In the Campinas region of São Paulo, Brazil, the occurrence of food poisoning cases has increased significantly, with a staggering 40.2% rise documented from January to November 2025. According to data from the State Health Department, there were approximately 77,638 reported cases during this period, compared to 55,343 cases in the same timeframe in 2024. This ongoing trend has raised alarms among health officials as it denotes a persistent public health concern in the area.

The increase in food poisoning cases is notably attributed to the warmer months, particularly spring and summer, when high temperatures create conducive conditions for the growth of harmful microorganisms in food. The health authorities caution that these months are particularly risky for food conservation, which can lead to an uptick in foodborne illnesses. Symptoms such as diarrhea and vomiting are prevalent, and dehydration is a common complication that may necessitate hospitalization in severe instances.

As health officials strive to mitigate this issue, they recommend enhanced food safety measures and public awareness campaigns about proper food handling and storage, especially during hotter temperatures. This increase in food poisoning cases not only threatens public health but also underscores the need for ongoing vigilance and effective health strategies in the region as climate changes continue to pose risks for food safety.
