Pro Tip
If you can reveal a green, firm, brussel sprout center you can typically still eat the sprout. Just remove any leaves that are loose or show signs of decay, cut off the stems to reveal a fresh firm stem.
Cut the sprout in half and see what the center looks like. Use your best judgement on whether to eat or not.
If you are really unsure, it is always better to be safe rather than sorry, and you should toss or return your produce.
