Salmonella → contaminates → eggs
“Salmonella contamination of eggs and egg shells has been identified as a public health concern worldwide.”
Salmonella → grow → shell eggs
time: 2 daysstorage_condition: room temperature
“The organisms also grew rapidly in eggs stored at room temperature and after 2 days the number of cells per gram of yolk exceeded log10 8.0.”
Salmonella → survive → shell eggs
cooking_condition: some yolk remains liquid
“Strains of Salmonella enteritidis, S. typhimurium and S. senftenberg inoculated into the yolks of shell eggs were found to survive forms of cooking where some of the yolk remained liquid.”
shell eggs → are associated with → Salmonella enteritidis outbreaks
“Salmonella enteritidis outbreaks were significantly more likely than outbreaks of other serotypes to be associated with vehicles containing shell eggs, suggesting that eggs were also the source of infection in many outbreaks.”
Salmonella Heidelberg infections → increased risk → consumption of undercooked eggs
matched odds ratio: 7.595% confidence interval: 1.5-75.5
“Consumption of home-prepared chicken nuggets and/or strips [matched odds ratio (mOR) 4.0, 95% confidence interval (CI) 1.4-13.8], and undercooked eggs (mOR 7.5, 95% CI 1.5-75.5) increased the risk of illness.”
Salmonella enteritidis → found → in 32 eggs (0.6%)
“Thirty-two eggs (0.6%) were positive in the contents”
Salmonella enteritidis → found → in many thousands of cells in three eggs
“Three eggs, however, were found to contain many thousands of cells”
Salmonella enteritidis → more likely → to be heavily contaminated in eggs held for more than 21 days
“those held for more than 21 days were more likely (P less than 0.01) to be heavily contaminated”
Salmonella → isolated from → 5 isolates from eggshells after processing
“All five isolates obtained from eggshells after processing were serotyped as S. heidelberg.”
Salmonella → survive → shell eggs
cooking_condition: any mannercontamination_level: log10 8.0 cells per gram of yolk
“With this level of contamination viable cells could be recovered from eggs cooked in any manner.”
