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.

Netherlands Officials Want to Pay Residents to Bike to Work

Thinking about relocating to the Netherlands? You might also want to bring a bike. Government officials are looking to compensate residents for helping solve their traffic congestion problem and they want businesses to pay residents to bike to work, as The Independent reports.

Owing to automobile logjams on roadways that keep drivers stuck in their cars and cost the economy billions of euros annually, Dutch deputy infrastructure minister Stientje van Veldhoven recently told media that she's endorsing a program that would pay employees 19 cents for every kilometer (0.6 miles) they bike to work.

That doesn't sound like very much, but perhaps citizens who need to trek several miles each way would appreciate the cumulative boost in their weekly paychecks. For employers, the benefit would be a healthier workforce that might take fewer sick days and reduce parking needs.

Veldhoven says she also plans on designing a program that would assist employers in supplying workers with bicycles. The goal is to have 200,000 people opting for manual transportation over cars. If the program proceeds, it might find a receptive population. The Netherlands is already home to 22.5 million bikes, more than the 17.1 million people living there. In Amsterdam, a quarter of residents bike to work.

There's no timeline for implementing the pay-to-bike plan, but early trial studies indicate that the expense might not have to be a long-term prospect. Study subjects continued to bike to work even after the financial rewards stopped.

New Health-Monitoring Litter Box Could Save You a Trip to the Vet

Unsure if your cat is sick or just acting aloof per usual? A “smart toilet” for your fur baby could help you decide whether a trip to the vet is really necessary.

Enter the Pet Care Monitor: More than a litter box, the receptacle is designed to analyze cat urine for health issues, The Asahi Shimbun in Tokyo reports. Created by the Japan-based Sharp Corporation—better known for consumer electronics such as TVs, mobile phones, and the world's first LCD calculator—the product will be available for purchase on the company’s website starting July 30 (although shipping limitations may apply).

Sensors embedded in the monitor can measure your cat’s weight and urine volume, as well as the frequency and duration of toilet trips. That information is then analyzed by an AI program that compares it to data gleaned from a joint study between Sharp Corp and Tottori University in Japan. If there are any red flags, a report will be sent directly to your smartphone via an application called Cocoro Pet. The monitor could be especially useful for keeping an eye on cats with a history of kidney and urinary tract problems.

If you have several cats, the company offers sensors to identify each pet, allowing separate data sets to be collected and analyzed. (Each smart litter box can record the data of up to three cats.)

The Pet Care Monitor costs about $225, and there’s an additional monthly fee of roughly $3 for the service. Sharp Corporation says it will continue developing health products for pets, and it has already created a leg sensor that can tell if a dog is nervous by measuring its heart and respiratory rates.
