An outbreak of gastro-intestinal illness caused by eggs containing Salmonella enteritidis phage type 4.

Seven of nine people developed gastro-intestinal symptoms between 18 and 27 h after eating a trifle with a topping containing raw eggs. Salmonella enteritidis Phage Type (PT) 4 was isolated both from the faeces of affected persons and from eggs remaining in the same box as those used to prepare the topping. The findings show that eggs being produced and sold in the U.K. still contain S. enteritidis PT4 and that this is continuing to cause human infection.
