John, you may be able to can the salsa under Wyoming’s cottage food law, assuming that your salsa has a pH of 4.6 or below. You would need to check with the ag dept (Dean – 307-777-6587 or Linda – 307-777-6592) to see if they would allow salsa in general, or if your product needs to be tested. You wouldn’t be able to sell the salsa uncanned.
You wouldn’t need to abide by any other state laws, but there may be local laws that you need to follow, such as getting a business license or another local permit. Check with your planning division to see if there are any other restrictions. Good luck!
