Four hidden reasons food prices are crazy right now

WASHINGTON - The Bureau of Labor Statistics revealed this month that prices for nearly all food categories at the grocery store have risen at rates not seen since the early 1980s. But shoppers already know that the cost of food has surged alarmingly, from the produce aisle to the meat counter and the freezer section.

Most consumers also know this is being driven by worker shortages, higher fuel costs and lingering supply-chain snarls from the pandemic. But other factors have emerged in recent weeks to push up that grocery bill. Here are four hidden reasons food prices have skyrocketed.

- The invasion of Ukraine. The war in Ukraine is having a huge impact on the cost of food in the United States - particularly the price of corn. The Chicago Board of Trade corn futures topped $8 a bushel earlier this week, reaching its highest price in nearly a decade.

The reasons are complex. Earlier this month, in hopes of limiting the spike in gas prices since Russia's invasion, the Biden administration announced it would allow high-ethanol gasoline to be sold this summer. High-ethanol gas is usually not allowed in summer months because of air pollution. But while the decision may ease some of the pain at the pump, it also contributes to rising food prices.

That's because corn is used to manufacture the ethanol. That corn would ordinarily be used for consumer goods and, crucially, animal feed. Because feed accounts for 60% of the costs associated with raising livestock, experts expect prices to rise for beef, pork and poultry, and even for some farmed fish.

Skyrocketing fertilizer prices linked to Russia's war in Ukraine are likely to contribute to higher meat prices in another way. Fertilizer is a significant, and sometimes the sole, source of the carbon dioxide used in the pre-slaughter stunning of animals, said Grady Ferguson, a research analyst for Gro Intelligence. Take that away and slaughter facilities need to find a different mechanism to humanely prepare animals.

But all this pressure could ultimately ease; many American farmers, who had planned to avoid corn this year to shield themselves from high fertilizer prices, may pivot back to reap the benefits of those high corn prices.

"Everything is in flux," said Lon Swanson, an agribusiness consultant for Wells Fargo.

- The avian flu. The worst avian flu outbreak in the United States since 2015 is causing a major spike in the price of chicken and turkey and an even more noticeable surge in egg prices.
