Goat's and Sheep's Cheese
Several allergic reactions after ingestion of feta (cheese made from sheep's milk) in a 15-year-old boy, after ingestion of sheep's or goat's cheese in a 25-year old patient, both tolerated ingestion of diary procucts from cow's milk (1) Allergic reactions after eating goat's cheese and after touching of goat's and sheep's cheese in a 2-year-old girl with tolerance to dairy products from cow's milk (2) A young adult male had severe a anaphylactoid reaction after eating goat's cheese; goat's and sheep's milk elicited mainly oral pruritus while cow's milk and cheese was well tolerated (3) |
