Ticks can cause meat allergy: What you should know
In several places around the world, there is now an increase in the number of people developing an allergy to meat. Researchers point to a surprising cause for this development: tick bites. Although the phenomenon is currently best known in other countries, experts believe it is likely that we will see more cases here in Norway as well.
The allergy occurs after a person is bitten by a specific type of tick. When the tick bites, it transfers a sugar molecule called alpha-gal into the human body. This substance is found naturally in meat from mammals, such as beef, lamb, and pork. When the immune system later detects this substance in the meat one eats, the body reacts with an allergic reaction.
The symptoms of this allergy can be different from those of common food allergies. Many people experience reactions several hours after eating meat, which makes it difficult to link the allergy to the meal itself. Symptoms can range from rashes and itching to more serious reactions such as difficulty breathing.
Although ticks are very widespread in Norway, it is currently uncertain how many Norwegians are affected by this specific allergy. Researchers are now closely monitoring the situation to see if changes in the climate and the prevalence of ticks will lead to more cases in the years to come.
There is currently no cure for this allergy, and the best way to avoid reactions is to avoid meat from mammals. If you suspect that you have developed an allergy after a tick bite, health professionals recommend that you contact a doctor to get a correct diagnosis.
