An adult has died with a confirmed case of the rare bacterial infection listeriosis after a massive recall of ready-made meals earlier this week.  

Health officials are investigating an “extensive outbreak” linked to the recall of supermarket ready meals, which were sold at retailers including Tesco, SuperValu, Aldi and Centra.
