Abstract On the basis of the present study the following conclusion can be drawn: 1. Egyptian canned fish foods are highly contained histamine level other than tested foods such as processed meat and cheese. 2. There were predominant bacteria most frequently isolated from Egyptian foods such as Klebsiella pneumoniae, Enterobacter aerogenes, Escherichia coli, Morganella morganii and Proteus vulgaris. 3. Some environmental factors are inhibited histamine formation; 5oC, 7% NaCl (if possible) and killed lactobacilli cells at 2 x 108 cell/ml. 4. Medicinal plants such as Piper nigrum, Zingiber officinale and Cinnamomum zeylanicum were effective in inhibition of histamine formation. 5. A plasmid of Morganella morganii and Proteus vulgaris was very similar in their structure as well as Escherichia coli and Enterobacter aerogenes. 6. Presence of a fragment of DNA (724 pb) in histamine producing bacteria. PDF created. |
