You can eat black pudding raw only if it is the commercially produced, pre- cooked variety, which is common in the UK and similar markets. Most black pudding sold is already cooked during manufacturing and is technically safe to eat cold or without further cooking. However, cooking black pudding (such as frying, grilling, or baking) is generally recommended for better flavor and texture. If you purchase black pudding fresh from a butcher or raw meat counter and it is not pre-cooked, it must be cooked thoroughly before eating to avoid any food safety risks. Also, if you are pregnant or immunocompromised, it's safer to eat only cooked black pudding. In summary:

• Pre-cooked commercial black pudding: safe to eat cold or raw.
• Raw or butcher’s black pudding: must be cooked before eating.
• Cooking enhances the taste and texture significantly.

Always check packaging labels and follow storage instructions to ensure safety.
