Food Safety Certification Practice Test

Rodents carry microorganisms that can cause diseases such as:

1. Influenza, pneumonia, and chickenpox

2. Salmonellosis, plague, and marine typhus

3. Diabetes, hypertension, and asthma

4. Hepatitis A, E. coli, and tuberculosis

The correct answer is: Salmonellosis, plague, and marine typhus

Rodents are known vectors for various diseases due to their ability to harbor and transmit microorganisms. The selection that identifies diseases like Salmonellosis, plague, and marine typhus aligns accurately with the types of illnesses associated with rodent populations. Salmonellosis is caused by Salmonella bacteria, which can be transmitted through contact with rodent droppings or contaminated food and water. The plague, historically significant, is primarily transmitted by fleas that have fed on infected rodents, showcasing the role of rodents as a host in the disease's transmission cycle. Marine typhus, also known as epidemic typhus, can occur in certain environments that include rodent interactions, emphasizing their involvement in disease spread. In contrast, other choices mention diseases that do not typically associate with rodent transmission, such as influenza and chickenpox, which are viral infections primarily spread through human-to-human contact. Diabetes, hypertension, and asthma are chronic conditions not spread by microorganisms and therefore are unrelated to rodent transmission. Lastly, while some bacteria like E. coli are related to foodborne illnesses, hepatitis A is primarily linked to fecal contamination from humans, not rodents. The choice emphasizing Salmonellosis, plague, and marine typhus provides a proper understanding of the
