[Risk of Listeria infections in humans]

Area of Science:

• Veterinary Medicine
• Human Epidemiology
• Infectious Diseases

Context:

• Listeriosis is a serious infection caused by Listeria monocytogenes bacteria.
• Animal populations can act as reservoirs for Listeria monocytogenes.
• Human infections are often linked to contaminated food products, but zoonotic transmission is also a concern.

Purpose:

• To assess the risk of listeriosis transmission from infected animals to humans.
• To evaluate the effectiveness of serological and clinical examinations in detecting human exposure.
• To quantify the actual risk of infection in individuals with direct animal contact.

Summary:

• Serological and clinical examinations were conducted on individuals who had contact with animals diagnosed with listeriosis.
• The study found a low incidence of infection among the examined human population.
• Results indicate that the risk of contracting listeriosis through direct contact with infected animals is minimal.

Impact:

• Provides crucial data for public health risk assessment regarding zoonotic listeriosis.
• Informs veterinary and medical professionals about the actual risk of transmission.
• Helps in developing targeted prevention strategies and reassuring the public about animal-to-human transmission risks.
