The Design Flaw in California's Proposition 65 Warning Labels

Burkey Belser (1947–2023), the graphic designer of the Nutrition Facts Panel, created one of the 20th century's most important designs. But a recent purchase of gluten-free flatbreads at Whole Foods reveals a critical flaw in warning label design. The product, Absolutely! flatbreads, carried a California Proposition 65 warning about acrylamide, a chemical formed during high-temperature cooking that may cause cancer. The warning was inconspicuously placed on the side panel, leading to consumer confusion. The author discovered the warning only after eating the product. Whole Foods staff were unaware of the warning and refunded the purchase. Proposition 65 requires businesses to warn about significant exposure to listed chemicals, including acrylamide, but a recent court ruling exempts businesses from warning about acrylamide in food. The incident underscores the tension between legal compliance and effective design: a poorly designed warning can increase fear rather than inform. The Nutrition Facts Panel, adopted in 1992, was developed with graphic experts to ensure legibility, but subsequent warning labels lack similar design rigor.
