DNA extraction from canned meat products can be a complicated process. The process of packaging food in cans generally involves a high-temperature sterilization process, which can degrade DNA. However, depending on the type of meat and the specific packaging process, it may be possible to extract some DNA. However, this DNA may not be in optimal conditions for certain types of analysis due to possible degradation. Remember that this is an assumption based on available information and may not be completely accurate.
