For years, the residents of a small Mexican town complained about the filth from a nearby hog farm, where millions of pigs are raised each year
In 2009, the majority of residents in this town became sick with "swine flu," caused by the H1N1 influenza virus. This virus infects people but is apparently genetically similar to a virus that infects hogs. The virus has since gone on to infect (and, in some cases, kill) people in Mexico City, and has quickly spread around the entire planet. The "swine flu" has been declared a global pandemic.
Based on this scenario and your knowledge of genetics, what is a potential technique that could be used to prevent this disease?
A) Encourage people not to consume pig products. B) Make recombinant viral and human DNA.
C) Genetically engineer flu-resistant pigs. D) Develop a technique for STRs in swine.

There were numerous cases throughout the United States of patients having bloody diarrhea all within a week of each other, many of which were hospitalized with severe cases Although the people spanned from California to New York, they all had attended a high school graduation party. Epidemiologists determined the common food factor was cheese curds homemade by a farmer. The home where the cheese curds were made was searched, and the cheese curds and milk used to produce them were taken to the local government lab. Among other microbes, Campylobacter jejuni was isolated from many of the cheese curds as well as the farmer's bulk tank milk. What should be done for those infected? What can be done to prevent this from happening again?
