Without adequate refrigeration everyday staples – milk, eggs, dairy products, meats, fish and vegetables- easily spoil, and food safety is compromised.
Safe food supply is a basic ingredient of human health. Food poisoning -e.g. salmonella, clostridium, and staph infection- can have severe, long term, and sometimes fatal consequences, especially for the most vulnerable segment of the population, the young and the elderly. Adequate refrigeration improves the variety of foods available on a daily basis, which results in better nutritional balance, and greater public health.
The spoilage of food also has serious economic consequences, which are greatly magnified in a poor countries where feeding the population remains a national challenge.
In some areas without electricity or with poor electrical supply kerosene refrigerators are used to preserve food.
In the long term, solar/multi source powered refrigeration, provided that it can be made available at affordable prices, will have far-reaching benefits in domestic and small commercial refrigeration applications
