Abstract

This study was carried out to investigate the microbiological and antibiotic resistance profile of bacterial isolates from refrigerated melon soup. Samples for bacteriological analysis were collected from freshly prepared melon (Egusi) soup immediately and subsequently after the 3rd, 7th, 4th, and 21st days of refrigeration. The isolated bacteria were then screened for their resistance profile using commercially prepared discs. The result showed no bacteria growth was observed in the freshly prepared soup. However, a total bacteria count of 0.5 ×10³cfu/ml, 6.0 ×10³cfu/ml, 4.8 ×103cfu/ml, and 5.1 ×103cfu/ml were observed after the 3rd, 7th, 14th, and 21st days of refrigeration/ freezing respectively. The bacterial isolates were Staphylococcus sp, Streptococcus sp, and Bacillus sp. The Antibiotics resistance profile of the isolates showed that Bacillus sp. was resistant to Pefloxacin while Staphylococcus sp.and Streptococcus sp. were resistant to Erythromycin and Gentamicin. This study has shown that bacteria can be isolated from refrigerated/ frozen melon (Egusi) soup and they are resistant to commercial antibiotics. This is of a great public health concern and spoilage could set in learning to food infection and/or intoxication.

Egusi, Streptococcus sp, Bacillus sp and Staphylococcus sp
