Study on toxigenic mycoflora and potential mitigation effect of Christmas Melon (Laganaria Breviflorus) extract in unpolished rice sold in Abeokuta Ogun state of Nigeria was carried out. Unpolished rice gotten from markets in Abeokuta were aseptically transported to the laboratory, serial dilution to reduce the fungal load was carried out and were plated on Potato Dextrose Agar (PDA) and Methyl Red Dessicated Coconut Agar (MRDCA) respectively. Microscopy, macroscopy, toxigenicity test and inhibition studies with the peeled and unpeeled fruit of Laganaria breviflorus fermented for seven days was carried out. Results reveal the predominance of Aspergillus as the major genera, specifically, A. niger, A.flavus, A. parasiticus, A. fumigatus, A. terreus, A. nidulans. Other fungi genera isolated include Penicillium, F`usarium, Mucor, Alternaria and Rhizopus . Of the 11 fungi genera isolated, 9 were toxigenic of which the zones of inhibition of unpeeled whole fruit extract of Laganaria breviflorus range from (3 - 28mm) where A. nidulans shows the highest susceptibility to the whole fruit extract of Laganaria breviflorus while the zone of inhibition of peeled fruit extract of Laganaria breviflorus ranges from (3 - 22mm) where A. parasiticus, Fusarium specie and P.chrysogenum showed the highest susceptibility . As the day progresses the zone of inhibition becomes wider. Unpeeled LB extract exhibited more zones of inhibition than the peeled LB extract. Laganaria breviflorus fruit extracts in the study demonstrates a potential in reducing toxigenic fungi, consequently a means to reducing mycotoxins in staple foods in Nigeria.

Drying is the process of removing of the water that has destroying effect in food products by evaporation and. Research project on the basis of direct sun drying and solar greenhouse. Basic operations research in food engineering, food chemistry, food quality control and toxicology has been established over such a broad spectrum. Subjects of investigation were in accordance with all of the values of dry matter basis. The study of dry matter and water activity values of each product (aw), direct sun drying, drying in the greenhouse. It was determined comparing nutrients of samples those were applied directly to the greenhouse and drying in the sun. Sampling patterns of research were explained as follow; tomatoes drying in the sun (external environment), and greenhouse, bell peppers in the greenhouse and drying in the sun, soaked raisins (sultanas) and not-soaked (raisin), sun-dried, sun-dried fig products directly. Nutrients of the samples such as; lycopene, thiamine (B1), riboflavin (B2), retinol (A), Pyridoxine (B6), ascorbic acid (C), folic acid, magnesium (Mg), potassium (K), sodium (Na), phosphorus (P), zinc (Zn), iron (Fe), copper (Cu) were quantitatively determined. The red pepper products, dried figs and dried grapes mycotoxin amounts were in safe levels, which had not created any hazard and risk for health. Red pepper and dried figs, total aflatoxins, (B1, B2, G1, G2), ochratoxin A (OTA) levels in raisin in the European Union is set well below the limits in terms of human health hazard and the risk factor has been identified.

Thirteen different mostly consumed cheese samples were obtained from different provinces in Turkey and were investigated in terms of contents of ergosterol, patulin and Ochratoxin A (OTA). Ergosterol, patulin and OTA analyses were carried out by using the apparatus of high-performance liquid chromatography (HPLC). Ergosterol contents of samples ranged from 30.27±0.69 to 144.76±9.41 mg/kg. The values of OTA in the samples were ranged from 6.96±0.05 to 41±0.2 µg/kg. Ergosterol was significantly correlated with OTA (r = 0.99, R2 = 0.98). According to this high correlation, ergosterol might be used as a more readily measurable indicator of potential OTA production. No patulin was detected in all samples. Absence of patulin on cheese samples may be explained with unsuitable media for patulin producing.

The aim of this paper was to systematically reviewing the selected feed factors. A worldwide food demand, including animal-derived food is highly predictable to increase at 60% by 2050, particularly in developing countries. By 2030, an annual meat consumption is also estimated to grow from 25.5 to 37 kg per person. In some parts of the world; however, such a growing demand isn’t currently matching with a comparable growth in the local production. For example, by 2050, around 40% of an animal-sourced food could be imported by African countries. Although such insufficiency of an animal-sourced food is generally due to that of the farm-animals’ low productivity, this is specifically believed to be because of the poor quality and inadequacy of the feeds. Both anti-nutritional factors (ANFs) and mycotoxins are the main factors that can contribute to the low quality and less efficiency of the feeds. Although some have beneficial effects, at their low concentrations, anti-nutrients are generally accountable for the harmful effects on the nutrient absorption. For example, up to 50, 23 and 10% of proteins and amino acid digestibility, in non-ruminant animals are reduced by the presence of trypsin inhibitors (TI), tannins and phytates, respectively. Feeds that are toxic for the mono-gastric animals may not be toxic to the ruminants. Soaking/roasting followed by pressure cooking is one of the best treating mechanisms to reduce those of the harmful effects of ANFs. Supplementation of the feeds with typical microbial enzymes, particularly when they are in a combined state enables also to reduce the negative effects of ANFs. A quarter of the world’s crops are being contaminated by the molds and fungi, and hence aflatoxin is an inevitable contaminant. Consequently, when animals eat these contaminated feeds, with aflatoxins the milk, eggs and meat could have the safety concerns to the human consumers. Due to that of some weak regulatory standards, the South-East Asian and sub-Saharan Africa (SSA) countries remain at a high risk of aflatoxin contaminations. In addition to that of the carrying-over impacts of aflatoxins, ANFs and mycotoxins are the main factors that are reducing the feed quality and efficiency, in animal production.
