The regulator said on Thursday it was conducting checks at McDonald's outlets in the Moscow region, the Ural mountains regions of Sverdlovsk, Orenburg, Chelyabinsk and Perm, the central Voronezh region and the northwest Karelia region.
It also plans checks in the central Tambov region, the southern Krasnodar region and the Volga region of Udmurtia.
Checks began on instructions from the agency Rospotrebnadzor a day after several branches in Moscow were shuttered by the same agency.
Natalya Lukyantseva, an official of the regulator's branch in Sverdlovsk region, said checks had started following complaints from customers about the quality and safety of products in the fast-food chain.
“We cannot say at the moment the exact number of restaurants being checked,” she said. “Results will be announced soon.” McDonald's Russia office said the chain had eight restaurants in Yekaterinburg, Russia’s fourth-largest city and the Ural region's administrative centre.
Among a Russia-wide network of some 430 outlets, inspections would branch out to other locations, a Rospotrebnadzor statement added.

Snap inspections from August 18-20 revealed many violations of sanitary regulations, the agency said, adding that legal proceedings had begun ahead of court hearings.
Locations under scrutiny include the restaurant on Moscow's Pushkin Square, which McDonald's says is the busiest in its global network. This was the first to open in Russia, in 1990, seen as a symbol that the Cold War was ending.
Meanwhile, people queued in a long line on Thursday at the only McDonald's restaurant in the city of Izhevsk, near the Ural mountains.
“It is unusual to see such a long queue in the morning," a local driver told ITAR-TASS. "Obviously, people have been buying food for future use," he said.
Local Rospotrebnadzor officials said inspections might soon be conducted there.
