Police in eastern Austria say a 39-year-old suspect has been arrested after rat poison turned up in some HiPP baby food jars on supermarket shelves in central Europe. The company recalled some of its baby food in Austria, the Czech Republic and Slovakia after the case came to light last month. It said in a statement Saturday it was “greatly relieved” by the arrest. Authorities said previously they believe the tampering occurred in 6.7-ounce jars of baby food made with carrots and potatoes for 5-month-olds that were sold from SPAR supermarkets in Austria.
