Ever since I started working with fish a few months ago, this has started happening. I will go home and either that night or the next night, I will notice a fishy odor. However, a few days later, if I am not working, and my pants are washed, the smell goes away. Again, this has only started happening since I began working with the fish, I don't like any fish, except for crustaceans, and it is VERY rare that I will eat them. Any help?
