There are hundreds of frozen products available at retail containing potentially hazardous food; some are fully cooked; some aren’t.
This is one example. The Kroger Chicken Kiev label states it’s "Microwavable," but also says, UNCOOKED; Keep Frozen; Cook to an Internal Temperature of 165F as measured by a thermometer."
On the back, the microwave instructions say the time estimates are for a 1,000 W microwave, which is more specific than the high, medium or low on the ConAgra Banquet pot pies. I found out our microwave is 1150 W, but don’t know if that is high, medium or low.
