As you may have heard, there has been a massive, ongoing egg recall.
For your panicking pleasure, here are the latest details from the FDA:
Basically, you should check your fridge for the recalled companies and lot numbers.
You should also cook eggs thoroughly (particularly for your kids!) and and wash your hands after before and after handling eggs (though, you should really do that whenever you are handling food.)
Oh, and buy organic and all-natural eggs doesn't hurt–the recall doesn't seem to be affecting those companies.
