Contaminated shell egg is one of the key Salmonella infection routes for human, causing food-borne illnesses. Multiple salmonellosis infections due to egg contamination still occur in developed countries even though preventive methods, such as vaccination or washing followed by rinsing process, are carried out following certified national standards. Recent outbreaks indicated that current strategies for Salmonella control need to be optimized to further minimize contamination of commercial eggs. Therefore, there is a critical need to develop more sensitive and rapid Salmonella detection methods. In this review, we address (i) egg production; (ii) preventive methods that minimize contamination; (iii) mechanisms of Salmonella contamination; (iv) Salmonella detection methods.

“…Therefore eggshell and membranes can become contaminated during egg development . Several studies have reported positive eggshells and membranes in eggs produced by infected hens (Bichler et al, 1996;Miyamoto et al, 1997;Okamura et al, 2001b). However, as Salmonella can penetrate the eggshell (see Section 8.2) it is difficult to distinguish between contamination during egg formation and that occurring after ovodeposition .…”

Scientific Opinion on the public health risks of table eggs due to deterioration and development of pathogens

Salmonella Enteritidis is considered the only pathogen currently posing a major risk of egg-borne diseases in the European Union (EU). The possible impact of extending the shelf-life of eggs on the risk to consumers posed by S. Enteritidis was estimated by applying a quantitative model and comparing the actual situation regarding the storage of eggs in the EU with different possible scenarios combined, considering the prolongation of the bestbefore and the sell-by date from 7 to a maximum of 70 days. Extending the sell-by date by one week (from 21 to 28 days), but leaving the best-before date unchanged, is estimated to result in a relative risk of illness of 1.4 and 1.5 for uncooked and lightly cooked egg meals respectively, compared to the current situation. If the best-before date is also extended by one week (from 28 to 35 days), the relative risk would be 1.6 and 1.7. In the worst case scenario considered (sell-by date of 42 days, best before date of 70 days), such figures would be 2.9 and 3.5. It should be noted that the absolute risk is greater for uncooked meals compared to lightly cooked meals. An effective way to minimise any increase in risk during extended storage is to keep the eggs refrigerated both at retail and the household. Regarding egg spoilage, such events strongly depend on the hygienic conditions of egg production and practices of egg handling, including storage times and temperatures. Finally, the impact of the prolongation of storage time on the quality criteria for eggs (3-hydroxybutyric acid and lactic acid) destined for manufacturing of egg products is considered negligible. Specifically, EFSA was asked to assess: (i) the public health risk posed by relevant pathogens and in particular by Salmonella in the consumption and handling of table eggs (Term of Reference, or ToR1), (ii) the public health risk deriving from deterioration (ToR2) and (iii) possible consequences for public health of an extended shelf-life of table eggs for the specific freshness criteria for egg products as laid out in the hygiene package (ToR3). © European Food Safety Authority, 2014 KEY WORDSIn order to answer the first ToR, the BIOHAZ Panel based its conclusions on the results of a quantitative model, aimed at describing the behaviour of Salmonella Enteritidis following vertical transmission, since this serovar is recognised to be the major pathogen related to egg-borne disease because of its ability to contaminate the interior of intact eggs during their formation within the body of an infected hen. The possible impact of extending the shelf-life of eggs on other serovars of Salmonella, as well as on other pathogens, is evaluated in a qualitative manner, with no individual serovar other than S. Enteritidis currently posing a major risk of egg-borne salmonellosis in the European Union (EU), although S. Typhimurium has been associated with relatively small outbreaks due to duck eggs. Trans-shell contamination (i.e. secondary contamination) is also discussed, but the impact of a prolongation of the shelf ...

“…Os ovos estão sujeitos à contaminação por Salmonella por meio da infecção do trato reprodutor antes da deposição da casca, a partir da instalação do agente etiológico na gema ou no albúmen (Shivaprasad et al, 1990), durante a passagem pela vagina (Miyamoto et al, 1997) ou, ainda, pelas fezes, quando os micro-organismos penetram pela casca do ovo (De Reu et al, 2006).…”

Os pombos domésticos e silvestres estão distribuídos por todo o mundo e carreiam micro-organismos patogênicos ao homem e a outros animais, podendo ser um dos responsáveis pela disseminação de Salmonella spp. Este patógeno gera grande preocupação para a economia mundial, uma vez que cria transtornos para a indústria avícola quando ocorre contaminação dos plantéis e ônus para a saúde pública devido a surtos de infecção alimentar causados por esta bactéria. Dessa forma, objetivou-se realizar um levantamento acerca da participação do pombo doméstico na possível disseminação de Salmonella spp.
