DESCRIPTION:In the 1970's\, a global increase in Salmonellosis
  was noticed\, initially in the USA\, but shortly 
 followed by UK and Europe. The increase was determ
 ined to be associated with a single serovar\, Salm
 onella Enteritidis\, and specific to global region
 s certain phage types of this serovar became preva
 lent. In the earliest outbreaks reported from the 
 USA\, phage type 8 (PT 8) Enteritidis was determin
 ed as the pathogen in the majority of outbreaks\; 
 in the UK phage type 4 (PT 4) accounted for the ma
 jority of outbreaks. In a large proportion of inve
 stigated outbreaks the vehicle of infection was at
 tributed to either eggs or poultry. In the UK\, th
 e `epidemic' started in the mid 1980's\, reaching 
 a peak in 1993. In December 1988\, Edwina Currie t
 he Junior Minister for Health made a public statem
 ent on television stating that "most of the egg pr
 oduction in this country\, sadly\, is now affected
  with salmonella" resulting in her resignation. Th
 e end result of such a public statement ensured go
 vernment interventions were introduced. The interv
 entions primarily involved cleaning up the poultry
  industry and introducing vaccination schemes\, im
 proved farm management including controls for bio-
 security\, pests (vermin) and feeds in addition to
  National Control Plans for Salmonella in Poultry 
 (part of EU wide strategy). Interventions involved
  both the British Egg Industry and national govern
 ment (MAFF / DEFRA) and public health. Following t
 he introduction of interventions between 1993 and 
 1998\, the reported numbers of PT 4 Enteritidis de
 clined. At the peak of the epidemic\, 17\,257 PT 4
  reports were recorded (1993)\, dropping to 6\,744
  in 1999\, 1\,915 in 2005 and 271 in 2011 (0.006% 
 of 1993 figures). In 2011\, the reported numbers o
 f Salmonella Enteritidis PT 4 were 35% below those
  reported pre epidemic in 1982. In the USA\, no su
 ch interventions were put in place\, and improved 
 farm management used instead. In 2009\, the USA is
 sued the largest recall of shell-eggs\, calling fo
 r the removal of half a billion eggs from the mark
