Extreme heatwaves in northern Italy are threatening the production of Parmigiano Reggiano by degrading milk quality and increasing storage costs.
This environmental stress puts one of Italy's most famous exports at risk, impacting both the immediate quality of the dairy and the long-term viability of the aging process. Because the cheese requires precise conditions to mature, sudden temperature spikes can jeopardize the entire inventory.
The crisis is centered in the Emilia-Romagna region, with particular impacts noted around Montecavolo and Medesano [1, 2]. Producers are struggling to maintain the strict standards required for the protected designation of origin status while battling soaring temperatures.
The financial stakes are significant. More than 500,000 wheels of cheese are currently at risk [1]. The estimated value of this endangered inventory is approximately €300 million [1].
Industry reports said the heat affects the process at two primary stages. First, extreme temperatures reduce the quality of the milk provided by cows, which serves as the raw material for the cheese [1, 2]. Second, the heat increases the costs associated with storing the wheels to ensure they do not spoil during the maturation phase [1, 2].
Producers in the heartland of Parmesan production are now facing a dual challenge of managing livestock health in the heat while investing in cooling infrastructure to protect their assets [1, 2].
“More than 500,000 wheels of cheese are currently at risk”
The vulnerability of Parmigiano Reggiano to temperature swings highlights a growing systemic risk for traditional European agricultural products. As climate volatility increases, the cost of maintaining 'protected' geographical standards rises, potentially leading to higher consumer prices or a decrease in the availability of authentic regional cheeses.
