Description

This guide is intended to provide confined feeding operations (CFO) owners or operators with knowledge of fly biology, identification of common fly species found in Alberta CFOs, and management options for fly control. The information provided will assist CFO owners or operators in designing and implementing a fly management program specific to their operation. The provided checklists are a tool for CFO owners or operators to help identify sites where flies may be breeding on their operation. They can also be used as weekly cleanup and maintenance schedules for key fly breeding habitats.

Description

The disease balantidiasis is an example of a zoonotic waterborne infection. The protozoan causing the infection, Balantidium coli, is common in swine worldwide in warm and temperate climates, but is rarely reported in Canada. Although there appears to be little risk of acquiring B. coli in Canada, producers should be aware of the disease and its effects on their animals and themselves. The prevalence of balantidiasis in Canada is not known precisely since it is not a reportable disease in people, and few surveys have been conducted to determine its prevalence in swine.

In cattle, the parasite Cysticercus bovis is commonly called bladder-worm or beef measles. This parasite is actually the larvae of the human tapeworm, Taenia saginata. The prevalence of cysticercosis in cattle in Canada is very low. When outbreaks occur, they are usually associated with a human carrier who has had close contact with cattle or cattle feed.

Description

Cysticercosis is an infection caused by the pork tapeworm, Taenia solium. This parasite is found worldwide and is common in countries where raw or undercooked pork is eaten. Although incidences of infection are extremely rare in Canadian and American swine herds, over 1,000 human cases of cysticercosis are reported annually in the United States. Many of these human cases result after travel outside Canada and the United States.

Description

Two species of liver flukes have recently gained attention in Albertaís livestock and game farm industries. One species, the common liver fluke, Fasciola hepatica, has a wide range of herbivore hosts in which it can develop including cattle, bison, sheep, deer, swine and llama. In contrast, the giant liver fluke, Fascioloides magna, has a narrow host range. Wapiti (elk), white-tailed deer and caribou are the main hosts of this latter parasite in North America.

Description

Black flies, which number about 100 species in Canada, occur in varying abundance in all parts of the country. Adult females feed on blood, causing irritation and discomfort to humans, domestic and wild mammals and birds. Apart from the annoyance and discomfort, black flies cause economic losses through reduced beef and milk production, reduced efficiency of agricultural and industrial workers, and spread of diseases. In Canada, black flies transmit blood-borne parasites to turkeys, geese, and ducks. Naive cattle (not previously exposed) have died following a heavy attack by black flies in Alberta.
