PFAS In Commercial Salad Bar Deli Container Coatings At Grocery Stores

Water Contamination Lawsuit News

Grease-resistant coatings on deli containers and salad bar packaging may release PFAS into rinse water during routine grocery store cleaning

Thursday, March 12, 2026 - Modern grocery stores rely heavily on prepared food sections that include salad bars, hot food stations, and deli counters. These areas use large volumes of disposable containers designed to hold oily, moist, or hot foods without leaking or soaking through. Many of these containers are coated with grease-resistant treatments that allow them to perform well even when filled with soups, pasta dishes, or prepared salads. Environmental researchers have begun examining whether some of these coatings contain fluorinated compounds that can release PFAS during use and disposal. PFAS water contamination lawyers say grocery stores represent an overlooked pathway for contamination because food service departments generate continuous waste streams and cleaning cycles throughout the day. Leading water cancer attorneys note that containers coated to resist grease may shed small amounts of chemical residue when they are rinsed, stacked, or disposed of, allowing those residues to enter store drainage systems.

According to the U.S. Environmental Protection Agency, PFAS chemicals have historically been used in food packaging because they help materials resist oil, moisture, and heat. The EPA has also reported that these compounds are extremely persistent in the environment and can remain in water systems for long periods once released. In grocery stores, deli workers frequently rinse containers that have been returned by customers or used for food preparation before disposing of them. In addition, salad bar trays, utensils, and surrounding surfaces are washed repeatedly during daily sanitation routines. When grease-resistant packaging breaks down or comes into contact with hot foods and cleaning solutions, traces of PFAS coatings may transfer into rinse water. That water typically flows into floor drains connected to municipal sewer systems, where treatment facilities may not be able to remove these persistent compounds.

The volume of prepared food sold at modern supermarkets means this process can occur continuously throughout the day. Large grocery stores may distribute thousands of deli containers daily, particularly in locations with busy hot-food counters or ready-to-eat meal stations. While each individual container may release only a tiny amount of residue, the cumulative effect across hundreds of stores and millions of packages could create a measurable source of PFAS entering wastewater systems. Environmental monitoring studies have increasingly focused on food packaging as a potential contributor to chemical contamination because coatings designed to resist grease and moisture often rely on similar fluorinated chemistry used in other stain-resistant materials.

Growing awareness of PFAS contamination has prompted some grocery chains and packaging manufacturers to explore alternatives. New packaging materials made without fluorinated compounds are beginning to appear, including plant-fiber containers treated with alternative grease barriers. Some retailers are also reviewing procurement policies and asking suppliers to certify that deli packaging is free of PFAS-based coatings. In summary, grease-resistant deli containers used at grocery store salad bars and hot-food stations may represent a quiet but continuous pathway for PFAS to enter wastewater systems. Identifying safer packaging materials and improving transparency in food packaging ingredients could help reduce this overlooked source of contamination while allowing grocery stores to maintain food safety and convenience for customers.
