Austrian police have issued a warning about potentially poisoned HiPP baby food after a sample tested positive for rat poison. The contaminated jar was found in Eisenstadt, prompting HiPP to recall all jarred purées sold in Spar supermarkets. Authorities are urging parents to be vigilant and check for signs of tampering. Similar issues have been reported in the Czech Republic and Slovakia, and previous recalls of baby formula by other brands have occurred due to contamination fears.
