  1. Toxicogenic Fungi, Aflatoxins, and Antimicrobial Activities Associated with Some Spices and Herbs from Three Selected Markets in Ho Municipality, Ghana

    • Sat, 06/25/2022 - 04:00
    • International Journal of Food Science
    • Spices and herbs are widely used food ingredients that enhance most organoleptic features of prepared foods. They are also used for medicinal and preservative purposes. Spices and herbs are potential carriers of bacteria, yeasts, and molds due to the nature of cultivation, harvest methods, storage conditions, packaging procedures, distribution, sale, and general handling.

  2. Growth and Aflatoxin B1 biosynthesis rate of model Aspergillus flavus NRRL 3357 exposed to selected infrared wavelengths

    • Sat, 06/25/2022 - 04:00
    • Food Control
    • Aflatoxin B1 (AFB1) is a highly toxic substance produced mainly by Aspergillus spp., which are known to contaminate a wide variety of foods and feeds. The objective of this study was to understand the growth and AFB1 production rate of Aspergillus flavus NRRL 3357 and investigate the impact of different infrared (IR) heat intensities on the growth and aflatoxin-producing potential of A.

  3. Effects of Turmeric Powder on Aflatoxin M1 and Aflatoxicol Excretion in Milk from Dairy Cows Exposed to Aflatoxin B1 at the EU Maximum Tolerable Levels

    • Fri, 06/24/2022 - 04:00
    • Toxins
    • Due to the climatic change, an increase in aflatoxin B1 (AFB1) maize contamination has been reported in Europe. As an alternative to mineral binders, natural phytogenic compounds are increasingly used to counteract the negative effects of AFB1 in farm animals. In cows, even low dietary AFB1 concentrations may result in the milk excretion of the genotoxic carcinogen metabolite aflatoxin M1 (AFM1).

    • Aflatoxin B1 is an important toxic food contaminant and there is very little information available about its exposure and effects on the health of the Pakistani population. Therefore, children (n = 238) aged 1–11 years were recruited in this study to estimate the levels of aflatoxin B1-lysine adduct and to measure its adverse effects on growth. Blood samples were analyzed to detect AFB1-lysine adducts through high-performance liquid chromatography.
