Residual levels of pesticides in filet green beans from Souss-Massa, Morocco.
Environ Sci Pollut Res Int
October 2024
A total of 30 samples of filet green beans (Phaseolus vulgaris) from various popular markets in the Souss-Massa region (Morocco) were analyzed during 2021 for the presence of pesticide residues. We performed a QuEChERS extraction (Quick, Easy, Cheap, Effective, Rugged, and Safe) combined with Liquid Chromatography-Mass Spectrometry (LC-MS/MS) and Gas Chromatography-Mass Spectrometry (GC-MS/MS). The method was validated in accordance with SANTE 11312/2021 guidelines.

- Alicyclobacillus bacteria are problematic in the beverage industry due to their ability to survive typical pasteurization methods, leading to quality issues related to odor and taste, while their health effects on humans are not clearly defined.
- An experimental study was conducted using cell cultures and rodent models to assess the safety of various strains of Alicyclobacillus, focusing on their impacts on intestinal cells and potential cytotoxicity.
- Results indicated that Alicyclobacillus spp. showed negligible cytotoxicity and minimal safety concerns, suggesting they are biocompatible in the tested models.
Background: , a Gram-positive bacterium, is a prominent foodborne pathogen that causes listeriosis and poses substantial health hazards worldwide. The continuing risk of listeriosis outbreaks underlies the importance of designing an effective prevention strategy and developing a robust immune response by reverse vaccinology approaches. This study aimed to provide a critical approach for developing a potent multiepitope vaccine against this foodborne disease.

Results showed that out of the total samples, Pb was detected in 39 date fruit samples (46.43%) in the range of 0.

- - The study focused on the probiotic strain 12-3, isolating it from Tibetan kefir grains to analyze its genomic features and potential therapeutic uses, including its safety applications as a probiotic.
- - Using advanced sequencing technologies, researchers verified the genome's completeness and identified 3,234 genes while assessing antibiotic resistance, genetic diversity, and food safety implications of the strain.
- - Findings highlighted significant genetic elements involved in the strain's defense mechanisms, suggesting that 12-3 could be engineered for enhanced probiotic functionality in future applications.
