One Bite From This Tick Can Make You Allergic to Meat

We like to believe that there’s no such thing as a bad organism, that every creature must have its place in the world. But ticks are really making that difficult. As if Lyme disease wasn't bad enough, scientists say some ticks carry a pathogen that causes a sudden and dangerous allergy to meat. Yes, meat.

The Lone Star tick (Amblyomma americanum) mostly looks like your average tick, with a tiny head and a big fat behind, except the adult female has a Texas-shaped spot on its back—thus the name.

Unlike other American ticks, the Lone Star feeds on humans at every stage of its life cycle. Even the larvae want our blood. You can’t get Lyme disease from the Lone Star tick, but you can get something even more mysterious: the inability to safely consume a bacon cheeseburger.

"The weird thing about [this reaction] is it can occur within three to 10 or 12 hours, so patients have no idea what prompted their allergic reactions," allergist Ronald Saff, of the Florida State University College of Medicine, told Business Insider.

What prompted them was STARI, or southern tick-associated rash illness. People with STARI may develop a circular rash like the one commonly seen in Lyme disease. They may feel achy, fatigued, and fevered. And their next meal could make them very, very sick.

Saff now sees at least one patient per week with STARI and a sensitivity to galactose-alpha-1, 3-galactose—more commonly known as alpha-gal—a sugar molecule found in mammal tissue like pork, beef, and lamb. Several hours after eating, patients’ immune systems overreact to alpha-gal, with symptoms ranging from an itchy rash to throat swelling.

Even worse, the more times a person is bitten, the more likely it becomes that they will develop this dangerous allergy.

The tick’s range currently covers the southern, eastern, and south-central U.S., but even that is changing. "We expect with warming temperatures, the tick is going to slowly make its way northward and westward and cause more problems than they're already causing," Saff said. We've already seen that occur with the deer ticks that cause Lyme disease, and 2017 is projected to be an especially bad year.

There’s so much we don’t understand about alpha-gal sensitivity. Scientists don’t know why it happens, how to treat it, or if it's permanent. All they can do is advise us to be vigilant and follow basic tick-avoidance practices.

The Right Way to Clean Your Face Mask

In an effort to slow the transmission of coronavirus in public settings, health officials are advising that people unable to practice social distancing wear a cloth face mask. While not as effective at filtering respiratory droplets as medical-grade masks, cloth masks are still recommended as a practical preventative step.

Like all apparel, masks get dirty. They absorb sweat and germs, and they need to be cleaned. But how?

According to National Geographic, the best way to clean a cloth face mask is to take the same approach as the rest of your laundry—toss it in the washer. Laundry detergent is effective against coronavirus because the pathogen is encased in a layer of oily lipids and proteins. Detergents and hand soaps contain surfactants, which reduce the surface tension of the fatty layer. The surfactant molecule is attracted to oil and grease on one end and water on the other. The end that disrupts the oil bursts the coronavirus envelope apart. Tiny pods of surfactant called micelles trap and wash the remnants away. It’s this activity, not the water temperature, that kills the virus, though using a higher dryer temperature can destroy most microorganisms that might be lingering.

Bear in mind there’s a recommended way to take off your mask. Make sure your hands are clean, then pull it off using the straps behind your ears. This avoids contaminating the mask—and your face—with any pathogens that might be on your hands.

Medical-grade masks are trickier, as they’re intended to be used only once and can’t stand up to a wash cycle. If you have an N95 or paper mask, you can set it aside for several days, at which point the virus is likely to become inactive. But keep in mind that health officials still aren’t entirely sure how long coronavirus can persist on surfaces, and it’s possible for a mask to collect particles over time, increasing the viral load.

But what about the rest of your clothes? Experts say not to worry so much about disrobing the minute you get home. The coronavirus likes moisture and dries out quickly on fabrics. You need to be careful with the material covering your face, but the rest of your outfit can wait until your regularly scheduled laundry appointment.
