Final answer:
Emerging foodborne pathogens like E. coli O157:H7 have caused significant outbreaks, exemplified by the 2006 spinach contamination in the U.S., highlighting the need for strict food safety practices.
Step-by-step explanation:
Two emerging foodborne disease pathogens include Campylobacter jejune and Escherichia coli O157:H7. Among these, E. coli O157:H7 has been involved in significant outbreaks. One notable outbreak was linked to contaminated spinach in the United States in 2006, causing 199 illnesses and three deaths. To prevent such outbreaks, it is essential to maintain strict hygiene and proper cooking methods, especially for foods likely to carry these pathogens.
Foodborne illness often presents with symptoms such as vomiting and diarrhea, with the incubation period and infectious dose varying widely depending on the causative agent. The majority of cases are sporadic; however, when multiple cases arise from a common source, it is termed an outbreak.
