Paris, France – June 9, 2025 – A growing chorus of medical professionals is voicing concern over the presence of cadmium, a toxic heavy metal, in common food items. This omnipresent environmental contaminant poses notable health risks, prompting calls for immediate public action.

Cadmium: An Invisible Threat in Yoru Food?

Cadmium, identified by the atomic number 48, is a malleable, bluish-white metal widely used in industrial applications. its presence in the food chain has become a focal point of discussion, particularly after the recent National Conference of Liberal Doctors Urps in France on April 24, 2025.

The organization Safe Food Advocacy europe has echoed concerns initially raised by Public Health France, which has issued multiple alerts since 2019. The National Agency for Food, Environmental and Labor Safety and Work (ANSES) has also urged the reduction of cadmium levels in food to the lowest possible point, highlighting the issue since at least 2011.

The Root of the Problem: Phosphate Fertilizers

The primary culprit is the widespread use of phosphate fertilizers in agriculture. These fertilizers often contain cadmium, which accumulates in the soil and is afterward absorbed by plants through their roots. As an inevitable result, cadmium finds its way into a variety of foods, including green leafy vegetables, breakfast cereals, pasta, bread, potatoes, and other common vegetables.

Did you Know: Studies suggest that the bioavailability of cadmium may be higher in animal-based foods compared to plant-based foods? However, research also indicates that certain plants, like kale, can inhibit cadmium absorption.

Health Risks Associated with cadmium Exposure

Exposure to cadmium poses serious health risks, primarily affecting the kidneys. Irreversible renal damage can occur, increasing the likelihood of kidney stone formation. furthermore, prolonged exposure elevates the risk of certain cancers, notably prostate and lung cancer, and also bone fragility.

The primary route of exposure is through oral consumption (food), with inhalation playing a less significant role.

A “Public Health scourge” Demands Action

In a recent press release, medical professionals have declared the situation a “perfectly documented sanitary emergency,” emphasizing the urgent need for public action and political decisions to protect citizens. whether this will lead to a ban on cadmium in agriculture remains to be seen, but the gravity of the situation is clear.

What steps can individuals take to mitigate their exposure to cadmium? Should governments implement stricter regulations on fertilizer composition?

Cadmium: A Hidden Public Health Scourge

Cadmium: A Hidden Public Health Scourge

Cadmium, a naturally occurring heavy metal, poses a notable threat to public health. Its widespread presence in the environment, coupled with its toxicity, demands careful attention. Understanding the cadmium toxicity, its cadmium exposure routes, and the associated cadmium health risks is crucial for protective measures. This article delves into the details of cadmium poisoning, its sources, effects, and the crucial steps you can take to protect your health.

What is Cadmium? Unveiling a Risky Element

Cadmium (Cd) is a soft, silvery-white metal found in the EarthS crust. It’s frequently mined as a byproduct of zinc, lead, and copper extraction. While used in various industrial applications, its inherent toxicity makes it a significant environmental and public health concern. Key cadmium facts include its persistence in the environment and potential for long-term bioaccumulation.

Cadmium’s Common Uses

Despite its toxicity, cadmium finds use in several industrial applications. Understanding these uses helps identify potential cadmium sources. Some of the most prevalent usages include:

• Batteries: Nickel-cadmium (Ni-Cd) batteries are a major source of cadmium.
• Pigments: Cadmium compounds are used to create luminous yellow, orange, and red pigments in paints, plastics, and ceramics.
• Electroplating: Cadmium is used to coat other metals to protect them from corrosion.
• Stabilizers in plastics

Sources of Cadmium Exposure: Where Does Cadmium Come From?

Exposure to cadmium can occur through various pathways.Identifying these cadmium entry points is essential. The most common sources include:

Environmental contamination

Cadmium in the environment arises from both natural processes and human activities. Volcanic eruptions and forest fires can release cadmium. However, industrial activities and agricultural practices are significant contributors to environmental contamination.

• Mining and Smelting: These processes release significant amounts of cadmium into the air, water, and soil.
• Fertilizers: Phosphate fertilizers frequently enough contain cadmium, leading to soil contamination.
• Waste Disposal: Improper disposal of cadmium-containing products, such as batteries, can result in environmental pollution.

Dietary Intake

Food is a primary route of cadmium ingestion. Plants can absorb cadmium from contaminated soil, and animals can accumulate it from their feed. Certain foods are known to have higher cadmium levels,including:

• Leafy vegetables: Spinach and lettuce can accumulate cadmium from the soil.
• Shellfish: Cadmium bioaccumulates in marine organisms, especially shellfish.
• Grains: Increased cadmium in soils can result in higher uptake in grains.
• Offal (liver and kidneys): These organs may accumulate cadmium in higher concentrations from exposed animals.

Inhalation

Breathing in cadmium-containing particles is another path of exposure.This is particularly relevant for people working in industries where cadmium is used or produced. Learn more about the dangers of workplace air pollution.

Cadmium Poisoning Symptoms and Health Effects

Cadmium poisoning can manifest in a variety of ways. The effects depend on the level and duration of exposure. Chronic exposure is particularly concerning and can cause serious health problems. The effects can vary greatly depending on the level of cadmium exposure and the individual affected.

Acute Exposure Symptoms

Acute exposure is a high dose over a short time.

• Respiratory issues: Metal fume fever, lung irritation, and potential pulmonary edema.
• Gastrointestinal problems: Nausea, vomiting, and abdominal pain.

Chronic Exposure Effects: Long-Term Health Risks

Prolonged exposure to lower levels of cadmium can result in severe and potentially irreversible health issues.

Organ System Affected	Health Effect / Symptom
Kidneys	Kidney damage, including proteinuria (excess protein in urine) and kidney failure.
Bones	Bone weakening, including osteomalacia and osteoporosis. Increased risk of fractures.
Lungs	Chronic obstructive pulmonary disease (COPD) and lung cancer.
Prostate	Increased risk of prostate cancer.
Cardiovascular System	Hypertension and increased cardiovascular disease risk.

Protecting Yourself: mitigation and Prevention

Preventing cadmium exposure is paramount. Several strategies can help minimize your risk and ensure your well-being. Implement these cadmium mitigation techniques to stay safe.
