We are certainly being dupped!
After they are cut to size they are soaked in large vats of water mixed with chlorine to preserve them........ The same chlorine you use for your swimming pools. The reason for this is because they don't have the protection of the skin so they use a good amount of chlorine. Notice that after you have stored them in the fridge for a while , a white film forms on them.....it's the chlorine coming to the surface.
