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.

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

イメージ
We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
