Alpha-gal allergy has been reported in 17 countries on all six continents where humans are bitten by ticks, particularly the United States and Australia. [11] Alpha-gal allergies are the first known food allergies that present the possibility of delayed anaphylaxis.
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.
Food allergy is principally diagnosed by careful history and examination. When reactions occur immediately after certain food ingestion then diagnosis is straight forward and can be documented by using carefully performed tests such as the skin prick test and the radioallergosorbent test RAST to detect specific IgE antibodies to specific food proteins and aero-allergens.
The test may be performed in people with suspected gluten-related disorders in very specific occasions and under medical supervision, for example in people who had started a gluten-free diet without performing duodenal biopsy. [1] [2] [3] Gluten challenge is discouraged before the age of 5 years and during pubertal growth. [4]

Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
It is excluded when there are normal levels of serum IgE antibodies to gluten proteins and wheat fractions, and no skin reaction to prick tests for wheat allergy. [6] Nevertheless, these tests are not always completely reliable. [11] If an allergic reaction can not be clearly identified, the diagnosis should be confirmed by food provocation ...
