it is roasted not fried (roasted- no oil, fried- with oil) roasting just removes the water content, example-- beef jerky. if it was not roasted you would be wrapping sushi with raw algae. check it next time it's roasted. i have feed this nori to my tang for the last two years with no ill effect. compare the contents in both the package at the pet store and grocery store, you will find it the same. try it!
