Now to a strange and really startling new warning about tick bite. Some are suffering violent reactions after eating burgers or steaks and some ending up in the er. Let's turn to Dr. Jennifer Ashton. Good morning to you. Good morning. This sounds so -- sorry this is not a medical term -- weird but what's the medical explanation. We don't know. Is this really a culinary nightmare or a medical mystery. What happens is you'll get bitten by the tick. The tick then incites an immune reaction to a sugar molecule contained in meat. Right? There's sugar in meat then when you eat meat down the road, pork, lamb or beef, not poultry or chicken, luckily, your body sees that sugar molecule, triggers a massive allergic response and in some cases it can be very, very serious. So this is a shortcut to ruining every barbecue this summer. Pretty much. Does it last forever. In some cases it can be permanent. They're not taking any chances those who suffered it. S that different from the dear tick associated with Lyme disease. This is the lone star tick. Much larger than a deer tick. Originally it was only located in the south but if you look at a map, it's now pretty much half the country. South all the way up to Maine so, again, get those pets treated and remember to protect yourself against ticks. Okay, so if you start developing symptoms, first of all what are the Simms you should look for and what do you do. Three to six hours after eating meat, hives, swelling, you want to seek medical attention and speak to an I wi allergist and get a diagnosis. That is a clinical term, weird, apparently. We appreciate it. Absolutely. Paula, back over to you. Devastating for all the carnivores, as well.
