Question: Why does Rav Elyashiv say frozen chicken, even if it won’t defrost by itself in a room temperature room is not muktzah on Shabbos?
A. The Mishna Berura 308:31:125 says that there are people who eat or just swallow raw meat even if not salted. As long as the blood on the outside is washed off it is kosher because the blood on the inside is kosher until it comes out. Therefore, the raw meat is not muktzah. This type of meat that can be swallowed is dove or chick meat. Even if it is spoiled it is not muktzah because it can be eaten by the dogs.
B. Rav Shmuel Wasner poskins that if the meat was frozen then it is definitely muktzah if it won’t defrost until after shabbos.
Answer: If one can hasten the defrosting then it is not muktzah, for example by soaking it in water or putting it on a heating element like a heater or anything which wouldn’t cook it. (See Dirshu footnote #127, in the back page 31.)
