Aflatoxins are frequent contaminants of maize especially in the face of climate change with deleterious health and socio-economic impacts. South Africa is ranked 9th maize exporter globally; hence, insights need to be gained in terms of the maize value chain in South Africa with respect to aflatoxin contamination to evaluate consumers' exposure. High-performance liquid chromatography (HPLC) technique was used in this study to quantify aflatoxins in South African commercial maize. One thousand and twenty-eight (1028) maize samples were collected across six distinct agro-climatic regions over five harvest seasons (2017 - 2021). A total of 205 samples (19.94 %) were found to be contaminated with aflatoxins, with mean total aflatoxin concentration of 64.17 ppb amongst the contaminated samples, which is above the SA regulatory limit of 20 ppb for animal consumption. The year 2018 recorded the highest mean total aflatoxin value while North-West agro-climatic region had the highest mean total aflatoxin value. Drastic reduction in average rainfall significantly influence aflatoxin contamination of South African maize.

The contamination of food and animal feeds with mycotoxions, particularly aflatoxin B1 (AFB1), poses significant risks to human health and causes economic losses. This study investigated bacteria from various fermented milk products to assess their ability to detoxify AFB1. A variety of household fermented kefir milk, kefir-like beverages, and kefir grains were collected from rural areas and subjected to microbiological analysis.

To assess the ameliorative effects of wireweed leaf supplement (WLS) and ascorbate on reproductive potentials and gonadal oxidative status of cocks fed aflatoxin B1 (AFB1) contaminated diets, a total of 250 sexually mature cocks were distributed into five treatment groups: 1 (Control/Basal diet), 2 (Basal + 1 mg/kg AFB1), 3 (Basal + 1 mg/kg AFB1 + 200 mg/kg Ascorbate), 4 (Basal + 1 mg/kg AFB1 + 2.50 g/kg WLS) and 5 (Basal + 1 mg/kg AFB1 + 5.00 g/kg WLS).

Aflatoxins (AFs) are secondary fungal metabolites that contaminate common food crops and are harmful to humans and animals. The ability to degrade or remove aflatoxins from common feed commodities will improve health standards and counter the economic drain inflicted by AF contamination. Bioremediation is a promising solution to AF contamination because of its low cost and few undesired environmental side-effects.

Background: Mycotoxins are considered one of the most important problems and threats that face poultry producers.
Aim: This study was conducted to investigate the pathological, hematological, and biochemical alterations in chickens fed on mycotoxins contamination ration.
Methods: 434 feed samples were collected from poultry farms operating in Babil Governorate/Iraq, where feed samples were collected over the course of 2023, and these samples were tested by direct competitive enzyme-linked immunosorbent assay to determine the level of mycotoxins.
