The tension between the U.S. and Russia may be rearing its head in an unlikely place. On Thursday, the Russian government began random sanitary inspections of McDonald's outlets throughout the country after four were shut down in Moscow. Russian officials said there had been complaints about food quality and did not provide more details, according to the Wall Street Journal. The timing of the inspection, however, overlaps with Russia's ban of food imports from Europe, Australia and the U.S., which includes meat and dairy products. McDonald's didn't comment on the ongoing inspection, but it said, "Serving our customers top-quality food remains our main priority." The McDonald's in Moscow's Pushkin Square had become a symbol of the end of the Cold War and over the years has evolved into a tourist attraction, but it now stands empty.
