Research Publications (Food Safety)

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  11. Pesticide residues in tomato crops in Western Algeria

    • Fri, 07/16/2021 - 14:06
    • Food Additives & Contaminants: Part B
    • This study aimed to evaluate levels of pesticide residues commonly used on tomato crops in Western Algeria. It showed a significant use of pesticides, especially insecticides (47%) and fungicides (41%) among listed pesticides in crop fields. A total of 30 tomato samples were analysed using multi-residue analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) after QuEChERS extraction.

    • Food Additives & Contaminants: Part B
    • This study reports a surveillance of multi-pesticide residues of fruits and vegetables sold in the local markets carried out in 2018–2019 in Botswana to access consumer safety. A validated method for analysis of 232 pesticide residues in fruits and vegetables was applied, based on QuEChERS-GC-MS/MS methodology. A total of 83 fruit and vegetable sold in different markets were bought from three different areas of the southern region .

    • Fri, 06/05/2020 - 14:04
    • Food Additives & Contaminants: Part B
    • An LC-MS/MS multi-residue method was validated for the determination of 59 pesticide residue levels in a chicken egg by using QuEChERS extraction method. The validation parameters used were taken from the SANTE/11813/2017 guideline. The calibration curves for each target pesticide had a good linearity in a range of 1.0 or 2.5 to 100.0 µg kg−1 (r2 ≥ 0.995). Ten per cent of the total pesticides had LOQ values less than 5.0 µg kg−1 or LOQ values from 5.0 to 10.0 µg kg−1.

    • Food Additives & Contaminants: Part B
    • The detection of pesticide residues in leafy vegetables has been a relevant concern in Chile over the last years. There is also a priority at the national level to propose a methodology to assess health risks. The aim of this study was to evaluate the presence of pesticide residues in ready-to-eat leafy vegetables in order to evaluate different models for health risk assessment. The models considered data of the World Health Organization (WHO) and the Ministry of Health of Chile (MINSAL).
