Using the South University Online Library or the Internet, conduct a research to gain additional insight into the causes of food poisoning.
Based on your research, answer the following questions:

• What are the different types of screening or diagnostic tests available to study salmonella? What the advantages and drawbacks of each of the tests?
• If you were asked to employ the use of screening or diagnostic tests to study the transmission of salmonella, which screening or diagnostic tests would you recommend? Why?
• For each test, which of the following principles would influence the study outcome and results:
◦ Bias
◦ Confounding
◦ Values of sensitivity on epidemiological study validity
◦ Values of specificity on epidemiological study validity

• How will each principle influence the results of your epidemiological study based upon the type of screening or diagnostic tool?
• Which screening or diagnostic tool would you recommend as the most effective in the epidemiological study of salmonella transmission? Why?
