What is the primary concern of E. Coli strains associated with food contamination?

The primary concern of E. Coli strains associated with food contamination is that they can cause severe diseases. Certain strains of E. Coli, particularly O157:H7, are pathogenic and can lead to serious health issues such as severe stomach cramps, diarrhea (which may be bloody), and in some cases, more severe complications like hemolytic uremic syndrome (HUS), which can result in kidney failure. Understanding the pathogenic potential of these strains is critical for food safety, as proper handling and cooking of food are essential to prevent E. Coli infections.

The other choices do not accurately capture the risks associated with pathogenic E. Coli. Some strains can be harmless or even beneficial, but the focus here is on those associated with foodborne illness. While not all E. Coli strains are fatal, the potential for serious illness makes awareness and prevention a priority in food safety practices.
