Food Safety Tip: Mind the Sneeze Guard!

He might be the most powerful man on Earth and ultimately responsible for America's food safety regulators, but even President Barack Obama can make a food safety faux pas.

As seen in the June 23 photo above, the president visited a restaurant where he leaned over the "sneeze guard" to choose toppings for his burrito, a fact the news media and Twitterverse were quick to point out.

According to Smithsonian Magazine, the sneeze guard was invented in 1959 by a germaphobe restaurateur named Johnny Garneau, which he dubbed a "Food Service Table" in the patent application. The device eventually became a nationwide legal mandate at all self-service food bars.

In addition to bodily emanations, sneeze guards can protect food from other threats like stray hairs. And presidents.
