Abstract
1. A comparative study on the effect of different surface decontaminants: hot water at 70°C for one minute; 2% lactic acid for 30 s; 1200 p.p.m. acidified sodium chlorite (ASC) solution for 5 s and 50 p.p.m. chlorine solution for 5 min in the form of dips and sprays on the surface of dressed broilers for 0, 24 and 48 h of storage was conducted. 2. The variables studied were, total plate count (TPC), presumptive coliform count (PCC), pH and extract release volume (ERV). All treatments reduced TPC and PCC. 3. Lactic acid dip and hot water dip were the most effective for reducing TPC (1·36 and 1·28 log/cm2, respectively) with no significant difference between them. 4. ASC and hot water in dip could diminish PCC (1·37 and 1·34 log/cm2, respectively) and did not vary significantly. 5. No treatment affected muscle pH, water holding capacity (WHC), ERV, appearance, smell, tenderness and overall acceptability of treated broilers significantly. 6. Hot water treatment is the cheapest, most convenient and simplest decontamination technique for hygienic and wholesome poultry production.
