Abstract

Peeled fruits are fruits which the outer skin which is also called peels or rind have been removed. Most tropical fruits have thick and tough skin that protects them from the climate but are not edible. Fruits are enjoyed by many this could be because it is delicious and has a sweet taste. This study was based on the laboratory assessment of possible pathogenic microbes present in peeled fruits (pawpaw, pineapple and watermelon) sold along Oro-Igwe Road, Port Harcourt. The aim was to identify possible health hazards that can occur because of consumption of such fruits. Fruits were bought randomly from the retailers using a sterile aluminum foil and was swabbed with a sterile swab stick and serial dilutions carried out. An aliquot of 0.1ml was spread on MacConkey and Nutrient Agar culture plate and incubated at 37oC for 24hours. Gram stains were carried out to differentiate the organisms. The polythene bags used in packaging these fruits were also assessed to ensure the source of Staphylocci was isolated. The three (3) different fruits examined for bacteria contamination were pineapple, pawpaw and watermelon. After all the laboratory assessment staphylococci was isolated. These pathogens can cause diarrhea, vomiting, septicemia and bacteriaemia. To stay free of this infection, fruits and handshould be thoroughly washed before consuming these fruits.
