摘要：Pathogens are disease-causing
microorganisms that include
bacteria, fungi, parasites, and
viruses. Pathogens can cause illness
through contaminated food, contaminated
water, or person-to-person
contact. Most foodborne illnesses
typically have a rapid onset and are
self-limiting. Common symptoms
are gastrointestinal problems and
vomiting. Foodborne illnesses range
from mild to severe; some of the
more severe cases can result in premature
death.
