Explanation:

The vast majority of bacteria that produce gastrointestinal symptoms are transmitted via fecal-oral transmission. This means that when sub-optimal hygiene is present, bacteria from the hands of the infected person that got there from contact with its own feces (after going to the bathroom, for example) is passed to the next person. This happens a lot in the food business, and it's the mode of transmission of the much famous Salmonella.
