Cross-contamination occurs when gluten-free foods come into contact with foods that contain gluten. It can happen during the manufacturing process, for example, if the same equipment is used to make a variety of products. Some food labels include a may contain statement if cross-contamination is likely.
After getting a tattoo, swimming must be avoided until the skin has stopped peeling and all scabs have fallen off. For most people, this means waiting a minimum of two weeks.
I sincerely hope you are showering daily.....otherwise that would be scary. After getting a tattoo you should leave the bandage on for 1-2 hours and then you're good to go on showering. You can not submerge your tattoo in water but you can (and should) shower. You should be washing your tattoo at least once or twice a day. If you want to take a bath thats fine as long as you dont submerge the tattoo in water. After its done peeling there are no worries about water damage.
