Study Notes

Course Overview

Aim: Educate on illnesses related to the consumption of contaminated foods.
Structure: 2 theoretical hours and 1 practical hour.

Unit I: Foundations of Food-borne Diseases

Definitions:
- Food-borne infection: Illnesses caused by consuming pathogens.
- Food intoxication: Illness caused by toxins produced by bacteria.
- Toxi-infection: Combination of infection and intoxication.
Topics Covered:
- Classification and epidemiology of food-borne diseases.
- Disease burden and economic impact of these illnesses.
- Identification of reservoirs for food-borne pathogens and their transmission modes.
- Pathogen vehicles: How pathogens spread through food sources.
- Prevention and control measures for food-borne diseases.
- Outbreak investigation: Steps in managing food poisoning cases.

Unit II: Bacterial Food-borne Infections

Focused Pathogens:
- Common bacterial culprits: Salmonella, Campylobacter, Clostridium, Staphylococcus, Listeria monocytogenes, Vibrio parahaemolyticus, E. coli, Bacillus cereus, Shigella, and Yersinia enterocolitica.
Topics Covered:
- Epidemiology and economic implications of infections.
- Diagnosis and management techniques for bacterial infections.
- Types of bacterial toxins: Their characteristics and health effects.

Unit III: Viral and Parasitic Food-borne Pathogens

Key Viral Pathogens:
- Hepatitis viruses, Entero-viruses, Noroviruses, Rotaviruses.
Additional Focus:
- Parasitic and rickettsial infections related to food.
Emphasis on epidemiology, economic aspects, diagnosis, and management of these viral and parasitic infections.

Unit IV: Toxins and Chemical Hazards in Foods

Illness caused by various contaminants:
- Food additives, seafood toxins, mycotoxins, biocides, plant-origin toxins, heavy metals, veterinary drugs, and hormones.
Anti-microbial resistance (AMR):
- Definition and significance in food-borne pathogens.
- Current status and influencing factors of AMR.
- Mechanisms of resistance, modes of transmission, and strategies for control and mitigation.

Description

This quiz explores the critical concepts related to food-borne infections and intoxications as outlined in the VPE 506 course. It covers definitions, classifications, epidemiology, and prevention measures for food-borne diseases. Test your understanding of the risks associated with contaminated food and the economics behind these health issues.
