Proverb: “From farm to fork, keep food safe.”
Microorganisms are everywhere. You may not see, taste, or smell them, but they hide on your body, in the air, on kitchen counters and utensils, and in food. The main microorganisms are viruses, parasites, fungi and bacteria. they can contaminate the food and cause food spoilage or foodborne infection . Of all the microorganisms, bacteria are the greatest threat to food safety. Bacteria are single-celled, living organisms that can grow quickly at favourable temperatures. Some bacteria are useful. We use them to make foods like cheese, buttermilk, sauerkraut, pickles, beer and yoghurt. Other bacteria are infectious disease-causing agents called pathogens that use the nutrients found in potentially hazardous foods to multiply.
Food preservation is the process to handle and treat food in order to control its spoilage by stopping the attack and growth of foodborne diseases causing microbes; avoiding oxidation of fats (rancidity) and maintaining the nutritional value, texture and flavour of the food. One of the main challenges facing Africa today is ensuring food security, as the countries demand more food than before with the increase in population. Simple, low-cost, traditional food processing techniques are also the bedrock of small-scale food processing enterprises that are crucial to rural development in Africa. Traditional/indigenous foods also provide inexpensive, safe, nutritious foods throughout the whole year thus boosting overall food security. This lecture considers the Indigenous methods of food preservation and food security in Africa.
