Business of poultry in Jordan, contributes huge proportion towards economy and is considered as one of the chief industrial sectors. Poultry chicken is a source of protein which costs less as compared to other animal proteins1. Therefore, poultry feed is the keystone of poultry industry, which accounts of more than 60% of the expenditures in production process. The infected poultry feed has become the main focal point of scientists in the whole world including Jordan. Because; it is the major source for hazardous and toxic substances which leaves negative impacts on human health and leads towards cancer, observed in Jordan2. Contamination of poultry feed with mycotoxins e.g. ochratoxin is which are groups of fungal metabolite consists of three types, A, B and C. Among them, Ochratoxin A (OTA) is the most widespread and the most toxic3,4.
Usually, in presence of optimum environmental conditions for fungal growth; OTA is formed through direct fungal contamination to crops and animal feed in the field or post-harvest season5,6. Ochratoxin is much perilous to the health of humans as well as poultry because of their carcinogenic impacts. Whereas; in broilers, symptoms after consuming feed contaminated with OTA are: poor growth, reduced feed efficiency and increased water consumption (consequence of damaged kidneys)7,8. Moreover, long term exposure to Ochratoxin A could result in high mortality rate4.
Nazieh .I. AL khalaileh designed an experiment to examine the scale of contamination of poultry feed and meat with Ochratoxin A in Jordan by using Enzyme Linked Immunosorbent Assay. Afterwards; comparison was done with maximum level recommended by the European Commission and some countries in the region. For this purpose; almost 129 samples representing feed, corn and poultry meat were gathered from different territories of Jordan market and evaluated for Ochratoxin A by ELISA. It was observed that round about 38.5% of feed sample, 50.0% of corn sample, 100.0% of feed sample found under sun light were containing an Ochratoxin A (OTA) with an average concentration of 2.90±0.26, 2.35±0.32, 10.30±0.59 μg kg–1, respectively. This investigation also exhibited that between 66.0% (12 sample) to 100.0% (54 sample of the analyzed organs meat sample contains OTA with a concentration ranging from 1.89±0.07-7.68±0.12 μg kg–1.
It was noted noted that none of the tested samples exceeded the maximum limit set by the EU limits of <50.0 ng km–1 in poultry feeds. In addition, researcher also observed that the consumption of OTA on daily basis through chicken meat depends on the OTA concentration in the food. Conclusively; this research will definitely raise awareness about the importance of legislation and laws that show the safe level of ochratoxins allowed in poultry feed and meat at national and regional level.
