California pools must post a dizzying array of warnings, the best of which is "Persons having currently active diarrhea or who have had active diarrhea within the previous 14 days shall not be allowed to enter the pool water." Turns out there was a messy fight behind the now-ubiquitous nanny-state signage. Read the rest
Minneapolis-based Indeed Brewing company makes a seasonal beer called "Lavender, Sunflower Honey, Date Honey Ale." That's "LSD Ale" for short. It doesn't contain lysergic acid diethylamide, which is also sometime called LSD. But federal regulators have told Indeed Brewing that the illicit drug retains its sole right to use the acronym, so Indeed has to change its distinctive label.
Paste magazine says the ale has a "tingly kind of spice, like licking a 9-volt battery, but in a good way."
I guess the folks at Indeed Brewing don't have as much money and influence as fashion brand Yves Saint Laurent, which has been selling Opium since 1977. Read the rest
Back in September, the Centers for Disease Control and Prevention issued a report connecting the use of antibiotics in livestock to antibiotic resistance in humans. It was an important step in turning science into action. Although human use and misuse of antibiotics and the spread of antibiotic-resistant bacteria in hospitals are important parts of the puzzle of antibiotic resistance, the massive use of antibiotics by the agricultural industry also plays a key role. In fact, the vast majority of antibiotics used in the United States are used by animals. (Reasonable estimates range as high as 80%.)
What's more, the vast majority of that antibiotic use has nothing to do with the health of the animals. The antibiotics have the side effect of promoting weight gain. Important drugs like penicillin and tetracycline are regularly doled out to cows and pigs and chickens as part of their daily feed in order to make them fatter — a practice which has been shown to directly reduce those drugs' effectiveness at treating actual illness in humans. Today, the FDA announced that it plans to change this ... but there are problems. Read the rest
Every year, more than 2000 Americans experience a serious negative effect (either death or illness) from taking over-the-counter dietary supplements. Since 1994, it's been legal to sell supplements without prior safety testing. Even when someone gets sick, the burden of proof is on the FDA to prove the supplement caused it, rather than on the supplement company to prove it didn't. The Dallas Morning News
reports on the lack of oversight and what it costs us. Read the rest
The good news: Fecal transplants work well enough as a treatment for patients with Clostridium difficile
infections that the Food and Drug Administration has decided to take them out of the grey area of legality in which they were previously being performed
. Poop transplants for C. difficile
will be legal, and the doctors doing the transplants will have to be approved by the FDA, to make sure they're getting the donor poop through safe means and not prescribing poop transplants for things that poop transplants don't help. The bad news: The approval process turns out to be ridiculously arcane and time-consuming — featuring a 30-day waiting period and requirements that are apparently secret. Read the rest
Officials from the Peanut Corporation of America are being indicted for their roles in a 2009 salmonella outbreak that killed at least nine people. It's rare for this kind of prosecution to actually happen, writes Maryn McKenna at her Superbug blog. But, in this case, there's mounds of evidence that executives circumvented safety testing, ignored positive salmonella results, and pressured their employees to send out product even though it might be tainted. Here's the money quote, from PCA's former president, revealed in an email recovered by the prosecution: "Shit, just ship it." Read the rest
Short version: There is LOTS the FDA doesn't want to tell you about livestock antibiotic use. And that matters. As I reminded you yesterday, the antibiotics we use to keep ourselves alive and healthy are rapidly losing their effectiveness against a whole host of diseases
. Antibiotic resistance to disease is driven by overuse of antibiotics — both in humans and in animals. And there are lots of antibiotics being used on animals. The trouble is, public health researcher know very little about that use. Because the FDA refuses to release more than the bare minimum of data.
For added fun, last year, they stopped even trying to regulate antibiotic use on livestock — opting instead for voluntary self-control systems. Read the rest
It does successfully prevent sunburn, but what about the evidence for sunscreen protecting you from skin cancer later in life?
The answer: Nobody is really sure. Last year, I wrote a short piece for BoingBoing that looked at this a little bit. The key point: Cancer takes a long time to happen and we haven't been using sunscreen long enough to have much evidence about it.
But, at Discover's The Crux blog, Emily Elert expands on some of the other problems in play. One of the key things—and something that will hopefully be fixed by this time next year—there's nothing on the sunblock you buy to tell you how protective it is against skin cancer. SPF is all about the burn. So even if some sunscreens do protect against cancer, you don't have a good way to know whether or not you're using one of them.

First of all, the way sunscreen’s effectiveness is measured—its SPF rating—basically only describes its ability to block UVB rays. That’s because UVB is the main cause of sunburn, and a sunscreen’s SPF stands for how long you can stay in the sun without getting a sunburn (a lotion that allows you to spend 40 minutes in the sun rather than the usual 20 before burning, for example, has an SPF of 2).
UVA rays can cause cancer but not sunburn, so they don’t factor into the SPF calculation. That means that if you slather on a high SPF sunscreen that only protects against UVB, you’d still absorb lots of UVA radiation, potentially increasing your long-term cancer risk.
By 2025, US automakers will have to have an average fleet fuel economy of 52.5 miles per gallon. That standard is 27.3 mpg today, so it sounds like a great, big, scary leap. But not really, say vehicle technology experts. In fact, there's enough room for improvement in things like auto-body design, that we can meet the new goal without needing any major technological breakthroughs
