When handling animals it is important that your own personal safety is top priority, yet at times this can be something that is overlooked. When dealing with large animals, particularly cattle and horses, events can happen that put us at great risk and many people have been injured, or even killed, by complacency as people are in a hurry to get things done. Preparation, suitable equipment and good facilities are key to providing a safe environment, not only for yourself but also the animals that you are handling. A good knowledge and understanding of the principles of biosecurity and disease transmission are also important, in order to prevent disease spreading from animals to humans, and also from animals to animals.
There are many ways in which disease can be transmitted and this is largely dependent on the pathogen involved. Pathogens need to be able to leave an infected host, survive in the environment, enter a susceptible person or animal and then replicate in the new host. The term 'transmission cycle' is often used to describe this process and the cycle can either be 'direct' or 'indirect' (Table 1.1).
Table 1.1 Transmission routes.
Many pathogens are specific to humans and some specific to animals; however, there are pathogens that are capable of transmitting disease to both humans and animals. A pathogen capable of causing disease from an animal to a human is known as a zoonosis. Knowledge of these pathogens and the diseases that they cause is essential in order to prevent the transmission of disease between the animals we look after and ourselves.
Ringworm is one example of a zoonotic disease. The disease is caused by a fungus and is common in many species, including dogs, cats, horses and cattle. Many animals that are infected show no clinical signs of the disease. People will become exposed by direct contact with the infected areas on the animal and will then show clinical signs (e.g. small circular areas of reddened, inflamed skin that itch) on exposed areas (i.e. hands, neck, lower arms and face). This is prevented by careful observation of the animals that you are in direct contact with and also good personal hygiene.
There are many other examples of zoonotic diseases but it is not the intention of this chapter to provide details on these. What is important is that handlers of animals have a good basic knowledge of some of the more common zoonotic diseases that they are at risk of being exposed to when working with different species. Some of the common zoonotic diseases that handlers should be aware of are outlined in Table 1.2.
Table 1.2 Examples of zoonotic diseases (Hiber and Darling, 2011. Reproduced with permission of John Wiley & Sons.).
In all cases, the risk of disease transmission can be reduced by using a good handwashing technique with soap and water after handling any animal. Wearing the correct personal protective equipment (PPE) is also important.
With some pathogens the host does not always show obvious clinical signs of disease. In these cases, the host acts as a 'carrier' for the pathogen and will be capable of spreading the disease to susceptible animals.
Strangles is one example of a disease that has a 'carrier' status. The disease is caused by bacteria and is common in horses. It is important to note that with this disease there is no risk to humans becoming infected. However, strangles easily transmitted to other horses and, therefore, if you are in contact with an infected horse you must ensure that all necessary precautions are taken with regards to reducing the transmission of the disease. This will include isolation of the horse and putting biosecurity and barrier nursing protocols in place.
The majority of the time that people spend working with animals is with those that are healthy. However, as previously mentioned, it is not always possible to detect that the animals we are working with are ill. Therefore, it is important that handlers are aware of the methods by which the spread of disease can be prevented and controlled.
Whereas biocontainment aims to reduce/prevent the movement of infectious diseases within a facility, biosecurity aims to reduce/prevent the introduction of new diseases into a facility from an outside source.
There are four basic principles to biosecurity:
It should be remembered that biosecurity is not just about protecting the health of the animals in your care but also about protecting your own personal health. It must also be noted that disease in animals does not always show obvious clinical signs, for example animals in the early stage of a disease or carrier animals.
It is important when working with animals that we do so in as clean an environment as possible. Obviously, the degree to which this is done will depend to some extent on the species that we are working with and also the environment in which we are handling the animal. There are some general points to note (Dvorak and Petersen, 2009).
