Know internal parasites common in your area

9.2 Know internal parasites common in your area The following three procedures can identify the most common parasites in an area:

1. Parasite survey: Manure samples from several animals are examined using a microscope to identify the most common parasites in an area. Information from parasite surveys is often available from government veterinary workers.

1. Autopsy: The bodies of dead or slaughtered animals are examined, particularly the digestive systems and livers. This is an easy way to learn whether liver flukes are a problem because they can be seen in the liver ducts without a microscope.

1. Ask: Other local veterinarians or AHA's may already know which parasites are common in your area. In addition, the Ministry of Agriculture may have useful information.
