Pig allergy testing. Scientists performing a skin prick allergy test on an anaesthetised pig (Sus scrofa domesticus). 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. | |
