ABSTRACT

 

This study was supposed to be limited in area of capital region of Yaoundé to assess hazard of Aflatoxin B1 particular in dry maize and maize floor, food based in home cooked process. To achieve this work 20 samples were collectedin five markets in the area of Yaoundé: four samples per market:Mokolo, Huitième, Essos, Mvogbi, and Mfoundi.the 20 samples were analysed in the IMPM laboratories by ELISA method but the concentrations results were between 0.5>1>LOD =1ppb for 19 samples only one sample =20ppb.

 

Due to the fact that the datas were unusual, to establish a deterministic approach, we used the following datas of (Ediage and al., 2014 in A Comprehensive Study To Explore

 

Differences in Mycotoxin Patterns from Agro-ecological Regions through Maize, Peanut, and Cassava Products: A Case Study, Cameroon).The datas were analysed with software @RISK version 6and result’s comparation with standard and literatures reviews. We have considerate only the datas of maize with an assumption of three agro-ecological areas HFM, HFB and WH with exposure of (371; 213; 142 ng/kgBW/day). The level of population exposed to risk of intoxication by Aflatoxin B1fluctuate from 90% to 97% with deterministic approach.

 

Results of assessment revealed the high exposure and necessity to reduce aflatoxin intoxication, the best approach after a proposal of many alternatives is an integrated method.

situation of rice production in Cameroon (Ernest)

Japan-Cameroon cooperation project for the development of irrigated and rainfed rice (PRODERIP) Only 2 years after the creation in 2011 of this project piloted by the Ministry of Agriculture, 78 tons of rainfed rice seeds have been produced and are available for the 6000 producers already trained in this new way of growing rice in the country. With a budget of 1.5 billion CFA francs, this project, which benefits from the technical support of the Japanese Development Agency (JICA), has seen its 3-year implementation period extended to 5 years, due to the encouraging results already obtained, according to sources. The objective of this extension, according to Proderip, is to reach the milestone of 9,000 producers trained in the cultivation of rainfed rice, which has the particularity of growing on dry land and not exclusively in irrigated areas as is the case with traditional seed varieties. In addition, Proderip experts point out, rainfed rice, which currently produces around 48,000 ton...

UNPAD conference(Saito)

イメージ
  December 17 th  and 18 th  I and some laboratory member participated UNPAD conference. This conference is held two days. 1 st  day I listen 4 presentation from Prof Ph.D and Dr. They talked related to climate change. The next program was presentation by student. They talked their thesis. There were a lot of topic and I feel it is like Graduation thesis conference(In yamagata University B4 student make presentation for B2, B3 and Prof). I saw many research and I was interested in it. But some presentations I could not understand. So, I feel I should study terminology which used in facility of agriculture. The 2 nd  day I listen 3 presentation from Ph.D related their study. I study a lot of things from two days. And this two day was very interesting for me. Finally, there are closing. While this time, They give Sagae  an an award as Best Presenter. Congratulations! 　12 月 17 日と 18 日に研究室メンバーと UMPAD の会議に出席しました。この会議は 2 日間開催され、初日は 4 人の先生方から気候変動に関するプレゼンテーションがありまし...
