Attention Moscow Mule Fans: Those Copper Mugs May Pose a Serious Health Threat

Even if you can’t list the ingredients in a Moscow Mule, you may be able to recognize one from across a bar: The simple combination of vodka, lime juice, and ginger beer is traditionally served in a copper mug. But that trendy vessel could pose a serious health threat, according to public health officials. As CBS News reports, the potential for food poisoning from those iconic cups is severe enough that the state of Iowa is taking a stand against them.

Copper is commonly used to make kitchenware like pots and pans, but when it comes into contact with certain foods, it can be unsafe. Foods and liquids that have a pH lower than 6.0, and are therefore acidic, can erode the copper and copper alloys and cause them to mix with whatever’s being consumed. The pH of lime juice falls between 2.0 and 2.35 [PDF], so the chances of copper contamination from a Moscow Mule sloshing inside a copper mug all night are high.

Symptoms of copper poisoning include vomiting, abdominal pain, diarrhea, and yellow skin or jaundice. Even if you feel fine after a night of Moscow Mule imbibing, long-term effects like liver damage can occur over time. In response to these hazards, Iowa’s Alcoholic Beverages Division released a statement [PDF] advising against the use of Moscow Mule mugs. “The recent popularity of Moscow Mules, an alcoholic cocktail typically served in a copper mug, has led to inquiries regarding the safe use of copper mugs and this beverage,” it reads. “The use of copper and copper alloys as a food contact surface is limited in Iowa.”

If you’re hesitant to put your Moscow Mule obsession to bed, there are ways to enjoy the drink safely without sacrificing the classic look. When stocking your bar at home, make sure to include copper mugs lined with food-safe metal like nickel or stainless steel. And when you’re ordering the drink elsewhere, you can check with the bartender to see if they have similar containers. If not, asking for the drink in a boring old glass is your safest bet.

The Very Disgusting Reason You Should Always Wash New Clothes Before Wearing Them

It’s sometimes assumed that clothing with a price tag still dangling from the sleeve can skip an initial wash. Someone else may have tried it on, sure, but they didn’t run a marathon in it. Why not just throw it in the closet as soon as you get home?

One big reason: lice. As The Independent reports, Donald Belsito, a professor of dermatology at Columbia University Medical Center, told NBC's Today show recently that clothing fresh off store racks can harbor infestations of lice, scabies, or fungus.

You might be familiar with head lice as the dreaded insects that occupy the scalp and give school health monitors cause for concern. Head lice can be transmitted via clothing and other fabrics, and anyone who tried on a shirt or dress before you did can be a carrier. While they only live for one or two days without a blood meal, that’s still enough time to cause problems if something is being tried on frequently.

Scabies is far more insidious. The mites are too small to see, but the allergic reaction they cause by burrowing into your skin to lay eggs will be obvious.

Both scabies and lice can be treated with topical solutions, but it’s better to kill them by washing new clothes in hot water. A good soak can also get rid of formaldehyde, a common chemical used in fabrics to help ward off mold in case stock gets wet in transit. Formaldehyde can cause allergic skin reactions. For all of these reasons, it’s best to hit the washing machine before those new pants ever hit your hanger.

How Promoting Handwashing Got One 19th Century Doctor Institutionalized

Regardless of how often we actually do it, it's common knowledge that washing our hands before eating, after coughing, and after using the bathroom is good for us. But the connection between handwashing and health wasn't always accepted as fact. As Danielle Bainbridge explains in the PBS web series Origin of Everything, the first doctor to campaign for cleanliness in hospitals was not only shunned by other medical professionals, but ended up in an insane asylum.

Prior to the 19th century, handwashing primarily existed in the context of religious ceremonies and practices. It plays a role in Christianity, Islam, Judaism, Sikhism, and Buddhism in some form or another. But washing up to stop the spread of disease wasn't really a thing for most of history. People weren't aware of germs, so instead of microbes, they blamed illness on everything from demons to bad air.

Then, in 1846, a Hungarian doctor named Ignaz Semmelweis made a breakthrough observation. He noticed that women giving birth with the help of midwives were less likely to die than those treated by doctors. He determined that because doctors were also performing autopsies on victims of puerperal fever (a bacterial infection also known as childbed fever), they were somehow spreading the disease to their other patients. Semmelweis started promoting handwashing and instrument sterilization in his clinic, and the spread of puerperal fever dropped as a result.

Despite the evidence to support his theory, his peers in the medical community weren't keen on the idea of blaming patient deaths on doctors. Partly due to his commitment to the controversial theory, Semmelweis was shunned from his field. He suffered a mental breakdown and ended up in a mental hospital, where he died a few weeks later.

Germ theory did eventually become more mainstream as the century progressed, and washing hands as a way to kill unseen pathogens started gaining popularity. Even so, it wasn't until the 1980s that the CDC released the first official guidelines instructing people on best handwashing practices.

If this story suddenly has you in the mood to practice good hygiene, here's the best way to wash your hands, according to experts.
