I know all about those little red tomato skin looking things. The first time I experienced them was when I was doing a six-week-long hardcore Miracle-Mineral-Supplement (8 hours daily on the hour) and at the time, being unschooled in parasites, I didn't know what they were frankly - but like you, I knew I hadn't eaten any tomatoes.
So, I just finished up Humaworm for 30 days, and then coffee enemas, and an Miracle-Mineral-Supplement enema and have seen more of those. Finally looked it up and so many other people have seen them and wonder the same thing.
Hulda Clark calls them liver flukes and I tend to think she's right. I haven't seen any lately, which I'm hoping means they're finally flushing out. I think when they explode they roll up like tomato peels.
Thanks for this info because I've been wondering about the liver flush, getting ready to do my first one. My gallbladder area is tender from doing coffee enemas, and I passed two tiny little hard-as-rock stones today so that must be why.
