Issue Areas/Comments
There is one safety issue that should be addressed before cloned animal products are introduced to the food supply. Namely, it is possible for laboratory manipulation of cells in culture to introduce contaminant viruses or prions into the cell lines, which would then enter the population of agricultural animals at large. In a worst-case scenario, this could effect the health of livestock and of consumers. This risk needs to be addressed at its source, the individual cloning lab, by installing safeguards including clean handling procedures for the cell lines used, appropriate sourcing and contamination testing standards for the culture media and reagents used, and rigorous testing of the animals produced for signs of viral or prion contamination.

Similar safety issues exist for the laboratory culture techniques used in some kinds of vaccine production, so I'd imagine the FDA already has the in house expertise to address this risk as it regards the cloned animal issue.

Thanks for listening!
