Aflatoxins (AFTs) are group of secondary metabolites produced by filamentous fungi such as Aspergillus flavus, A. parasiticus, A. nomius, and Emericella nidulans. AFTs contaminate foods, feeds, other raw ingredients used to produce them and that pose a significant threat to human health. These toxins designated as aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1), and aflatoxin G2 (AFG2), aflatoxin M1 (AFM1) and aflatoxin M2 (AFM2) are hydroxylated metabolites form of AFB1 and AFB2 are known as difuranocoumarin compounds. Naturally, these AFs have carcinogenic, teratogenic and mutagenic effects and caused several metabolic disorders such as aflatoxicosis in domestic animals and humans worldwide. For the increasing in cancer incidences these risk factors are liable. AFB1 is 1000 times more potent hepatocarcinogen found in food then benzo (α) pyrene carcinogen. This chapter offers contamination sources, effects and their controlling approaches to confirm the food safety.

Background: The pods from several South American Prosopis species have been considered relevant food in arid and semi-arid South America since prehistoric times. Traditionally the meal from the pods was processed to prepare different foods and beverages. Objective: The objective was to discuss literature from the archaeological evidence of use to study the chemistry and (bio)activity of the extracts and secondary metabolites occurring in different Prosopis food products. Method: The review was carried out by searching electronic databases, including ScienceDirect, SciFinder, Scopus, Scielo, Google Scholar, PubMed and hand-search on literature. The review mainly covers studies performed in the year 1995-2019 and the first-hand experience of the authors. References on the historical and prehistorical uses of the natural resource were also included. Results: In the last decades, most studies on the edible South American Prosopis focused on the constituents of pods meal, traditional preparations and by-products. Total 45 flavonoids, ellagic acid derivatives, catechin and simple phenolics were identified. Alkaloids occur mainly in the leaves, that are not used for human nutrition but as food for domestic animals. Piperidine alkaloids, tryptamine, tyramine and β-phenethylamine were isolated and identified from several species. The (bio)activity studies included mainly the antioxidant effect, antiinflammatory and enzyme inhibition associated with metabolic syndrome. The products showed no toxicity or mutagenic effect. Conclusions: While data on the chemistry, some (bio)activities and toxicity are available for the pods meal and byproducts, little is known about the composition of the fermented Algarrobo beverages. Further studies are needed on the digestion of Algarrobo products both in humans and cattle.

Antifungal Substances

Contamination of crops with phytopathogenic genera such as Fusarium, Aspergillus, Alternaria, and Penicillium usually results in mycotoxins in the stored crops or the final products (bread, beer, etc.). To reduce the damage and suppress the fungal growth, it is common to add antifungal substances during growth in the field or storage. Many of these antifungal substances are also harmful to human health and the reduction of their concentration would be of immense importance to food safety. Many eminent researchers are seeking a way to reduce the use of synthetic antifungal compounds and to implement more eco-friendly and healthier bioweapons against fungal proliferation and mycotoxin synthesis. This paper aims to address the recent advances in the effectiveness of biological antifungal compounds application against the aforementioned fungal genera and their species to enhance the protection of ecological and environmental systems involved in crop growing (water, soil, air) and to reduce fungicide contamination of food derived from these commodities.

AbstractFungi are one of the most widely distributed microorganisms in the environment, including food such as fruits, vegetables and other crops, posing a potential threat to food safety and human health. The aim of this study was to determine the diversity, intensity and drug resistance of potentially pathogenic filamentous fungi isolated from the fresh raspberries (Rubus idaeus L.). A total of 50 strains belonging to genera Fusarium, Cladosporium, Alternaria, Penicillium, Mucor, Rhizopus, Aspergillus and Acremonium were tested for drug resistance against 11 antifungals by disc diffusion and gradient strips methods. The average mycological contamination in the examined samples of raspberries amounted to 4.34 log CFU/g. The Cladosporium was isolated from all tested samples, followed by Alternaria and Fusarium with a frequency of 61% and 34%, respectively. The highest level of drug resistance was observed for Acremonium genera and Fusarium strains recorded a wide variation in drug resistance as revealed by susceptibility with amphotericin B and voriconzole with MICs ranged from 0.5–4 µg/ml and posaconazole with MICs ranging from 3–8 µg/ml. All fungal strains showed 100% resistance to caspofungin, fluconazole and flucytosine with both the methods, and 100% resistance to micafungin and anidulafungin in the gradient strip method.

Safe food packaging is of great significance in solving food safety problem, which can ensure the quality of the food. At the same time protecting the environment should be taken into consideration, and therefore sound food packaging is not only safe to human health but also green to the environment. In this paper potential safety hazards in food packaging materials and how to develop green food packaging are discussed at length.
