McDonald’s Corp. is taking to social media to dispel rumors that its food is unhealthy and to explain why its burgers remain intact for weeks out in the open.

The fast-food chain launched a Q&A style advertising blitz on YouTube, Facebook and Twitter and its own website to answer questions from consumers about its food. As part of the campaign, the company has hired Grant Imahara, the former co-host of “Mythbusters,” to visit McDonald’s restaurants and suppliers around the country.

The chain is taking a more hands-on approach to correct what it views as misconceptions about its food as the company struggles with declining same-store sales. In September, McDonald’s reported its sharpest drop in global same-stores sales in more than a decade.

On the McDonald’s homepage, the chain had tried to directly address some of the most persistent rumors, videos and pictures that have circulated online regarding the quality of its food.

In response to experiments that show its burgers can stay intact for weeks or even years without rotting, the company explained that food that has been dehydrated cannot form mold and will simply dry out. “Sort of like bread left out on a counter overnight to make croutons for stuffing,” the company explained.

McDonald’s displayed less tolerance and more sass for some of the more outlandish myths about its food.

One question – “Does McDonald’s beef contain worms” – prompted this brief response: “No. Gross! End of story.”
