WHO warns of hidden risks in kitchen utensils

Every day, billions of people around the world use a variety of utensils to prepare their food. However, this everyday act could have a “dark side.” World Health Organization (WHO) has issued a warning about the possible presence of carcinogenic substances in these kitchen instruments.

Experts from the International Agency for Research on Cancer have identified that Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are synthetic compounds that could be harmful to health. These elements They are found in non-stick pans and pots, such as Teflon.

In addition to kitchen utensils, these compounds They can also be found in food packaging, carpets, construction materials, cosmetics, waterproof clothing and fire-fighting foams, among other products.. According to the organization, These chemicals are detected in low concentrations in the blood of most people.and an increase in its levels could disrupt healthy cells, potentially triggering cancer.

Characteristics and uses of chemical compounds

According to the WHO, PFOS and PFOA belong to the group of substances known as perfluoroalkyl and polyfluoroalkyl (PFAS), widely used in various products. Although these substances are appreciated for their stability and surfactant properties in industrial applications, Its resistance to decomposition poses serious risks to human health and the environment.

These compounds are especially valued in the industry for their ability to resist oils, grease, heat, water and stainsmaking them ideal for producing items such as kitchen utensils. In the case of Teflon, PFOA is used as an adhesive agent to fix the non-stick layer.which can be released when it deteriorates.

Impact on human health and the environment

Due to its chemical stability, PFAS do not break down easily, causing them to accumulate in the environment and in organisms for long periods. Several studies have shown that these substances are present in the blood of most people, with higher levels in those who live or work near industrial plants that use them. The main route of exposure is through the ingestion of contaminated water or food, although they can also be inhaled.

For those who live near factories or industrial plants, it is suggested to drink bottled water or use activated carbon filters.

The US Environmental Protection Agency has indicated that in studies with laboratory animals, PFOA and PFOS have shown adverse effects on the reproductive and immune systems, and on organs such as the liver and kidneys. In addition, tumor formation has been observed in these animals. Among the most common effects in humans exposed to these chemicals are elevated cholesterol levels, and they have been linked to low birth weight, alterations in the immune system, cancer (particularly from PFOA) and thyroid hormone dysfunction (in the case of PFOS).

Some studies have suggested that the most exposed people These compounds present a increased risk of developing testicular and kidney canceraccording to the American Cancer Society. They have also been found Possible links to thyroid, prostate, bladder, breast and ovarian cancersalthough further research is required to confirm these associations.

Prevention Measures and Legislation

In 2020, the European Union banned the use of perfluorooctanoic acid (PFOA) and its derivativesbecause These compounds are considered “persistent organic pollutants” (POPs), characterized by their durability in the environment and their ability to disperse widely, even in regions where they do not occur.

PFOA has been included in the list of chemicals regulated by the Stockholm Convention on Persistent Organic Pollutants, which prevents its production in EU countries and those that have signed the agreement, except in specific cases.

Although Completely avoiding contact with PFAS is almost impossible, there are measures to reduce exposure. One of the main recommendations is Replace Teflon cookware with cast iron, stainless steel or ceramic cookwarePFOA-free non-stick cookware is often labeled as such.

One of the main recommendations is to replace Teflon cookware with cast iron, stainless steel or ceramic cookware.

For those who live near factories or industrial plants, it is suggested to consume bottled water or use activated carbon filters.according to the American Cancer Society. Additionally, certain canned foods, such as seafood, may contain higher levels of PFAS and should be consumed with caution.
