Our treats are produced in FDA/USDA approved plants that have either food standards or the highest standard for pet food (GFSI). None of our treats have a pledge for irradiation.  Our plant is approved for export to Canada and Korea, where we have to meet the following standards. All poultry is heated over 57°C for 14 minutes , and/or 74°C for 5 minutes. All Bovinae(Cattle) is heated to 70°C for 30 minutes ,79°C for 30 seconds or 90°C internal temperature.  Fish items and Dairy items have no time/temperature requirements, since our fish drying has a better result at lower temperatures.  Sweet Potatoes we can dry under 115°F so they can have the RAW stamp on them ,  however we have heated them up to 125°F. Irradiation,is something we have talked about doing , by microwaves , but since our raw materials are sourced , produced in highest standard plants , we don't see immediate need for doing that at this time.
