Which pathogen is among the three that accounted for about 78% of illnesses at animal exhibits along with E. coli and Cryptosporidium?

• A. Salmonella
• B. Staphylococcus aureus
• C. Campylobacter
• D. Giardia lamblia

Answer: (A)

Exposure at animal exhibits often leads to illness from fecal-oral pathogens carried by many animals. In outbreaks linked to these settings, E. coli and Cryptosporidium are two well-known culprits, and the third major pathogen that appears frequently is Salmonella. Salmonella is common in livestock and poultry and can spread readily through direct contact with animals or contaminated surfaces. It has a relatively low infectious dose, so brief or low-level exposure can cause illness, which helps explain why it accounts for a large share of exhibit-associated cases alongside E. coli and Cryptosporidium. While other organisms like Giardia or Campylobacter can cause similar illnesses, the data for animal-exhibit outbreaks consistently highlight Salmonella as the third major contributor.
