McDonald's is shedding new light on its often-criticized food sourcing and processing practices.

In the face of growing consumer demand for transparency, the Big Mac chain has launched social media campaigns in Canada and Australia to answer consumer- submitted questions like, "Are McDonald's eggs organic or free-range?" and, "Does McDonald's import beef from other countries?"

McDonald's has also added a "Your Questions Answered" section to its US website addressing various customer concerns, including the rumored existence of "pink slime" in its meat and information about which egg dishes are cooked in the restaurant and which ones are premade and frozen.

We have selected some of the most commonly asked questions and provided summaries of the company's responses.
