At least 30 people were admitted to Italian hospitals for suspected botulism poisoning after eating pesto produced by Bruzzone and Ferrari. All reported having consumed the same pesto. Samples of blood, urine, feces and pesto same were sent to the Ministry of Health, Rome, for analysis.

In 2012, the UK Food Standards Agency identified an outbreak of botulism linked to olives from Italy.
