doodoo capsules ( not rice )

Parasites Forum 01 doodoo capsules. What are these? That is a chop stick in the pic so you can know the size. They are sorta 'rubbery'. I could 'pop' one of them. They are not white & not rice shape. They are a tan/ barley color & sorta shaped like a vitamin e pill. I am not taking any pills or eating any grains.
