On December 12, 2013, the Food and Drug administration asked the animal pharmaceutical industry to notify the agency in writing within 90 days of its intent to engage with the FDA as defined in Guidance 213. This request made by the FDA is another part of the plan to help phase out the use of medically important antimicrobials in food animals for food production purposes. As of March 12, 2014, the FDA stated that it has received responses from all the sponsors affected by Guidance 213 and they are in the process of reviewing and analyzing the responses. The response so far has been positive and encouraging to the agency. Read more here about how the industry is responding to Guidance 213.
