Garden eggs are important economic vegetable crops grown in most tropical countries. The effect of gamma irradiation (1 – 3 kGy), packaging (polyethylene) and storage (5 weeks at 29±1ºC) on the microbiological quality of three varieties of garden eggs (Solanum aethiopicum GH 8772 and Solanum aethiopicum GH 8773, and Solanum torvum) were studied. The population of aerobic mesophiles and yeasts and moulds were assessed by the method of serial dilution and pour plating. Irradiation dose of 3 kGy, significantly improved microbiological quality by reducing the population of aerobic mesophiles and yeasts and moulds in all varieties of the garden eggs. Storing for ≤ 3 weeks negatively affected the microbiological quality of the 2 varieties of Solanum aethiopicum. Solanum torvum was however very susceptible to spoilage at > 1 week. The use of polyethylene packaging did not improve the microbiological quality of the garden egg varieties during storage at ambient temperatures of 29±1oC.
