Rabbit... not in my experience. I bought some pull top cans of fruit cocktail, peaches and pears, all in 2014. We used the last of them last fall... I never did have a can failure. I do suspect they would be less tolerant of being dropped...I am so terrible at canning peaches I've quit. I have started buying store-bought canned peaches but I have been avoiding the cans that have the pull-top lid openings. Are these cans weaker when it comes to longer than their use by date storage?
