“…Our case is also unique as it presented in a young child. In previous cases, the age ranged from 2 to 27 years old,4–8 12 and it was stated that goat’s and sheep’s milk allergy differs from cow’s milk allergy in that it generally affects older children and appears later in life 2…”

“…The majority of reported cases are from Europe (Spain,4 6 Italy,7 France2 and Portugal5). This can possibly be due to a Mediterranean diet, in which goats and sheep are the main source of animal fat, and are commonly used as sources of cheese and yoghurt 13.…”

“…While cow’s milk allergy can be IgE-mediated or non-IgE-mediated, reported cases of goat’s and sheep’s milk allergy with tolerance to cow’s milk have so far been described only as IgE-mediated allergic reactions 2 4–8. IgE-mediated reactions occur within 2 hours after ingestion of a particular allergen 9.…”

Immune-mediated reactions to dairy products may vary depending on the mammalian source. We present a case of anaphylaxis to goat/sheep's milk with tolerance to cow’s milk. A 4-year-old boy of Eastern European descent presented with gastrointestinal and respiratory symptoms within minutes after eating a goat/sheep’s milk-derived food product. The tryptase level measured 1 hour post initial symptoms and 1 month after the allergic reaction were 14.6 µg/L and 5.1 µg/L, respectively (norm: 0.0–13.5 µg/L), confirming the diagnosis of anaphylaxis. A skin prick test performed 1 month after the reaction was highly positive for goat/sheep’s milk, but negative for cow’s milk. Skin prick tests may establish a life-threatening goat/sheep’s milk allergy. Goat/sheep’s milk allergy should always be considered in cow’s milk-tolerant patients who present with an allergic reaction to dairy products, or when undergoing/have completed of oral immunotherapy for cow’s milk allergy.
