Hard cooked-and-pressed cheeses - beaufort, comte, emmental, gruyere, parmesan - are explicitly listed as safe even when made from raw milk, because heating and long aging eliminate the Listeria risk; ANSES reaffirmed this cooked-pressed-cheese exception in its February 2026 recommendations for pregnant women and other at-risk groups. Listeriosis during pregnancy can cause miscarriage, premature birth, or severe neonatal infection, and immunity does not develop against it.",
