The above table shows that these are the food items that can be responsible for the attacks as when people consume them the frequency of getting ill is more as compared to when other person who do not consume them. The food item that seems to be causative of outbreak due to presence of contaminants is creamed whipped beef, because the people well when consuming them are very less as compared to the people who do not consume this food item. While rest food items have not much effect on the number of well people, consuming it or not.
