Risk to consumers

A very small number of the above eggs may be contaminated with salmonella, due to it being found in the environment. The eggshell surface might also be contaminated. 

Symptoms caused by salmonella usually include fever, diarrhoea and abdominal cramps. 

Our advice to consumers

Consumers should always follow good hygiene and egg handling practices when handling eggs and associated packaging, including:  

  • storing eggs in the fridge until use 
  • using eggs by the best before date 
  • cleaning surfaces and kitchen equipment effectively after use, including the fridge  
  • washing hands thoroughly after handling of eggs, including packaging and eggshells

Anyone who is concerned about symptoms should contact their GP or out of hours service in the first instance. 

Consumers who wish to return the potentially affected eggs should contact the store from where they bought them for further information.
