One of critical public health concerns in many developing countries today is water quality and the risks associated with waterborne diseases. Many research works that have studied about factors contributing to water pollution have not considered the perception on drinking water quality and health risk in the rural area of the department of Tiassalé. This study therefore focuses on evaluating the level of perception of households living in the rural area of Tiassalé. The study data were collected through interviews from a total of 600 respondents with structured questionnaire. The majority of the respondents (78.2%) used water from hand dug wells for drinking purpose. According to 77.7 % of respondents, water from the wells was safe for drinking. Around 9.3% had a degree of knowledge about the sources of well water contamination. Majority of the respondents (87.3 %) did not treat their water. About 80% of residents mentioned that they had not experienced any negative effects from drinking the well water. Variables associated with perception of drinking water quality included educational status, use of at least one method

Shortage and high cost of conventional proteins (meat and fish) in our developing countries means that we have to find new sources of protein. The shrimp (Penaeus notialis), produced in large quantities worldwide and particularly in Côte d'Ivoire, is a track to be exploited. This study was conducted to assess the nutritional quality of this unconventional protein from freshwater. Overall chemical characterization in grams per 100g / dry matter of the powder of this animal was carried out by standard methods (AOAC).The macromolecule content (carbohydrate, fat and protein) gave 44.4%, 7.86% and 34.21% respectively. Nutritional parameters that are the total dry matter ingested (MSTI), the total protein ingested (PTI) in grams/ day and the food efficiency coefficient (CEA), the protein efficiency coefficient (CEP) and the weight of these animals were evaluated on the basis of animal experimentation carried out in the animal physiology laboratory. Second consumption experiment gave an MSTI of 8.8 g / day respectively with a PTI of 0.82 on the one hand. On the other hand, a CEA of 0.20 and a CEP of 1.91 for the shrimp diet.All these values show no significant difference with that of the control diet (Casein) and the fish diet. The growth determined by the weight variation of rats fed the shrimp diet remains greater compared to that of the control and fish diets.This study showed that proteins from the shrimp diet (Penaeus notialis) may well be a nutritional alternative alongside conventional meat. Additional studies may be conducted to more specifically determine the micronutrient composition of this animal protein.

Background: Many medicinal plants including Spondias mombin L are used in traditional medicine for treatment of many pathology. It is therefore used for rational for remedies derived from medicinal plants. Aim: As part of concerning traditional medecine drugs, a toxicology study was conducted on the stem bark of Spondias mombin L., remedy used to treating of diarrhea. Materials and method: Total aqueous extract of the stem bark of this plant was orally administered at one dose of 2000 and 5000 mg/kg body weight to two (2) batches of five (5) female rats during fourteen (14) days. Five (5) female rats control group consisting received distilled water. All the animals were sacrificed after treatment, their blood and nutritional organs such as (liver and kidneys) were removed. Results: This study showed no death was observed between the animals, however clinical signs were notified through the observation time. Indeed, the LD50 is therefore greater than 5000 mg/kg of body weight. In addition, hematological parameters analysis shows a significant increase of erythrocyte and leucocyte cells but not significant for thrombocyte cells. Therefore, it was observed, the weight of liver and kidneys significant increase. Conclusion: Stem bark of Spondias mombin L is a power immunostimulator which could justify is using of traditional medicine traitment for pathology.
