“…For example, FAGBAMILA et al [11] in Nigeria reported that out of 900 egg samples analyzed using the disk diffusion test, 32 (3.6%) contained antibiotic residues and 18 eggs (2%) gave positive results with the Premi ®Test method. In Senegal, the presence of antibiotic residues was qualitatively confirmed in eggs at 12% [12].…”

The quality of agri-food products, in particular those of poultry origin, has now become an imperative. Because of the antibiotics used in poultry production, we are seeing the presence of antibiotic residues in products from poultry farming, especially eggs. Residues in eggs do not always comply with regulatory requirements, which can have harmful consequences for consumers such as: risk of allergies or risk of antibiotic resistance. This study was carried out with the aim of evaluating the presence of residues of veterinary antibiotics in eggs produced and marketed in the district of Bamako and surroundings. All samples were analyzed using the Premi ®Test which is a rapid detection kit for antibiotic residues in different materials. We collected 900 eggs from 10 farms and 10 markets in Bamako. Out of 900 eggs, 228 were tested. One hundred and eighty-nine (189) eggs tested negative for the presence of antibiotic residues, i.e. 82.9%; on the other hand, 39 were positive, i.e. 17.1%. This study clearly shows the presence of antibiotic residues in eggs from farms and various markets in Bamako and the surrounding area. This will allow us to continue our study at a later date to identify the types of antibiotic and to dose them.

Aims: The objective of this study is to estimate the health risk incurred by the Ivorian adult consumer as a result of exposure to AFB1 and the sum of aflatoxins (AFT) through the consumption of maize. Place and Duration of Study: During this study 375 samples of maize (grains, cobs, spathes) were taken from February 2016 to January 2017 and the analyzes were carried out at the Biotechnology Laboratory, Agriculture and Development of Biological Resources of the Félix HOUPHOUËT-BOIGNY University. Methodology: The detection of aflatoxins (AFB1, AFB2, AFG1, and AFG2) was performed by HPLC using the AOAC method. The risk analysis procedure was conducted according to the Codex Alimentarius risk analysis model. It consisted of a quantitative assessment. The quantitative estimation of the aflatoxin exposure was performed according to the deterministic approach. Results: The results indicate the presence of aflatoxins B1, B2, G1 and G2 in all forms of maize (grains, cobs, spathes) and in the five regions visited. The average concentrations of aflatoxin B1 (AFB1) and the sum of aflatoxins (AFT) ranged from 0.79 ± 0.04 µg/kg to 130.31 ± 22.56 µg/kg and from 2.63 ± 2.35 µg/kg to 169.13 ± 40.39 µg/kg, respectively. Subsequently, the Estimated Daily Intakes (EDI) by consumption of aflatoxin-contaminated maize vary according to the level of contamination. They range from 0.28±0.00 ng/kg body weight/day to 52.85±9.14 ng/kg body weight/day for AFB1 exposure. They ranged from 1.00±0.85 ng/kg body weight/day to 68.57± 16.28 ng/kg body weight/day for AFT exposure. Samples of maize grains and cobs from the Gbèkê, Poro and Hambol regions showed low daily doses below the reference values (2.028 ng/kg body weight/day and 4.056 ng/kg body weight/day). The opposite results are observed with samples (grains, ears and spathes) from Indenié-Djuablin and Gountougo. Conclusion: The results of the daily doses of aflatoxin exposure of these regions show a need for monitoring their production. Thus, the implementation of efficient technical itineraries throughout the maize distribution chain, both during production, post-harvest processing, and conservation will be able to guarantee a better sanitary quality of this agricultural food product.

“…They are composed of carbon atoms forming benzene rings (2 to 10) and hydrogen atoms [1]. Among these molecules, sixteen (16) have been prioritized by the United States Environmental Protection Agency (US-EPA) due to their abundance in the environment and/or their extensive use by industry. The fear caused by PAHs comes from the fact that they are contaminants resulting from combustion processes and some of these molecules are considered potentially carcinogenic, including Benzo (a) Pyrene [2].…”

“…The fear caused by PAHs comes from the fact that they are contaminants resulting from combustion processes and some of these molecules are considered potentially carcinogenic, including Benzo (a) Pyrene [2]. However, the World Health Organization (WHO) proposes to monitor mainly six (6) of the sixteen (16) PAH molecules that are considered as priorities because of their harmful effects on the environment and their high toxicity [3]. These are Benzo (a) Pyrene, Fluoranthene, Benzo (a) Fluoranthene, Dibenzo (ah) Anthracene, Benzo (k) Fluoranthene, Benzo (g,h,i) Perylene and Indeno (1,2,3-cd) Pyrene.…”

Aims: The objective of this study is to evaluate the exposure of consumers to polycyclic aromatic hydrocarbons (PAHs) and to estimate the health risk related to the consumption of braised fish from eight (8) communes of the District of Abidjan in order to contribute to the protection of these consumers. Study Design: This experimental study consisted in sampling fish cooked with charcoal embers in the collective catering circuit, followed by the determination of PAHs and the estimation of health risks. Place and Duration of Study: The braised fish samples were collected in the Autonomous District of Abidjan and analyses were performed at the Central Laboratory of Agrochemistry and Ecotoxicology between January and March 2015. Methodology: PAHs were extracted and purified on a Bond Eut C18 cartridge and then determined by High Performance Liquid Chromatography (HPLC) according to ISO 15753. Results: All the eight (8) PAH molecules investigated were found in varying concentrations and numbers in the braised fish depending on their origin. Concentrations range from 0.013 \(\mu\)g/kg to 1.246 \(\mu\)g/kg for individual molecules and from 0.670 \(\mu\)g/kg to 3.271 \(\mu\)g/kg for total PAHs (TPAHs) regardless of the municipality and PAH molecule. In addition, 0-25% of the samples are non-compliant with the standard for PAHs and 0-13% for TPAHs. Also, braised fish collected in the communes of Marcory and Plateau contain eight (8) molecules while variable numbers of molecules are found in those from other communes. Thus, seven (7) molecules were found in four communes (Abobo, Cocody, Koumassi, Port-Bouet) and six (6) molecules in two communes (Treichville, Yopougon). However, all hazard quotients (0.00000-0.00041) are less than 1 regardless of the municipality and PAH molecule. Conclusion: These results are essential to improve the safety of braised fish made available to consumers of differents communes of the District of Abidjan. These results recommend the consideration of other sources of PAH in the diet although the hazard quotients are less than 1 because PAH molecules have a cumulative power in the body.
