I think it's important not to overcorrect here. The CDC issues all kinds of guidelines: wash your hands after petting a dog, always use a meat thermometer, definitely don't eat eggs with a runny yolk or raw cookie dough. (Less family friendly but more directly on point, they insist on dental dams for STD protection, which is probably even more widely ignored than the dog petting thing.) "Normal" doesn't mean the CDC will stop offering strict guidance on how to keep yourself healthy, it just means that most people feel okay slacking off on the parts that would be too annoying.
