Screening For Diseases

 SCREENING FOR DISEASES Please answer the questions Knowing the pathogen and its characteristics (including modes of transmission)      where do you think was the most likely point of contamination in the production of the sprouts? In inspecting the alfalfa fields and harvesting process, what possible points of contamination should be considered? What interventions/control measures would you suggest? Why?In preparing a report of this investigation, what possible strengths and limitations should be discussed? Length: Should be at least 4 pages (1000 words) in length, APA format***For the SLP****While the assignment may be based on a real case, the questions can refer to any outbreak that involved sprouts and E. coli 0157:H7. Knowing the specific pathogen (its characteristics, transmission) and the specific food, how could the contamination have occurred? You are asked to think about a possible point of contamination and about measures of control.
