[Delayed anaphylaxis after ingestion of meat. Carbohydrate epitope galactose-α-1,3-galactose as cause of severe anaphylactic reactions].

: The correlation between anaphylaxis after consumption of meat and the carbohydrate epitope galactose-α-1,3-galactose (α-Gal) was first described in oncologic patients treated with cetuximab. An association with tick bites and parasitosis is suspected. We report on a healthy patient who developed sudden anaphylactic reactions after the ingestion of meat. Serologic and skin tests confirmed sensitization to α-Gal. Avoiding the consumption of mammalian meat led to a complete absence of symptoms.
