“…In this study, it was found that mycotoxins negatively impacted on the egg weight and eggshell thickness, which are similar to previous findings [52][53][54]. The reason for loss of egg weight is the presence of toxins, which affects the normal metabolism of the liver, thereby inhibiting both protein synthesis and lipogenesis [55,56].…”

The red-crowned crane (Grus japonensis) is a vulnerable bird species. Mycotoxins are toxic substances produced by filamentous fungi and are considered as naturally unavoidable contaminants in animal feed. Our recent survey indicated that feeds designed for captive red-crowned cranes were contaminated with mycotoxins. This study was conducted to investigate the protective effects of the mycotoxin binder montmorillonite on the reproductive behavior, sex hormone levels, and egg quality of red-crowned cranes. Twelve pairs of G. japonensis were divided into four groups, and each group was fed one of the following: a selected diet (with extra low levels of mycotoxins), a regular diet, a selected diet with 0.5% montmorillonite added, or a regular diet with 0.5% montmorillonite added. Consumption of the regular diet decreased courtship and mating behaviors, testosterone concentration, egg weight, and shell thickness. However, feed supplementation with montmorillonite increased the courtship, mating behaviors and testosterone concentration during the pre-breeding period, as well as egg weight and shell thickness. These findings suggest that the addition of dietary montmorillonite is effective for controlling mycotoxins in the feed, resulting in improvements in reproductive behaviors, testosterone concentrations, and some egg quality parameters of the red-crowned crane.

“…Bryden (2012) reported that the contaminated animal feed is the major cause of exposure of these mycotoxins to animals and therefore ultimately to humans. Negative total aflatoxin in the different types of eggs these results agree with Jia. et al (2016) found that combined aflatoxin (AF) and zeralion (ZEA) contamination showed synergistic effects for decreasing egg production, feed intake, feed conversion ratio and eggshell strength in birds.…”

Humans are exposed to hepatocarcinogenic aflatoxins (Afs) through ingestion of contaminated foods as a result of poor storageful of susceptible grains or eating foods contaminated with aflatoxins animals and vegetables. This work aimed at evaluating the effect level of total (Afs) on human health. Study samples ninety persons divided into three groups (each /30 human). Group (1) no suffering liver disease as normal or negative control. Group (2) patients input (El Raghi hospital in Assuit) are suffering of liver inflammatory disease (HI). Group (3) patients input/or output (El Raghi hospital in Assuit) are suffering of hepatocellular carcinoma (HCC). Random samples were obtained from some foods (chicken egg; chicken, duck and rabbit liver) purchased from local market in Assuit. Total amount of aflatoxins was determined by using high-performance liquid chromatography (HPLC) instrumental. This study used 24 h recall and food frequency questioners for these groups to determination the type and amount of food which were intake. In serum humans measured total aflatoxins by used the enzyme-linked immunosorbent assay (ELISA) kits and ELISA technique. In addition oxidation tests are carried out for the studied individuals by using colorimetric kites to determine liver function (Alanine transaminase (ALT), Aspartate transaminase (AST), Total protein (TP),albumin (Alb), Bilirubin (Total, Direct), alkaline phosphatase (ALP), Glutathione peroxidase (GPX) and Malondialdehyde (MDA) by used spectroscopy instrument. Results indicated that were significant increase in liver function and biomarker antioxidants (GPX, MDA). Study concluded that these alterations in liver functions could be related to the development of liver damage in

“…Ingestion of mycotoxin-contaminated feed by chickens causes several health problems, which leads to large economic losses in terms of egg quality and quantity. The common mycotoxins found in eggs are aflatoxins (AFs), ochratoxin (OTA), zearalenone (ZEA), and fumonisins ( Greco et al , 2014 ; Iqbal et al , 2014 ; Jia et al , 2016 ). In addition, a combination of AFs and ZEA in feeds was shown to synergistically reduce the laying performance, egg quality, and feed intake of laying hens ( Jia et al , 2016 ).…”

Contamination by foodborne pathogens and mycotoxins was examined in 475 eggs and 20 feed samples collected from three egg layer farms, three egg-processing units, and five retail markets in Korea. Microbial contamination with Salmonella species, Escherichia coli, and Arcobacter species was examined by bacterial culture and multiplex polymerase chain reaction (PCR). The contamination levels of aflatoxins, ochratoxins, and zearalenone in eggs and chicken feeds were simultaneously analyzed with high-performance liquid chromatography coupled with fluorescence detection after the post-derivatization. While E. coli was isolated from 9.1% of eggs, Salmonella species were not isolated. Arcobacter species were detected in 0.8% of eggs collected from egg layers by PCR only. While aflatoxins, ochratoxins, and zearalenone were found in 100%, 100%, and 85% of chicken feeds, their contamination levels were below the maximum acceptable levels (1.86, 2.24, and 147.53 μg/kg, respectively). However, no eggs were contaminated with aflatoxins, ochratoxins, or zearalenone. Therefore, the risk of contamination by mycotoxins and microbes in eggs and chicken feeds is considered negligible and unlikely to pose a threat to human health.
