Whelk: what every chef needs to know
Day in, day out, The whelk delivers: a sea snail and falls under the EU-14 allergen for molluscs. Whelks are caught along the North Sea coast and are a traditional Dutch and Belgian street food. They are boiled live in salted water (2–3% salt) for 5–8 minutes, after which the animal is extracted from the shell with a pin or needle. Fresh whelks have a closed operculum (horny lid); an open operculum on a live whelk indicates stress or illness. HACCP: whelks are filter feeders like mussels and oysters; Norovirus contamination from the production area is possible. EU Regulation 853/2004 Annex III Section VII regulates production area classification for live shellfish and molluscs.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
