Pesticides are a potential health hazard for users and consumers and are a major constraint to the export and commercialization of mangoes. The objective of this study was to evaluate phytosanitary practices in orchards and pesticide residue levels in four varieties of fresh and dried mangoes (Amelie, Brooks, Kents and Lippens) produced in four localities in Burkina Faso in order to determine their health impact on consumers. Surveys on pesticide use and monitoring of phytosanitary practices were carried out among 16 orchard owners in the localities of Bobo-Dioulasso, Orodara, Toussiana and Banfora, a high mango production area. Also, a total of 120 samples, including 60 samples of fresh mangoes and dried 60 samples of dried mango were collected. A multi-residue method was developed to detect pesticide levels in the collected samples by gas chromatography with a micro-electron capture detector. The study revealed the use of unauthorized pesticides, often specifically for other crops, and a monitoring trapping network in the orchards against insects. 34 chemical pesticides were detected in 120 samples of all mango varieties collected. Pesticide residues were detected in 72% of the samples, and of the positive samples, 48.52% contained concentrations above the maximum residue limit permissibility. Organochlorine pesticide residues were present in fresh mangoes (60.5%) and a total of fifteen active compounds were detected in dried mangoes. The very poor management and use of pesticides found in these orchards could pose a threat to the productivity of natural ecosystems and the health of producers, processors and consumers. Awareness raising and training of producers on the knowledge of the risks linked to the use of pesticides and good practices are necessary to preserve the health of all.展开更多

Overweight and obesity are the fifth most common risk factor for death worldwide, killing at least 2.8 million people each year. In view of the importance of the subject and the lack of sufficient data in our context, it seemed appropriate to us to carry out this preliminary work in Burkina Faso on a population of subjects followed in consultation with Nutrition and Dietetics. The general objective of our work, of a descriptive cross-sectional type, was to describe the epidemiological, clinical, biological and therapeutic aspects of obesity in a population of consultants, black Africans over a period of one year. The study concerned three (03) private care establishments (clinics) in the city of Ouagadougou in which a Nutrition and Dietetics consultation was available. This was a descriptive cross-sectional study which concerned 64 patients followed in nutrition and dietetics consultations <span>from January 2 to December 31, 2012. The material of the study is repr</span>esented by the analysis of the files of 64 patients followed in consultation of Nutrition and Dietetics in three (03) medical clinics. The most affected age groups were 30 to 40 years (19 cases) and 40 to 50 years (18 cases);53 women (82.8%) and 11 men (17.2%), <i>i.e.</i> a sex ratio of 4.82. Among our patients, 12 people were overweight (18.75%), 23 had moderate type I obesity (35.94%), 15 severe type III (23.44%) and 14 had type III obesity massive (21.87%). Android-like obesity was predominant in 53 people (82.81%). Among our patients 16 (25%) presented with dyslipidemia, 49 (76.56%) had eating disorders. The most common cloudy snacking was observed in 33 people (67.35%). In terms of evolution and therapy, 31 people (48.44%) followed the diet at term;the others had either abandoned or discontinued treatment, namely therapeutic changes in lifestyles. A total of 51.56% were lost to follow-up. The mean duration of follow-up was 2.7 months. In sum, obesity mostly affects young adults (30 to 40 years old) and females, with a predominance of type I o<span>besity (moderate). Android-type obesity was predominant in both sexe</span>s. Preventive actions are needed for citizens of Ouagadougou.展开更多
