Austrian police have detained a suspect in connection with rat poison discovered in baby food jars on supermarket shelves. The tampering affected 6.7-ounce containers of carrot and potato baby food marketed for 5-month-old infants. Authorities confirmed the poisoning occurred before the products reached consumers. The case represents a serious public health threat and potential criminal endangerment. Police investigation continues into how the contamination happened and whether additional jars remain in circulation. Supermarkets removed affected batches from shelves following discovery of the poisoning. The incident has prompted heightened scrutiny of food safety protocols in retail environments across Austria.
