If you’ve been grocery shopping recently, you may have noticed a lot of bare shelves in the egg section. And if you’ve managed to snag a carton, you probably spotted something even more shocking: the price.

Colorado shoppers looking for eggs are encountering price hikes and even empty shelves, with many local grocery stores displaying signs of shortages.

That’s also true of handling eggs, according to the Centers for Disease Control and Prevention (CDC). Government officials have put very strict surveillance in place for egg-laying hens across the U.S., making it very likely that infected poultry or eggs will be detected quickly.
