ISIS leaders are reportedly asking its followers to carry out terror attacks by poisoning food in Western supermarkets, the Daily Mail reported Wednesday.
ISIS fanatics could be targeting British and US shops after the terror group perfected their methods using Iraqi prisoners as 'human guinea pigs'.
The details of the 'food poison tests' were uncovered in Mosul, Iraq, after the city was liberated from ISIS in July.
It is now feared that the ways of contaminating food could be used on a larger scale in attacks on the West.
It would not be the first time ISIS followers have sought to spread terror and death by using everyday objects as weapons.
In recent years, several deadly terror attacks have been carried out using large vehicles and cars, driving into crowds of people in public spaces.
Just last month, 13 people died and some 130 were injured when ISIS terrorists drove a white van down Barcelona's popular shopping street Las Ramblas.
Earlier this week, a two-year-long investigation by a British journalist found that ISIS had been using social media to find young, impressionable Muslims to carry out an attack in London.
