Improper food storage raises risk of food poisoning in Italy

Summer heat in Italy is increasing cases of food‑borne illness as foods are stored at unsafe temperatures. Common bacterial pathogens include Salmonella, Clostridium botulinum, Bacillus cereus, Staphylococcus aureus and Listeria monocytogenes, which can proliferate when the cold chain is broken or foods remain in the 4 °C‑60 °C “danger zone.”

Symptoms range from nausea, vomiting, abdominal cramps and diarrhea to fever and muscle aches, with incubation periods varying from a few hours to several days depending on the organism. Most cases can be managed at home by rehydrating with water or oral rehydration solutions and resting; medical attention is needed for severe dehydration, blood in stool, or neurological signs such as double vision.

Prevention focuses on proper refrigeration, avoiding cross‑contamination, and ensuring that home‑canned or vacuum‑packed foods are processed correctly. The Istituto Superiore di Sanità advises keeping perishable items refrigerated below 4 °C, cooking meats thoroughly, and discarding foods left at room temperature for more than two hours.
