Researchers have discovered how salmonella and E.coli germs – more commonly associated with chicken and bovine products – can spread to salad and vegetable leaves.
A salmonella outbreak in the UK last year was traced back to imported basil while an E.coli outbreak in America in 2006 was linked back to pre-packed baby spinach.
Professor Gadi Frankel, from Imperial College, said consumers needed to be aware of the risk of contaminated salad to avoid potential food poisoning.
