Kitchen Safety and Cookware Advice: Expert Answers on PFAS, Scratches, and Food Handling

Expert Guidance on Home Kitchen Safety

Recent discussions hosted by the Drexel Food Lab, featuring experts Rachel Sherman and Caroline L. Schauer, have provided clarity on common consumer questions regarding food safety and cookware maintenance. The session addressed concerns ranging from the longevity of non-stick pans to the nuances of preventing cross-contamination in home kitchens.

Non-Stick Cookware and Health Concerns

A primary point of discussion was the status of damaged non-stick pans. Experts advised that if a non-stick surface is scratched, the pan should be disposed of. This is because micro-particles of the coating can separate from the damaged area and potentially mix into food during the cooking process.

Regarding PFAS (per- and polyfluoroalkyl substances) in cookware, the experts emphasized that consumers should look for transparency in manufacturer documentation. When asked about specific "stone-ground" pans, the experts noted that if the manufacturer does not disclose the chemical composition of the coating, it cannot be safely classified as PFAS-free or PTFE-free. Drexel Food Lab testing has identified several non-toxic alternatives, including the Titanium Always Pan Pro and the Caraway Enamel Cast Iron Skillet, as well as budget-friendly options like traditional cast iron from brands such as Lodge and Victoria.

Preventing Common Food Safety Mistakes

Cross-contamination remains a leading cause of home food safety errors. Experts recommended a strict workflow when using a single cutting board: prepare all vegetables first, move them to a clean vessel, and then process raw meat. Additionally, the experts cautioned that kitchen sponges require frequent sanitization, especially after being used to clean surfaces that held raw meat.

On the topic of cooling leftovers, the experts clarified that rice is safe for storage if cooled rapidly. They suggested spreading cooked rice in a thin layer on a tray to bring its temperature below 40°F quickly before transferring it to a storage container, helping to mitigate the risk posed by *Bacillus cereus*.

Practical Implications for Home Cooks

• **Cookware Maintenance:** Inspect vintage and older cookware regularly. While items like seasoned cast iron or certain "copper-clad" stainless steel pans are highly regarded, damaged or rusty items should be retired.

• **Pet Safety:** Stainless steel is generally recommended for pet dishes. While high heat and acidity can cause minor leaching of chromium and nickel, these are considered micronutrients for most pets, provided there is no pre-existing nickel allergy.

• **Verification:** Readers can review the full breakdown of tested non-toxic pans, air fryers, and cutting boards directly through the source publication.
