Bisphenol A: still generating debate

Bisphenol A, a chemical compound used in the production of plastics, has been the subject of concern because of its potential negative impact on human health. Recent scientific studies have shown that this compound can affect the endocrine system and cause problems such as obesity, diabetes and cancer. For this reason, several countries have taken measures to limit or prohibit their use in products intended for human consumption. Recently, it was announced that bisphenol A is now banned in baby bottles due to potential risks to infant health. This measure is a major victory for food safety and a step forward in protecting the public from toxic substances such as bisphenol A.

Since March 1, 2011, the European Union (EU) has banned the manufacture of baby bottles containing BPA and since June 1, 2011, the import and marketing of baby bottles containing BPA. So yes, bisphenol A has already been banned for baby bottles in the EU for more than a decade.

This substance is often used in packaging, bottles and cosmetic products, as well as on receipts. For its part, EFSA assesses whether that which comes into contact with food is harmful. Bisphenol is used to prolong the shelf life of foods and prevent them from acquiring a metallic taste. Dietary exposure to bisphenol A (BPA) is a health concern for consumers of all age groups.” This is the conclusion of EFSA’s scientific experts in their new assessment.
Scientists have warned about the risks to the immune system that can be associated with the consumption of this particular substance, even in small amounts. This could trigger a series of autoimmune disorders such as the production of allergies.

BPA is a chemical used in combination with other chemicals in the production of some plastics and resins. It is used, for example, in polycarbonate plastic, a type of clear, rigid plastic used to produce water dispensers, food containers and refillable beverage bottles.
It is also used to produce protective resins found in the inner linings of cans and food and beverage cans. But it is also found in cosmetic containers, metal jar lids and glass bottles. In this case, exposure occurs through the ingestion of food or beverages that are inevitably in contact with that container.

Bisphenol can be absorbed through the skin when it comes into contact with an object containing this chemical. This is possible due to polycarbonate, a material that is resistant and moldable at high temperatures. Due to its wide diffusion it is found in numerous common objects, from toys to water bottles and CDs; even other products such as store receipts, transportation tickets or parking tickets are also impregnated with the compound.

The reason why there is so much discrepancy between the European agencies is one in particular: the dispute over the allowable safe amount of BPA for humans. While the European Medicines Agency includes different methods to study the level of exposure to this chemical, EFSA has proven to be more demanding in reducing it. For their part, both bodies signed a joint document highlighting how they work and perceive the results related to this issue, thus showing their different interpretations and conclusions.
