Summary
Microbial contamination in prawns from Cairo and Giza markets was assessed. Counts of bacteria like Aerobes and E. coli increased in processed samples, posing public health risks.
Area of Science:
- Food Microbiology
- Public Health
- Microbial Contamination
Background:
- Prawns are a popular seafood, but can harbor various microorganisms.
- Assessing microbial loads in commercially sold prawns is crucial for food safety.
Purpose of the Study:
- To evaluate the microbial contamination levels in prawns from markets in Cairo and Giza.
- To identify specific bacterial groups present and discuss their public health implications.
Main Methods:
- Collected 110 prawn samples from markets in Cairo and Giza Governorates.
- Quantified aerobic bacteria, psychrophiles, Enterobacteriaceae, coliforms, and staphylococci.
- Isolated specific bacterial groups including Escherichia coli and Staphylococcus aureus.
Main Results:
- Average bacterial counts (Aerobes, Psychrophiles, Enterobacteriaceae, Coliforms, Staphylococci) were determined.
- Significantly higher bacterial counts were observed in raw (in-shell and peeled) and frozen (peeled and in-shell) prawn samples.
- Various bacterial groups, including Escherichia coli and Staphylococcus aureus, were isolated.
Conclusions:
- Prawns from the studied markets exhibit microbial contamination.
- Processing and storage methods can increase bacterial loads, highlighting potential public health concerns.
- Further investigation into the public health significance of isolated pathogens is warranted.
