Tpms

i popped into a pet store i,ve not visited before and in the freezer section i found green tripe (tpms).
Ihave always got my tripe and other stuff from albion meats,but since the new EU rules the tripe from there is washed.
Before i go changing supplier i would like to know what the quality of tpms other stuff is like(store only had tripe).
Anyone here use them?
