What it is
Pork casings are the cleaned intestines of pigs, typically the small intestine, used as a natural casing for sausages. After harvesting, the casings are cleaned, processed, and preserved, often with salt, to prepare them for use in meat production.
Why it's used
Pork casings are used to hold ground meat mixtures together in sausages, hot dogs, and bratwurst. They provide the characteristic shape and 'snap' when bitten into, and are edible.
Health notes
Pork casings are considered a food ingredient and are generally recognized as safe (GRAS) by the FDA. They are a source of protein and fat. Regulatory bodies like JECFA and EFSA have evaluated similar food ingredients. No specific health concerns are associated with typical consumption of pork casings.
Allergen info
Not a major allergen. Pork casings are derived from pork, which is not one of the nine FDA major allergens.
