Pig allergy testing. Close-up of the skin of a pig (Sus scrofa domesticus) after a skin prick allergy test. Solutions containing different food allergens are placed in drops on the skin. Each location is labelled and the skin is then pricked with a needle to allow the allergen to enter the body. Red areas on the skin indicate allergic reactions to the corresponding food substances. | |
