A recent botulism outbreak in Indre-et-Loire, France, has been traced back to homemade pesto containing wild garlic.

The French Ministry of Health confirmed the presence of the botulinum bacteria in the pesto consumed by five individuals, four of whom are currently hospitalized.

Authorities are urgently tracking down 600 jars of the suspect pesto sold across France.

Botulism, a rare but severe neurological condition, can be fatal in 5% to 10% of cases.

It is caused by a potent toxin produced by bacteria in improperly preserved foods.

This incident highlights the risks associated with homemade preserves, a popular trend that has grown alongside the DIY culinary movement.

Health officials urge anyone who has consumed the pesto and experiences symptoms to seek medical attention immediately.
