CAIRO: In preparation for the holy month of Ramadan is people are stocking up on beans, lentils and other types of grains usually used to break the fast or for sohur.
However, large quantities of these foodstuffs are likely to breed grain insects and parasites detrimental to general health, a researcher warns.
Dr Shadia Abdel Aziz, of the National Research Centre, said that parasites and insects thrive in stored brown and white beans, nuts, dried dates and plant seeds.
Losses in the world grain production attributed to such parasites and insects have been estimated at 10 percent a year. They account for the loss of between 40 and 80 million tons of grain, enough to feed 350 million people.
The losses are higher in hot countries where the high temperature and humidity provide an ideal environment for the spread of such parasites and insects, Abdel Aziz explained.
“Some spread like wild fire, the researcher said. “Take, for example, the flour beetles. A couple of these beetles can produce a million insects in just 150 days.
If the correct storage procedures are followed though, outbreaks can be avoided, Abdel Aziz stated.
“Some people store large quantities of these grains at home, which can lead to health problems. Humidity, in particular, is one of the major grain pollutants. Once it hits rice and flour, it breeds fungal poisons that can cause cancer, she explained.
“To store these kinds of foodstuffs, we need moisture-free containers. These are not often available at home, she added. “It’s worthwhile, therefore, to follow certain instructions when buying grains in big quantities.
“First examine the grains carefully to make sure they are free of insects or any infections. Then place the quantity in the deep freeze for three days to inhibit the hatch.
The researcher also advised that the grains should be stored in carefully-sealed jars or durable nylon bags. The places used for storage should be regularly cleaned with a vacuum cleaner, soap and water.
Holes in the kitchen and dining rooms should be looked out for and blocked when found. Grains should be kept in the fridge in sealed containers and rice should be stored mixed with rough salt.
Insect deterrent spices like cinnamon and “habit el baraka (black seed) sprinkled on the shelves could help too.
