When you peel back the lid of a can of soup, you are at the end of a complex process that brings this meal to the table. Consider the path it has traveled: from ingredients being harvested, through the stages of cooking, canning, and finally landing in the grocery aisle. Yet, with each phase, there’s a possibility for an unintended addition, an inadvertent hitchhiker that ideally shouldn’t make its way into the bowl.

While concerns about PFAS and BPA have been longstanding, other plasticizers have not received as much attention. For more than 25 years, Consumer Reports has been probing the presence of bisphenols and phthalates in food and its packaging.

In the most recent series of tests by Consumer Reports, the examination of the chemicals has been broadened to include a more extensive range of food items, aiming to measure the prevalence of these substances in the typical American diet. The findings are concerning; bisphenols and phthalates are widely found in the food supply, despite increasing evidence of their potential health risks.

The Uninvited Guests in Food

The study’s results regarding phthalates are particularly alarming, as these substances were identified in almost all tested food products, frequently in high concentrations. Neither the type of packaging nor the food category seemed to markedly affect the prevalence of these detrimental chemicals. Notably, even organic foods, often deemed safer by consumers, were not spared from significant phthalate contamination.

The levels of phthalates in food products exhibited considerable variation, according to the report. Products within the same brand could have significantly different levels, indicating that contamination is not an unavoidable consequence. According to James Rogers, who oversees product safety testing at Consumer Reports, this suggests that there are ways to reduce the presence of these chemicals in food.

The Elusive Entry Points

The challenge lies in understanding how these chemicals enter food.

Initial efforts focused on limiting exposure through packaging, but recent findings indicate that phthalates, in particular, can infiltrate the food through various routes. Plastic used in tubing, conveyor belts, gloves during food processing, and even contaminated water and soil can introduce these harmful chemicals into meals.

Unfortunately, there are limited regulations governing their use in food production, and manufacturers are not required to test foods for their presence.

The Health Risks

The detection of bisphenols and phthalates in the food supply has ignited significant unease within the business community, particularly due to their classification as endocrine disruptors.

These chemicals pose a formidable risk as they can disrupt hormone production and regulation, potentially precipitating a spectrum of health complications. These include, but are not limited to, birth defects, premature births, and an array of neurodevelopmental disorders.

Furthermore, their impact extends to more insidious health conditions like infertility, diabetes, obesity, cardiovascular diseases, and certain forms of cancer. A critical aspect of these health issues is their gradual development over time, complicating the task of tracing specific causal relationships. This slow progression underscores the necessity for businesses, especially those in the food and chemical sectors, to prioritize understanding and mitigating the long-term impacts of these substances on human health.

The pervasive nature of plastics in our daily lives ensures that exposure to these chemicals is nearly constant. While the human body can eliminate bisphenols and phthalates relatively efficiently, the constant influx of these chemicals means they enter the bloodstream and tissues as quickly as they are removed. This ongoing exposure, along with the potential for cumulative harm, further complicates the assessment of health risks associated with these chemicals.

The Need for Regulation

The findings by Consumer Reports underscore the urgent need for regulatory action.

While authorities in the United States have restricted certain phthalates in children’s toys, there are currently no substantial limits on the presence of these chemicals in food packaging or production. The Food and Drug Administration recently requested additional data on the use of plasticizers in materials that come into contact with food during production, potentially leading to updated safety assessments. However, such actions remain overdue and essential in safeguarding the food supply.

Consumer Reports believes that supermarket chains, fast-food establishments, and food manufacturers should play a crucial role in addressing this issue. They must set specific goals to reduce and eliminate bisphenols and phthalates from all food packaging and processing equipment throughout their supply chains. Some companies that were identified as having products with high phthalate levels did not respond to requests for comment by the publication, highlighting the need for industry accountability.

The Quest for Safer Alternatives

In the dynamic landscape of the chemical industry, firms are increasingly called upon to pivot towards research and development, a venture essential for crafting safer and more sustainable materials.

This sentiment is echoed by Hanno Erythropel, from Yale University’s Center for Green Chemistry and Green Engineering, who advocates for the creation of materials that are not only functional but also non-toxic, biodegradable, and renewable. These advancements, particularly in developing alternatives to traditional plastics, represent a formidable yet commendable challenge, one that is integral to safeguarding the food supply.

In summary, the issue of plastic chemicals in food is a pressing concern that requires immediate action from regulatory bodies, manufacturers, and consumers. While awaiting updates in regulations, consumers can actively reduce their exposure to these chemicals, and companies should prioritize food safety in their supply chains. Collaboratively, there’s an opportunity to strive for a future where food is devoid of these harmful additives.
