Colorado has logged more than 250 salmonella cases so far this month, roughly a hundred above what the state normally sees, and public health investigators have not identified what is causing it. More than 250 reported Salmonella cases in Colorado in July. When a laboratory confirms Salmonella in a patient sample, Colorado requires the isolate to be submitted to the state public health laboratory for confirmation and sequencing. What This Is NotThere is a national salmonella outbreak running right now, and conflating the two would be a mistake. The confirmed facts are that Colorado has recorded more than 250 salmonella cases in July, about a hundred above average, and that no food, restaurant or supplier has been identified.
