13 Nov 2019 --- Cooking with plastic utensils such as spatulas, whisks and kitchen spoons could pose health risks to liver and thyroids, according to a study conducted by the German Federal Institute For Risk Assessment (BfR). The toxic components are oligomers, composed of simple plastic building blocks and are unintentionally created in plastic production. The BfR recommends keeping the contact time with hot foods (above 70 °C) short when using polyamide (PA) kitchen utensils, but does not advise to refrain from their use in general.
