Abstract

Animal feed has been linked to human illness through the food chain as a result of food borne bacteria and more recently the risk of foodborne antibiotic resistance. This study investigated the extent to which radiation can be used as an intervention to improve the safety and quality of poultry feed in terms of food borne pathogens and antibiotic resistant microbes. Mean counts of control feed samples were Log10 5.98 for total viable count (TVC), Log10 4.76 for coliform count (CC), Log10 2.89 for Staphylococcus aureus count (STC), and Log10 4.57 for yeast and mold count (YMC) and Salmonella spp. (SC) was not detected (ND). All counts were within permissible levels except for CC (Log10 4.76) which was above the permissible limit of ≤ log10 4.0. Identified bacteria isolates were Enterobacter cloacae (54.5%), Bacillus cereus (27.3%), and Klebsiella pneumoniae (18.2%). All (100%) isolates exhibited multidrug Resistance (MDR) with Bacillus cereus being the most resistant (to 9 out of 11 antibiotics) followed by Enterobacter cloacae/Klebsiella pneumoniae (4 out of 11 antibiotics). Several resistance patterns were observed with PEN/AMP/FLX being the commonest (100%), followed by ERY (90.9%), TET (72.7%), CRX (66.6%), CTX (45.4%), CHL/...Continue Reading
