This is going to be the summer of the egg shortage.

Not to be hyperbolic about it, but when more than 35 million hens have to be destroyed in order to keep an avian flu outbreak in check, an egg shortage is inevitable.

This week, Whataburger announced that it would be restricting its breakfast hours because of the shortage, but the real canary in the coal mine came yesterday, when H-E-B stores across the state posted a sign saying that customers could only buy 3 cartons of eggs at a time. That’s 3 cartons of any size, store officials say, and it’s in an effort to ensure everyone can have access to buy some eggs. They have also restricted commercial sales.

The San Antonio-based grocer has not said how long the restrictions would be in place and it did not make an official announcement about the change, but officials did post this sign in stores:

H-E-B customers are our top priority, to ensure the availability of eggs for all Texas families, eggs are not available for commercial sale. The purchase of eggs is limited to 3 cartons per customer.

We apologize for any inconvenience.
