ABSTRACT
Meat display tables have been implicated as one of the sources of meat contamination and a critical control point in food processing. Cleaning and disinfection operations are of great importance within the food processing industries for food safety reasons. The effectiveness of four cleaning agents as treatments for the reduction of microbial contamination of meat display tables used by meat sellers at the Bodija municipal abattoir in Ibadan, Oyo state, Nigeria was assessed within April and October, 2009. The treatments include the use of: 1. Pipe-borne water (27oC); 2. Hot water at 85oC; 3. Pipe-borne water and detergent; 4. Combination of pipe-borne water, detergent and sodium hypochlorite. Swab samples were taken from a 1cm2 area on each wooden table surfaces before and after application of each treatment. They were processed and grown on nutrient agar and MacConkey agar to determine the effects of each treatment on total aerobic and coliform counts in the laboratory. The results revealed that all the four treatments had statistically significant difference (P
