coli outbreak, with no known restaurant our social event being in common with any cases. This suggests that a grocery store supplier most likely had a contaminated batch of either lettuce or alfalfa. This E. coli, was most likely transmitted by a food handler somewhere along the grocery supply chain. Produce suppliers should be targeted as the next probable source of the virus. Question 8A Finding controls for this study would

Ecoli Escherichia coli (E. coli) is notorious for its adverse effects on the human body. A bacterium that normally lives in the stomach, some strains of E. coli can cause illness such as diarrhea. The strains most harmful to human beings include E. coli O157:H7 (Mayo Clinic Staff, 2011). Food and water contaminated with these harmful strains of E. coli are usually the means by which the bacteria is transmitted; adults

Question 14 The main criteria that should be considered is the type of infection based on microbiological evidence. Additionally, it is important to determine whether or not there was onsite mishandling which may have led to E. coli being present on particular products. The scope of the outbreak would also be important, as it would show either a local outbreak, or a more widespread one that would indicate a larger producer. Question

"Elimination of these and other pathogens from the lower respiratory tract is made possible by an effective innate immune response, which is necessary yet potentially dangerous to the infected host." E. coli Outbreak: There have been numerous E.coli outbreaks over the years. Pakalniskiene, Falkenhorst, Lisby, and Madsen (2009) studied one of the larger single source outbreaks. On November 11th, 2006, there was an outbreak in Greater Copenhagen, Denmark. The director of

Instituting these measures showed that the company was vitally interested in not only maintaining the company's integrity, professionalism and reputation but also in ensuring that the problems never arose again. Other methods initiated by the company included a program that would test heat cleaning of apples that would kill the bacteria while not affecting the taste of the apples. The company also introduced a process of cleaning and decontamination called
