Alpha-gal syndrome: Meat allergy linked to tick bites rising, CDC says
Up to 450,000 Americans may have a syndrome that can cause dangerous reactions to several types of meat.
The rate of Americans developing a rare meat allergy from tick bites is rising, researchers say, and may have already impacted as many as 450,000 people.
New data released by the Centers for Disease Control and Prevention (CDC) on Thursday shows a steep increase in cases of alpha-gal syndrome.
The allergy triggers a possibly life-threatening reaction to several types of meat or animal products.
US scientists have traced alpha-gal to saliva from the lone star tick.
The tick is identified by the white spot on its back and is mostly found in southern and eastern parts of the US. But experts warn that their range is expanding due to climate change.
Blood-sucking bites from the lone star, formally called the Amblyomma americanum, can make a person sick when they consume certain meat and animal products made from mammals.
The list of dangerous foods for people suffering from alpha-gal syndrome include pork, beef, rabbit, lamb, venison, gelatine, milk, some dairy products and certain pharmaceuticals.
