how long can I leave newly canned tomatoes before checking seal?

13 years ago

I am planning on canning my tomatoes tomorrow morning. It's my first time canning. I am canning whole tomatoes in tomato sauce with a newly purchased pressure canner. I hope to finish by the afternoon, then leave town until Monday evening. I read the instructions, which say to check jar seals 12-24 hours after processing. Is it OK to wait 48 hrs before checking?
