DESCRIPTION:In the 1970's\, a global increase in Salmonellosis was noticed
 \, initially in the USA\, but shortly followed by UK and Europe. The incre
 ase was determined to be associated with a single serovar\, Salmonella Ent
 eritidis\, and specific to global regions certain phage types of this sero
 var became prevalent. In the earliest outbreaks reported from the USA\, ph
 age type 8 (PT 8) Enteritidis was determined as the pathogen in the majori
 ty of outbreaks\; in the UK phage type 4 (PT 4) accounted for the majority
  of outbreaks. In a large proportion of investigated outbreaks the vehicle
  of infection was attributed to either eggs or poultry. In the UK\, the `e
 pidemic' started in the mid 1980's\, reaching a peak in 1993. In December 
 1988\, Edwina Currie the Junior Minister for Health made a public statemen
 t on television stating that "most of the egg production in this country\,
  sadly\, is now affected with salmonella" resulting in her resignation. Th
 e end result of such a public statement ensured government interventions w
 ere introduced. The interventions primarily involved cleaning up the poult
 ry industry and introducing vaccination schemes\, improved farm management
  including controls for bio-security\, pests (vermin) and feeds in additio
 n to National Control Plans for Salmonella in Poultry (part of EU wide str
 ategy). Interventions involved both the British Egg Industry and national 
 government (MAFF / DEFRA) and public health. Following the introduction of
  interventions between 1993 and 1998\, the reported numbers of PT 4 Enteri
 tidis declined. At the peak of the epidemic\, 17\,257 PT 4 reports were re
 corded (1993)\, dropping to 6\,744 in 1999\, 1\,915 in 2005 and 271 in 201
 1 (0.006% of 1993 figures). In 2011\, the reported numbers of Salmonella E
 nteritidis PT 4 were 35% below those reported pre epidemic in 1982. In the
  USA\, no such interventions were put in place\, and improved farm managem
 ent used instead. In 2009\, the USA issued the largest recall of shell-egg
 s\, calling for the removal of half a billion eggs from the market.
