Worldwide Occurrence and Impact of Human Trichinellosis, 1986–2009

Abstract

To assess the global incidence and clinical effects of human trichinellosis, we analyzed outbreak report data for 1986-2009.Searches of 6 international databases yielded 494 reports.After applying strict criteria for relevance and reliability, we selected 261 reports for data extraction.From 1986 through 2009, there were 65,818 cases and 42 deaths reported from 41 countries.The World Health Organization European Region accounted for 87% of cases; 50% of those occurred in Romania, mainly during 1990-1999.Incidence in the region ranged from 1.1 to 8.5 cases per 100,000 population.Trichinellosis affected primarily adults (median age 33.1 years) and about equally affected men (51%) and women.Major clinical effects, according to 5,377 well-described cases, were myalgia, diarrhea, fever, facial edema, and headaches.Pork was the major source of infection; wild game sources were also frequently reported.These data will be valuable for estimating the illness worldwide.S ince the mid-19th century, trichinellosis has been a well-recognized meat-borne zoonosis; however, despite concerted control efforts, it remains a threat in many countries.Veterinary control over the slaughter of food animals to ensure food safety, particularly meat inspection, was introduced in Germany in 1866 specifi cally to prevent trichinellosis from pork infected with the muscle larvae of Trichinella spiralis (1).In the European Union, the estimated annual cost incurred from meat inspection of 167 million pigs (2) ranges from €25 million to €400 million (3).Even in countries without mandatory meat inspection (e.g., United States), the economic cost of selling pork in international and national markets is substantial (4).
