” said a labor rights advocate based in Bogotá. “Those growing the flowers face the highest risks.”
The flower industry disputes that roses pose a danger to consumers. Trade associations maintain that approved pesticides are used according to safety guidelines and that exposure levels are minimal. “These products are essential to protect crops and ensure quality,” said a representative of a major floral exporter. “Without them, we could not meet global demand or control disease outbreaks.”
Still, demand for alternatives is growing. Organic and “pesticide-free” roses are becoming more available, though they are often more expensive and harder to source in winter. Some florists are shifting to locally grown flowers or encouraging customers to buy potted plants instead of cut roses.
Health experts recommend simple precautions: washing hands after handling flowers, keeping bouquets away from food preparation areas, and avoiding sleeping with flowers near pillows or beds. Removing outer petals and using gloves when arranging bouquets can also reduce exposure.
For consumers, the findings challenge the image of roses as a harmless symbol of romance. “It’s ironic that a gift meant to express care may come with chemical risks,” said the EWG spokesperson. “We’re not saying people should stop buying flowers. We’re saying they deserve transparency and safer choices.”
As Valentine’s Day sales continue to soar each year, advocates hope the spotlight on pesticides will push regulators and retailers toward stricter standards. Until then, the classic bouquet may carry a hidden message alongside its petals: love, wrapped in chemicals.
