Here’s the question of the day: Do you believe there is food price deflation?

The reason I ask is the Wall Street Journal reports Food Price Deflation Cheers Consumers, Hurts Farmers, Grocers and Restaurants.

The U.S. is on track this year to post the longest stretch of falling food prices in more than 50 years, a streak that is cheering shoppers at the checkout line but putting a financial strain on farmers and grocery stores.

The trend is being fueled by an excess supply of dairy products, meat, grains and other staples and less demand for many of those same products from China and elsewhere due to the strong dollar. Lower energy costs for transportation and refrigeration also are contributing to sagging food prices, say economists.

“Deflation is a godsend for consumers,” said Bob Goldin, vice chairman of food consultancy Technomic Inc.

Nationwide, the price of a gallon of whole milk on average was down 11% to $3.06 in July over a year ago; the price of a dozen large eggs fell 40% to $1.55 in the same period.

The price of food at home is down 1.6% on a seasonally unadjusted basis in the 12 months through July, says the BLS.

Stephanie Hegre, a 46-year-old nanny in Thousand Oaks, Calif., has noticed a drop of about 10% in her weekly food shopping bill. Her 16-year-old twin daughters go through a lot of milk, meat and bread, adding up to an average weekly grocery bill of about $200.

“I feel it has dropped by $20 a week which, when you’re on a budget, is noticeable,” said Ms. Hegre, who has been stockpiling staples in case prices increase. “We freeze bread and buy two weeks’ worth of bacon at a time,” she said.

The glut is so severe in some places that dairy farmers have been dumping millions of pounds of excess milk onto fields. The U.S. Department of Agriculture just bought $20 million worth of cheese in response to hard-hit dairy farmers’ requests. The cheese was given to food banks and others through USDA nutrition-assistance programs
