I accidentally added both the separate meats together in the slow cooker last night and wanted to know if I completely ruined it and should just toss it. I tried it and personally thought it was okay.
"I tried it and personally thought it was okay."
You answered your own question. You found the end result to be satisfactory, you should feel comfortable putting on your table.
From a food safety standpoint, there is no health danger as your slow cooker sanitized your dish.
Enjoy your concoction!
