美国鸡蛋价格近期有所下降,但仍高于两年前的水平。文章探讨了鸡蛋价格上涨的多个因素,包括季节性需求、禽流感疫情、加州等州的无笼鸡蛋要求以及气候变化等。禽流感疫情导致大量家禽被扑杀,减少了鸡蛋供应,而无笼鸡蛋的需求也增加了禽流感传播的风险。此外,气候变化导致野生鸟类迁徙路线改变,增加了禽流感传播的可能性。尽管饲料价格下降,但鸡蛋行业仍在努力重建鸡群,这可能会限制鸡蛋供应。文章指出,鸡蛋价格上涨并非超市单方面导致,而是多种因素综合作用的结果。

🐔**季节性需求:** 鸡蛋需求在11月和12月达到峰值,因为节假日烘焙需要大量鸡蛋,导致价格上涨。

🦠**禽流感疫情:** 2022年2月开始的禽流感疫情导致超过1.11亿只家禽被扑杀,其中大部分是产蛋鸡,减少了鸡蛋供应,导致价格上涨。

🥚**无笼鸡蛋要求:** 加州等州要求鸡蛋必须来自无笼鸡,而禽流感更容易在自由放养的鸡群中传播,导致无笼鸡蛋供应紧张,价格上涨。

🌪️**气候变化:** 气候变化导致极端天气频发,野生鸟类迁徙路线发生变化,增加了禽流感传播的可能性,进一步影响鸡蛋供应。

💰**饲料价格下降:** 鸡饲料价格下降,为蛋鸡养殖降低了成本,但重建鸡群需要时间,可能会限制鸡蛋供应。

But prices are still far from the recent peak they reached almost two years ago. And the American Egg Board, a trade group, says egg shortages at grocery stores have been isolated and temporary so far.“Those are being rapidly corrected, sometimes within a day,” said Emily Metz, the Egg Board’s president and chief executive officer.The average price for a dozen eggs in U.S. cities was $3.37 in October, according to the Bureau of Labor Statistics. That was down slightly from September, and down significantly from January 2023, when the average price soared to $4.82. But it was up 63% from October 2023, when a dozen eggs cost an average of $2.07.Sometimes, supermarkets may be to blame for price spikes. During testimony in August in the Federal Trade Commission’s case seeking to block Kroger’s merger with Albertsons, Kroger’s senior director for pricing acknowledged that the company has raised the cost of milk and eggs beyond the levels of inflation.But there are other factors behind the price increases. Metz said the egg industry sees its highest demand in November and December, for example.“You can’t have your holiday baking, your pumpkin pie, your stuffing, without eggs,” she said.Avian influenza is another big reason for the higher prices. The current bird flu outbreak that began in February 2022 has led to the slaughter of more than 111 million birds, mostly egg-laying chickens. Anytime the virus is found, every bird on a farm is killed to limit the spread of the disease.More than 6 million birds have been slaughtered just this month because of bird flu. They were a relatively small part of the total U.S. egg-laying flock of 377 million chickens. Still, the flock is down about 3% over the past year, contributing to a 4% drop in egg production, according to the U.S. Department of Agriculture.The latest wave of bird flu is scrambling supplies of cage-free eggs because California has been among the hardest hit states. California, Nevada, Washington and Oregon all require eggs sold in their states to be cage-free.“We’re having to move eggs from other areas of the country that are producing cage-free to cover that low supply in those states, because those states only allow for cage-free eggs to be sold,” Metz said.Cage-free requirements are set to go into effect in Arizona, Colorado and Michigan next year and in Rhode Island and Utah in 2030.Demand for such specialty eggs may also be contributing to avian flu, which is spread through the droppings of wild birds as they migrate past farms. Allowing chickens to roam more freely puts them at greater risk, said Chad Hart, a professor and agricultural economist at Iowa State University.“It’s really hard to control that interaction between domesticated birds and wild birds,” Hart said. “Some of those vectors have been opened up because we’re asking the egg industry to produce in ways that we didn’t ask them to before.”Metz said climate change and extreme weather are also blowing some wild birds off course.“We have birds that have been displaced by hurricanes, by wildfires, and those birds are now circulating in areas that they otherwise might not circulate or at times of the year that they otherwise may not be circulating,” she said. “And those are all new variables that our farmers are having to deal with.”Hart said the egg industry is trying to rebuild the flock, but that also can limit supplies, since farmers have to hold back some eggs to hatch into new chickens.Still, there is some good news on U.S. poultry farms. The price of chicken feed — which represents 70% of a farmer’s costs — has fallen significantly after doubling between 2020 and 2022, Hart said.___Durbin reported from Detroit.
