Which pathogen is designated as EHEC/STEC in the raw milk pathogen list?

Explanation:
EHEC/STEC refers to Shiga toxin–producing strains of Escherichia coli. The most well-known member in this group is E. coli O157:H7, which is singled out in raw milk pathogen lists because it can cause severe illness such as hemorrhagic colitis and hemolytic uremic syndrome. Among the options, only E. coli O157:H7 fits the EHEC/STEC designation, while Campylobacter, Salmonella, and Cryptosporidium are important raw-milk pathogens but are not classified as EHEC/STEC.
