With poultry, much of the problem comes from the method of slaughter. With a small operator or butcher, they split and ress out poultry carefully..avoiding the entrails being broken and and contaminating the meat. Some of the huge processing plants split poultry on fine piano wires..dragging smashed entrails through the carcase. The processor then relys upon a water/formaldehyde mix to wash the carcase clean..taking several washes to accomplish the task.
Better to not get the carcase contaminated to start with (IMO).
Of course, the precautions given by Swampy...should be universally observed, no matter where you acquired the meat.
