Investigations uncovered that sodium hydroxide and hydrogen peroxide was added to raw milk. These substances were used to mask the acidity caused by improper storage and microbial growth, rendering the milk unsuitable for market distribution.

The investigation also revealed that the dairy industry faced issues with milk preservation, as farmers often delivered milk with excessive microbial growth. This led to lactic acid production, lowering the milk's pH and compromising its quality. To counter this, one may add sodium hydroxide and hydrogen peroxide that are illegal to use in the European Union for food production. These chemicals were used to correct the pH of the milk and reduce bacterial loads, thus disguising the compromised state of the milk and allowing it to be processed into dairy products for mass distribution.

Authorities seizing 90 tons of milk and 110 tons of adulterated cheese, valued at over 800,000 euros. They also confiscated entire storage compartments, cold rooms, and expired products. The scandal has led to charges of food fraud and adulteration against 10 individuals and three companies involved in this complex scheme. This situation has raised significant concerns about food safety and the integrity of the dairy supply chain in the region, emphasizing the critical need for stringent oversight and vigilance to protect consumers from harmful food products.
