Fresh fruits and vegetables are often consumed raw or with minimal processing, making them highly vulnerable to food safety hazards. These hazards may be introduced at any stage of the supply chain and, if not properly controlled, can pose serious risks to consumer health and business integrity.

This module introduces learners to the three main categories of food safety hazards relevant to fresh produce: biological (or microbial), chemical, and physical. Through real-world examples and industry-aligned guidance, learners will understand how to recognize, assess, and prevent these risks to maintain safe, marketable products.

This module is structured into three core subsections:

1. Biological / Microbial Contamination

2. Chemical Hazards

3. Physical Hazards

Key Lesson Concepts:

• Understand the three primary types of food safety hazards: biological, chemical, and physical

• Identify common pathogens in fresh produce (e.g., E. coli, Listeria, Salmonella, norovirus) and how they are introduced via water, soil, animals, or workers

• Recognize conditions that allow microbial growth and survival on fresh produce

• Learn about chemical hazards such as pesticide residues, heavy metals, cleaning agents, and allergens

• Understand how improper application, runoff, or residue from prior land use can introduce chemical contamination
