Question

question 4 of 5
what has helped to contribute to the spread of e. coli 0157:h7 in america?
a. the reduction in the value of minimum - wage salaries
b. the ease and inexpensive nature of airline travel
c. the high consumption of fast food overseas
d. the unsanitary conditions in cattle feedlots

Explanation:

E. coli 0157:H7 can be present in cattle. Unsanitary conditions in cattle feedlots can lead to contamination of meat (and potentially other products if cross - contamination occurs). Minimum - wage salaries (A) are not related to E. coli spread. Airline travel (B) is more about human - to - human spread of some diseases (not directly E. coli 0157:H7 in this context). High fast - food consumption overseas (C) is not the main contributor to its spread in America as the bacteria's source in America is more related to local livestock conditions.

Answer:

D. The unsanitary conditions in cattle feedlots
