This study involved blood film examination of 500 healthy blood donors (308 males and 192 females) between the ages of 15-54 years who attended Baptist Medical Centre Eku, Delta State, between August, 2004 and March 2005, 219 (43.80%) were positive for blood parasites; 26 (5.20%) for Trypanasoma, 152 (30.40%) for Plasmodium and 41 (8.20%) for microfilariae. Male blood donors showed relatively higher prevalence (32.20%) than female donors (11.60%). Although parasite prevalence was highest in the age-group 30-34 years, there was no statistical difference among age groups. All blood group types and parasites, though blood group O had the dominant prevalence (44.92%). In addition, the rural-urban prevalence, skewed toward rural blood donors (29.00%), but this was not statistically significant. With respect to occupation, the farming blood donors had the highest prevalence (57.53%) while student donors had the least (14.72%). The study confirms that blood transfusion will always represent a risk, through small to the recipient. Careful and critical examinations of donors to improve good donor selection and transfusion practice are essential.
