As for pork, prices were down an average 1.4 percent in June from a year ago, but were up 1.2 percent from May. The USDA is looking for pork prices to fall between 0.5 percent and 1.5 percent this year, a moderation from the 3.9 percent average decline tracked in 2015. Pork prices over the last 20 years have seen inflation on average of about 2.5 percent.
Poultry prices fell an average of 3.4 percent in June from the year-ago period and dropped 0.5 percent from May. The government sees poultry prices flat to down 1 percent in 2016, below the category's 20-year historical average of 2.6 percent inflation.
Tyson Foods is scheduled to report its fiscal third-quarter earnings Monday, and analysts estimate its poultry division sales will be down slightly from a year ago due to pricing declines, reflecting in part lower breast meat prices.
Stephens analyst Farha Aslam estimates that chicken breast prices in the June quarter were averaging down more than 20 percent on a year-over-year basis. Chicken wing prices averaged more moderate price declines in the quarter, although the wing prices are likely to take flight again.
"Wing prices are expected to head higher as we near the beginning of football season," said Aslam in a note Tuesday. "Prices are expected to peak around the Super Bowl and will likely be supported through March Madness reflecting the typical season trends."
In the dairy aisle, prices fell an average of 2.2 percent in June from the year-ago period and around 0.6 percent from average prices in May. For the year, the USDA is forecasting dairy prices will decline on average between 0.5 percent and 1.5 percent. Last year, dairy prices fell on average 1.3 percent compared with the category's 20-year historical average for inflation of 2.7 percent.
Dean Foods, the nation's top milk producer, is set to report second-quarter results on Monday and analysts expect sales will be down 8 percent, in part due to lower milk pricing.
A USDA retail dairy report released Friday found even the single-most advertised dairy item — a container of conventional Greek yogurt — was slightly lower in price during the latest survey week compared with the prior week. Greek yogurt is a top-selling product within the dairy aisle.
Not all food is going lower, particularly when it comes to fresh produce.
Fresh fruits and vegetables are forecast to show price inflation this year of 2 percent to 3 percent, according to the government. In 2015, the category averaged a 0.5 percent decline.
Fresh vegetable inflation is seen slightly higher than fruits this year, and that is consistent with 2015 trends when the average prices of fresh fruits were estimated to be down 2.2 percent.
Even processed fruits and vegetables are forecast to have price inflation this year, between 1 percent and 2 percent. Still, that is below the 20-year historical average of 2.6 percent price inflation for the category.
