People are hoarding Costco eggs, hundreds at a time.

Eggs have been a sold-out commodity at supermarkets across the city, and country, but they were plentiful Tuesday morning at San Francisco’s Costco. Shoppers came prepared to make the most of the bounty — the likes of which they may not see again for a long time.

Eager customers showed up at the big-box store at 9 a.m. and dashed to the egg fridges. The shopping-cart-pushing cast included restaurant staffers, fitness fanatics, and anyone else who’s had their breakfast dreams smashed at the sight of depleted stocks elsewhere.

Shoppers said it’s been difficult to get eggs at other supermarkets as bird flu has wreaked havoc on poultry farms.

The Department of Agriculture’s Animal and Plant Health Inspection Service confirmed highly pathogenic avian flu in a commercial flock for the first time on Feb. 8, 2022, three years ago this week. According to government data, as of Monday, there have been four affected commercial flocks and two affected backyard flocks in California and a total of 387,710 birds affected in this outbreak.
