Retail pork prices rose by 3.1% in July, according to the RPI index, compared with a year ago says the latest BPEX quarterly category report.
However, prices paid to producers have not increased and most pig producers are still operating on a negative margin.
With pig prices now falling again, they will continue to be in this position for the immediate future.
As well as looking at the overall market, the report, produced by the AHDB Consumer Insight team, drills down into the detail of sales of fresh pork, bacon and sausages and ham.
Consumer Insight Manager Richard Cullen said: "British households spent on average 65p more on fresh pork compared to the same 12-week period last year.
"At the same time pork continues to be the best-performing red meat though the increased volumes in the latest year have been driven by promotions."
