(ABC News) - All the extreme heat across the U.S. in recent weeks may soon take a toll on Americans' wallets.
Wildfires out west and heat warnings in at least 22 states are not only difficult for people to deal with, but also for crops to handle.
Experts say the damage is already devastating. Less than half of the nation's corn is in good or excellent condition, sending prices up 37 percent since June 15.
"Of all the major crops that are growing in the United State, corn is the single most important for the food supply chain," said Ricky Volpe of the USDA.
That's because corn is used in several other products, including cereal and baked goods.
If the trend continues, food and commodity prices are expected to rise as much as 3.5 percent by the end of the year.
