Pigeons are scavengers (not fed any supplementary feed) in most countries, living on the roofs of houses and treated as “pets” that do not need to be fed. They appear to prefer homestead compounds to fields. In some countries, they are eaten only for ritual purposes. They normally lay two eggs in a clutch, and the young birds (squabs) hatch after 16 to 17 days. The growing squabs are fed by their mothers on crop milk, produced in the mother’s crop (first stomach). This enables young squabs to grow very rapidly. They reach maturity in three to five. | DOI Suggested citation for this article Sears A Baker MG Wilson N Marshall J Muellner P Campbell DM et al.

Lake Beginning in the early 1980s New Zealand experienced rising annual rates of campylobacteriosis that peaked in 2006. We analyzed notification hospitalization and other data to explore the 2007-2008 drop in campylobacteriosis incidence. Source attribution techniques based on genotyping of Campylobacter jejuni isolates from patients and environmental sources were also used to examine the decline. In 2008 the annual campylobacteriosis notification rate was 100 000 population representing a 54 decline compared with the average annual rate of 100 000 for 2002-2006. A similar decline was seen for hospitalizations. Source attribution findings demonstrated a 74 95 credible interval 49 -94 reduction in the number of cases attributed to poultry. These reductions coincided with the introduction of a range of voluntary and regulatory interventions to reduce Campylobacter spp. contamination of poultry. The apparent success of these interventions may inform approaches other countries could consider to help control foodborne campylobacteriosis. Campylobacteriosis is a common bacterial gastroenteritis reported in New Zealand and many other industrialized countries with most cases caused by
