Advances in Applied Microbiology
|September 11, 2012
Summary
Salmonella Enteritidis contamination in eggs remains a significant public health concern. This review examines hen infection, egg deposition, and novel sanitization methods to improve food safety.
Area of Science:
- Food safety
- Microbiology
- Public health
Background:
- Salmonella enterica serovar Enteritidis (SE) egg contamination is a persistent global health issue.
- Despite regulations, illness rates from contaminated eggs exceed targets.
- SE prevalence in eggs and egg products is a key concern.
Purpose of the Study:
- To review Salmonella species contraction by laying hens and egg deposition.
- To highlight the prevalence of SE in eggs and egg products.
- To discuss novel shell egg sanitization methods.
Main Methods:
- Literature review of research on Salmonella contamination in eggs.
- Analysis of factors contributing to SE contamination events.
- Examination of existing and novel sanitization techniques.
Main Results:
- SE contamination in eggs is a complex issue with ongoing research into causative mechanisms.
- Existing control measures have not fully met safety goals.
- Novel sanitization methods show potential for improving egg safety.
Conclusions:
- Further research is needed to fully understand SE fitness for egg contamination.
- Effective mitigation strategies are crucial to reduce illness rates.
- Advancements in sanitization may offer enhanced protection against SE in shell eggs.

01:28Biological Methods for Microbial Control
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:29Methods for Controlling Microbial Growth
Microbial growth control refers to various methods employed to inhibit, reduce, or eliminate microorganisms to ensure safety and hygiene across different settings. These methods are categorized based on the target environment and the level of microbial control required.Biocides are versatile agents designed to control microorganisms by either inhibiting their growth or outright killing them. These agents work through various physical, chemical, mechanical, or biological mechanisms. The...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
