Opis:
Background. Despite the efforts and investments made for traceability and the guarantee of a fair and safe milk product, the informal sector threatens the safety of milk. In fact, during this circuit, the product does not undergo any treatment and therefore presents serious risks for the health of the consumer. In this context, studies have been carried out on samples of peddled milk and products derived from it. Objective. The purpose of this study is to evaluate the relevance of the informal circuit in Morocco's Doukkala region (El Jadida Province) by physicochemical and microbiological investigation of raw milk and its derivatives at various points of sale. Materials and method. 84 samples were taken between (23 for raw milk, 30 for the «Lben», and 31 for the «Raib») between January 1st, 2021 and October 30th, 2021. According to Moroccan rules, microbiological analyses revealed an extremely high non-compliance rate in most samples obtained at the level of outlets situated in the El Jadida region, with a non-compliance ratio of 65 percent for raw milk sold, 70 percent for the «Lben», and 40 percent for the «Raib». Results. Likewise, these analyses revealed that majority of the samples did not fulfill international criteria for the pH values of raw milk samples «Lben» and «Raib», which are respectively between 5.85 and 6.71; 4.14 and 4.43 and 4.5. Other characteristics, including lactose, proteins, fat, mineral salts, density, and additional water, have also yielded results. Conclusion. This has allowed us to analyze the major impact of the peddling circuit at the regional level, which is a risk factor for consumer health.

Background. Milk is a nutritious food for humans, but it is also an ideal growth medium for pathogenic bacteria such as Salmonella, Listeria monocytogenes or Campylobacter spp, which can cause food poisoning. Objective. For this reason, we evaluated the microbiological, physicochemical and hygienic quality of raw milk samples in 9 milk collection centres and cooperatives in the Beni-Mellal-Khenifr region before and after the implementation of the quality management system, hazard analysis and critical control points (HACCP). Materials and Method. The microbiological and physico-chemical quality of 184 raw milk samples in 9 milk collection centres and cooperatives in the Beni-Mellal-Khenifra region was evaluated before and after the implementation of the quality management, hazard analysis and critical control points (HACCP) system. Results. The physico-chemical results obtained after the implementation of HACCP revealed that 78% of the samples analysed were below the maximum limits authorised at international level. A pH between 6.6 ±0.11 and 6.8±0.02, an acidity of 15°D, the milk is stable according to the Ramsdell test which is negative at 0.9. The temperature remains within the acceptance range with an average of 6.62 ±0.45°C to 7.7 ±0.36°C and the fat content is between 33 and 45g/ml. We also noted an improvement in the microbiological quality of milk in 81% of collection centres and cooperatives. The level of contamination by total coliforms is from 2.5x104 to 11.5x104 CFU/ml lower than the Moroccan standard (NM 08.0. 100) of 1.5x104 CFU/ml to 20.3x104 CFU/ml, the total aerobic mesophilic flora and the psychrotrophs have an average of 2.5x105 germs/ml to 82x105 germs/ml lower than before improvement (12.5x105 germs/ml to 192x105 germs/ml). Conclusion. We can conclude that the work done leads to an improvement and satisfaction of the quality of raw milk compared to the standard after the implementation of HACCP.
