Garri (Cassava Flour) is made from Raw Cassava. Cassava is a tuber crop, which contains a very high level of starch, and is processed in many ways to get an edible end-product.

Below is a step by step process on how to make garri:

  • After you have gotten your cassava tuber from the farm or market, Peel off the skin.
  • The next step is to Wash the peeled tubers. Try to wash the peeled tuber thoroughly in clean water and remove all forms of dirty things including sand.
  • Cut the tubers into pieces by pieces.  Smaller sizes increase the speed. Then you ground in a grounding machine.
  • After the grinding, the cassava powder will still be watery and need to be packed in long bags and taken to be drilled to promote ultimate dryness in a jack for 2-3 days.
  • When it’s dried, use a wide sieve to sieve off the fine cassava powder from other particles.
  • The next step is to fry using a wide frying pan, fry the powder in reasonable portions until it becomes dry and brittle.
  • Sundry your garri in a clean environment to reduce the effect of bacteria that may lead to spoilage.


The last and final step is to store your garri in a cool and dry place and where it will be ready for consumption.

Health Effects of Garri on the body

The main health effect of garri consumption is related to the cyanide content of cassava from which garri is produced.
Garri is made from cassava which is known to contain hydrocyanic acid. Although the processing process of garri significantly reduces its Cyanide content,  it has been linked to eye defects which is the main disadvantage of garri consumption.

According to Dr. Ben Ajayi an Ophthalmologist, “Cyanide is slightly similar in structure to Vitamin B12 (cyanocobalamin).
So it competes with Vitamin B12 replacing it and adversely affecting rapidly growing tissues or tissues that are regularly being renewed such as the skin, peripheral nerves and the nerve of the eye (optic nerve). It is the involvement of optic nerve which can lead to eye defects and blindness. Garri also leads to intestinal issues and worsening of ulcers. Proper and thorough processing of the garri should reduce the concentration of the acid.

A study which evaluated the cyanide concentration of six garri samples  in Nigeria Published in the World Journal of Nutrition and Health revealed that,  four of the samples  analysed contained cyanide in the range of 2.10-9.10 mg HCN/kg  which falls  well below the permissible limit while the remaining two samples had higher residual cyanide content of 11.78 and 15.30mgHCN/kg which is above the permissible limit of 10.0mgHCN/kg  set by the World Health Organization WHO.

It is also important to note that, garri that is not properly processed or stored can also constitute a major threat to public health.

A study conducted by The Makerere University Medical school and Published in the African Journal of health sciences which analyzed garri from different states  revealed that garri contains eight bacteria genera namely (Bacillus, Staphylococcus, Streptococcus, Pseudomonas, Clostridium, Salmonella Klebsiella and Coliforms groups) genera and six fungi genera (Aspergillus, Penicillium, Rhizopus, Botrytis, Fusarium, and Cladosporium) In addition to  Aflatoxins B1, B2, G1 and G2.
