Pesticides and Valentine’s Day Roses... And When the Facts Speak

I decided to take a biological test carried out after Valentine’s Day to assess the potential presence of pesticide residues in my body.

Each year around Valentine's Day, florists globally prepare to meet a surge in demand for roses. A symbol of love, these flowers also find themselves at the center of one of the most debated topics in our industry: pesticide use. For several years now, I have been keen on understanding the veracities behind the topic, even as I design with the flowers.

So, this year again, just as I did in 2025, I decided to take a biological test carried out after Valentine’s Day to assess the potential presence of pesticide residues in my body. While the idea might sound unusual (a florist taking a toxicology test), I sought to demystify some facts we often overlook.

Why I Chose to Get Tested

Florists handle large volumes of flowers daily, especially during peak seasons like Valentine’s Day or Mother’s Day. Depending on their origin and cultivation practices, these flowers can sometimes carry chemical residues used during their growth, harvest, and transport. Over time, there has been increasing concern about how these residues might affect professionals who handle them every day, from the growers to packers, and florists arranging bouquets, who breathe in the floral air of their shops.

I wanted concrete data, so I entrusted my analysis to the pharmacology-toxicology laboratory at my local university hospital and Eurofins, a leading international player in pesticide bio-monitoring, to conduct the specialized test. The result showed no detectable traces of pesticides or herbicides in my system.

What This Result Means (And What It Doesn’t)

It is essential to be transparent. This result doesn’t mean that the flowers I work with are totally pesticide-free. Numerous studies, as well as some investigations by consumer associations, have shown that cut flowers such as roses, Chrysanthemums, and Gerberas can contain pesticide residues. In fact, researchers sometimes find several dozen different molecules on a single bouquet.

However, and this is where nuance matters, the presence of residues on a flower does not automatically mean exposure or contamination of the florist’s body. Factors such as how we handle the flowers, what protective measures we use, how we ventilate our workspaces, and how careful we are with hygiene all influence whether those residues make contact in any significant way. That is the main message from my little experiment. Data helps us differentiate between perception and assessable reality.

Why Floristry Needs Science and Balance

Discussions about pesticides in floriculture often turn emotional, and understandably so. We are talking about health, the environment, and the products we associate with beauty and love. Yet too often, these conversations rely on generalizations, fear-driven narratives, or incomplete data.

As a professional in this field, I believe our industry deserves better. It deserves better data, better dialogue, and better understanding. Instead of drawing quick conclusions, we need structured research involving scientists, occupational physicians, flower producers, distributors, and florists. The goal should not be to point fingers but to improve collectively.

If we better understand the exposure methodologies and risks, we can focus our efforts where they matter most, and that is to develop safer practices, implement cleaner supply chains, and protect everyone involved in the journey of a flower.

Aligning Passion for Flowers With Respect for Health and the Environment

Conducting a personal pesticide bio-monitoring test is, of course, a small feat. But it is symbolic of a desire to align my passion for flowers with respect for health and the environment. Our profession has always balanced art, science, and human connection. To add environmental responsibility to that list is a duty and an opportunity.

When I received my test results, I felt reassured. This was not because I proved anything definitive, but because I took an evidence-based step within an emotive topic that is often treated abstractly. The facts, in this case, spoke evidently, and they motivate me to keep asking questions, seeking more knowledge, and sharing what I learn.

I know that one individual’s results cannot represent everyone’s experience. We need comprehensive studies, more volunteers, and greater institutional support to monitor pesticide exposure among florists and agricultural workers, because shared knowledge is the first step toward progress.

Let’s Keep the Conversation Going

My goal in sharing this is not to declare victory or to suggest that florists have nothing to worry about. Neither did I share my experience publicly to minimize any risk or start a controversy. I did so to bring facts to a discussion that too often lacks them. As we work with either imported or local flowers, it is crucial to keep evaluating how we can reconcile the three pillars that sustain our profession: human health, environmental protection, and the joy of offering flowers.

To my fellow florists, researchers, and anyone else who cares about this topic, my door is always open for discussion. Let’s exchange ideas, methods, scientific resources, and concrete solutions. If we stay curious and cooperative, we can make the floral industry more beautiful and even more conscious. Flowers are, after all, meant to bring joy and not to spark fear.

FAQ

Why did I test myself for pesticide residues right after Valentine's Day?

Valentine's Day is one of the single most intensive periods of the year for a florist – I handle thousands of flower stems in a very short window. If pesticide residues were going to accumulate in my body, that would be the moment. Running a urine biomonitoring test immediately after gives the most meaningful snapshot of actual exposure. I have now done this for two consecutive years, in 2025 and 2026, to build a consistent personal baseline.

A clean result – does that mean florists have nothing to worry about regarding pesticide exposure?

No, and I want to be direct about this. My personal result does not cancel out the broader concern. Studies consistently show that cut flowers – roses, Chrysanthemums, Gerberas – can carry dozens of distinct pesticide molecules on their stems and petals. What my result illustrates is that the presence of residues on a flower is not the same as those residues entering a professional's body at harmful levels. The gap between surface contamination and biological impregnation depends heavily on individual work practices, protective habits, and daily routines.

What is biomonitoring, and how is it different from testing the flowers themselves?

Surface residue testing detects what is on a flower – it answers the question "are pesticides present?" Biomonitoring goes a step further and measures what is actually inside a person's body. My urine analysis was conducted by the pharmacology-toxicology laboratory of my University Hospital, using a specialized panel run by Eurofins, a leading specialist in human pesticide biomonitoring. It screens directly for pesticide metabolites in the body, which is a far more precise indicator of real-world health exposure than surface sampling alone.

What protective practices might explain a clean result despite heavy flower handling?

I have been deliberate about building protective habits into my daily workflow: wearing gloves when appropriate, maintaining good ventilation in my workspace, and practicing consistent hand hygiene. These are not dramatic measures – they are the kind of quiet, unglamorous professional routines that rarely make headlines. But the evidence from my own body suggests they make a real difference. Exposure is not just about what you touch; it is about how you touch it, for how long, and with what safeguards in place.

What does the floral industry actually need to better understand these risks?

Rigorous, publicly available research – conducted in genuine partnership between occupational physicians, toxicologists, producers, distributors, and frontline florists. Too often, the conversation swings between uncritical reassurance and disproportionate alarm, fuelled by studies whose full results are never shared with the public. What I am advocating for is open, evidence-based dialogue: more biological monitoring of professionals across the sector, more transparency from consumer organizations about full methodology, and a collective commitment to reducing risks without distorting them. Flowers can be both beautiful and safe – but only if we take the data seriously.
