Clinical Relevance
Sheep’s milk is sometimes recommended as a substitute for cow’s milk in atopic children. However, 15/16 cows´s milk allergic patients had IgE antibodies against sheep’s milk. Crossreactivity with cow’s milk was confirmed in RAST® inhibition. Serum albumin and caseins show homology to the corresponding proteins of cow and sheep. Milking sheep can cause IgE mediated respiratory problems in milk allergic individuals.
Cross-Reactivity
Crossreactivity between sheep's milk and cow's milk and whey might be expected.
Milk from other related animals.
