The Health Department says that tests have confirmed that E. coli outbreak has come from cooked meat at "The Grill" at the Meat Market in Northwest Fresno.

Tests on leftovers have confirmed a viral strain of E. coli was present in that meat. The same strain was found in at least 11 of the victims.

The Grill is voluntarily recalling the cooked tri-tip meat.

The Health Department is not clear on how the contamination occurred. Their investigation is still underway. However, they say the meat could have come to the Meat Market contaminated from the packing house, perhaps it wasn’t cooked enough or the contamination could have happened during contamination after it was cooked.
