In a move to finally put rumors on the contents of its menu to rest, global fast-food chain McDonald's has enlisted the help of former "Mythbuster" host Grant Imahara to answer various questions on its menu.

According to Business Week, one of the biggest questions during the "Our food. Your questions" campaign was regarding the beef patty.

"Is your beef real?" asked one curious individual. "It's 100 per cent beef trimmings," quoted Fox News of the response of Cargill Operations Supervisor Jimmy Rendon. 

Another question posted was, "Why doesn't your food rot?" wrote CNN Money. It seems the question was related to the 2004 documentary of CNN's Morgan Spurlock titled, "Super Size Me."

"McDonald's insists that its food can, in fact, rot," noted CNN, and explained to viewers: "You might have seen experiments which seem to show no decomposition in our food. Most likely, this is because the food has dehydrated before any visible deterioration could occur."

The campaign was launched to finally address some of the food-quality concerns the company, along with other fast-food chains have been hit with recently. 

According to Fox, the move is a first for McDonald's, which has never allowed cameras in its U.S. food plants.

The segment took the "Mythbusters" co-host Imahara and his video crew to Fresno's Cargill plant to see first hand what really happens in the production line of McDonald's hamburgers.

Explaining that this campaign was done to increase transparancy with its customers, Kevin Newell, EVP-chief brand and strategy officer for McDonald's USA told BurgerBusiness.com, via Huffpost: "We know some people--both McDonald's fans and skeptics--continue to have questions about our food from the standpoint of the ingredients or how food is prepared at the restaurant. This is our move to ensure we engage people in a two-way dialogue about our food and answer the questions and address their comments."

The difference this time around? He explains: "We've made nutrition information about our food available for a number of years. But people had to go find it. Now we're inviting consumers to go on a journey with us to get those questions answered."

The "Our Food. Your Questions" was launched earlier in Canada and Australia, making this the first move in the United States to promote more interaction between the company and customers with concerns.
