Study Notes
Food Safety and Nutrition
- Food safety is about handling, storing, and preparing food to prevent infection.
- Germs not only cause diseases but also destroy valuable nutrients in food.
- Unsafe food can cause infections or diseases such as diarrhea, meningitis, etc.
Indigenous Knowledge in Safe Food Production and Postharvest Handling
- Farmers' indigenous knowledge can be used to develop integrated pest management (IPM) techniques.
- Traditional storage structures are made of locally available materials to reduce post-harvest losses.
- Farmers use botanicals and wood ash to preserve food.
- Different forms of traditional storage structures are used to store grains like maize and sorghum.
Traditional Storage Structures
- Underground pit grain storage is common in dry lands of Ethiopia.
- Gombissa is a traditional above-the-ground cylindrical storage bin used to store maize cobs.
- The roof of Gombissa is thatched with dry grass or corrugated iron sheets.
Use of Botanicals and Wood Ash
- Botanicals are chemicals produced by plants that repel insects and deter feeding and oviposition.
- Wood ash has been used for centuries as a botanical pesticide against maize storage insect pests.
Storing Unshelled Maize
- Maize cobs that are completely covered by the husk are less infested than those whose tips are slightly exposed.
- Mixing with sand and dust, and mixing with small size grain are also used to protect stored grains from insect pests.
Food Safety Hazards and Health Risks
- There are four primary categories of food safety hazards: biological, chemical, physical, and allergenic.
- Biological hazards are characterized by the contamination of food by microorganisms.
- Chemical hazards are caused by the presence of harmful substances that can be found in food naturally or unintentionally added during processing.
- Physical hazards are foreign objects found in food products.
