Blue Bell Creameries has signed agreements with health officials in Texas and Oklahoma requiring the company to inform the states whenever there is a positive test result for listeria in its products or ingredients.

The Colorado farmers who distributed cantaloupes infected with listeria two years ago pleaded guilty in federal court to criminal charges Tuesday. Jensen Farms, located outside Holly, Colo., was the source of the outbreak that killed 33 people nationwide.

The outbreak was the deadliest in more than 20 years. Cantaloupes processed in the summer of 2011 at Jensen Farms near the Kansas border were laden with Listeria. It’s a pathogen infamous for its high mortality rate.
