Max temp freezer meat can be kept at, and for how long?

People in the hospitality industry have what is called a temperature danger zone which is any temperature between 40 and 140 degrees fahrenheit. Foods should not be kept in this danger zone for more than four hours before being properly stored. That is: at or below 40 degrees for cold food or at or below 140 degrees for hot foods. Your meat has probably spoiled due to fluctuating temperatures. Freezing only slows bacterial growth, it doesn't kill it. The portion of your meat that is not frozen is still susceptible to bacterial growth. Best to be safe and pitch it.
