# Heatwave strains Parmigiano industry and fuels wildfires > Live situation record from CLSTR: https://clstr.news/situations/italian-parmigiano-reggiano-cheese-industry > Updated: 2026-08-21T12:00:04.000Z. Sources: 157. Developments: 17. The July–August 2026 heatwave across Europe, with temperatures exceeding 45 °C, has severely strained the Parmigiano Reggiano industry and exacerbated wildfire-driven pollution. The heatwave caused milk yields to drop as cattle reduced feed intake, threatening the €4.5 billion sector. This climate pressure is specifically impacting Italy’s unique financial system, where Credito Emiliano (Credem) has used Parmigiano Reggiano wheels as loan collateral since 1953. The bank typically advances 60% to 80% of a wheel's value to help farmers cover operational expenses during the 12 to 36-month aging process. To protect these assets, producers and banks have increased electricity use by roughly 30% for 24-hour ventilation and mist-cooling systems, necessitating new investments in upgraded cooling, insulation, and renewable energy. While blockchain technology has recently modernized the sector by allowing farmers to pledge cheese while it remains in their own facilities, the industry remains vulnerable to rising operational costs. Amidst these pressures, social media reports claiming a ‘Great Parmesan Crisis’ regarding the stability of cheese banks have been identified as misinformation. Giancarlo Ravanetti, general manager of Magazini Generali delle Tagliate (MGT), confirmed that operations remain normal and the 500,000 cheese wheels valued at 300 million euros are being aged under optimal conditions. Simultaneously, intense wildfires in France and Spain released approximately 18 million metric tonnes of CO₂ and generated hazardous PM2.5 smoke plumes. Amidst these pressures, the Italian agro-food sector remains concerned regarding ‘Italian sounding’ fraud and US legislation regarding ‘common names’ for protected cheeses. ## Claims - Wildfires in France and Spain have exposed millions of people to health‑damaging air pollution.
