The state of Indiana has issued an outbreak alert due to E. coli due to the sickening of about 10 people in an Indiana elementary school (seven schoolchildren included), although school cafeteria food has now been ruled out as a possible cause.

With the Topps meat recall still fresh on the minds of millions after this past week's E.coli situation, Indiana officials made an adamant statement that its recall did not originate in the suspect school's cafeteria.

So far, at least three of the cases appear to have been caused from exposure to a sick family member -- but what about the others? This may be a case of spreading through human contact (direct or indirect) instead of food contamination.
