Pulled my beef roast out of the slow cooker and saw these weird white stringy things poking out of the meat. They look like little worms or parasites. Is the meat infested?

the proper internal temperature and does not exhibit any signs of spoilage like a bad odor, unusual color, or slimy texture, it should be safe to eat. The white strings themselves are not harmful and are a normal part of the cooking process.

However, if you have any doubts about the safety of your meat due to its smell, color, or texture, it’s better to err on the side of caution and discard it. Food safety should always be a priority to prevent foodborne illness.
