The EU and regional authorities are helping cheese producers as dairy herds suffer in heat waves that are becoming the norm.

ROME — In the barns where the milk for Italy’s most famous cheese is produced, the fans have barely stopped whirring for two months. As temperatures across northern Italy push close to 40 degrees Celsius, cows stand almost motionless, tongues lolling, while automated sprinklers soak their backs.

Italy is now enduring its fourth major heat wave of an exceptionally brutal summer. The prolonged heat is piling costs on the €4 billion industry behind Parmigiano-Reggiano, forcing farmers to spend heavily on cooling their animals while drought and dwindling water supplies make it harder and more expensive to grow the forage needed to feed them.

Farmers have received support from regional authorities, the EU and a producers’ consortium to help them adapt to the heat, but they say the funding falls short of the investment increasingly required.

For producers of the protected cheese, there is no possibility of escaping somewhere cooler. Under the strict rules governing Parmigiano-Reggiano’s EU Protected Designation of Origin — that secures its added value on the market — the cows, their milk and the cheese must remain tied to a defined area of northern Italy. At least 75 percent of their forage must also be grown locally.
