A recent study by the Environmental Working Group (EWG) reveals that chlormequat chloride, a pesticide found in popular cereals like Cheerios and Quaker Oats, may be linked to fertility problems. The study indicates that a significant portion of Americans are exposed to this “highly toxic agricultural chemical,” raising concerns about its potential impact on human health.
Key Concepts:
- Chlormequat Exposure: Approximately 80% of Americans have been exposed to chlormequat chloride, a pesticide associated with fertility and growth issues in animals.
- Human Impact: While some studies found no adverse effects on fertility, the EWG suggests potential harm to humans based on observed issues in animals.
- Rat Study Findings: Exposure to chlormequat in rats led to reduced sperm motility, lower male testosterone levels, delayed puberty onset, and decreased weights of male reproductive organs.
- Consumer Exposure: Urine samples from 2017 to 2023 show an increasing number of participants with chlormequat concentrations, indicating rising consumer exposure.
- Oat-Based Foods: Testing 13 oat-based foods, including Cheerios and Quaker Oats, the EWG detected higher-than-safe levels in 11 items.
- Regulatory Context: Chlormequat, approved only for ornamental plants, is allowed on imported oats since 2018, contributing to consumer exposure.
- Recommendations: The EWG recommends choosing organic oat products to reduce exposure to synthetic pesticides like chlormequat.
What is Chlormequat?
- Chemical Nature: Chlormequat chloride is a plant growth regulator and a quaternary ammonium salt. It is commonly used in agriculture to control the growth of plants, promoting shorter and sturdier stalks.
- Purpose: The primary purpose of chlormequat is to reduce lodging, which is the bending or breaking of plant stems. This is particularly important in cereal crops, where shorter, stronger stems can prevent yield losses due to adverse weather conditions.
- Regulatory Approval: Chlormequat is approved for use in the United States only on ornamental plants, such as flowers and decorative plants. Its use on food crops is restricted in many regions due to concerns about residues in edible parts.
- Consumer Exposure: Despite its limited approval for use on specific plants, chlormequat has been detected in certain food products, particularly cereals. The Environmental Working Group (EWG) study suggests that Americans are exposed to chlormequat through the consumption of oat-based foods.
- Health Concerns: The recent study raises concerns about the potential health impact of chlormequat exposure. While its use is intended to affect plant growth, the study indicates possible adverse effects on fertility and reproductive health in animals, prompting questions about its safety for human consumption.
