Disinfection Selection and Use

Choosing a disinfectant is a complex process. There is no one best product for all situations. Before deciding on a product to use, answer the questions below to select a disinfectant that best suits your needs. Some disinfectants are effective for routine disinfection at the farm or veterinary clinic level, while others are necessary for outbreak situations.

The health and safety of personnel and animals that may be exposed to disinfectants is always an important consideration.

Physical hazards:

• Slippery floors
• High pressure sprays
• Steam
• Flames
• Dust

Biological hazards:

• Exposure to zoonotic diseases.
• Cleaning and disinfection in contaminated areas.
• Sweeping, scraping and blowing actions may disperse disease agents.
• Inhalation, ingestion and direct contact with disease agents.

Chemical hazards:

• Exposure to chemical irritants, causing eye, skin or respiratory issues.

Prepare a Sanitation Program

• Decide who will manage the sanitation process.

  This includes training employees, ordering supplies, frequency (immediately after use, daily, weekly, monthly), and maintaining sanitation stations.

• What are the disease risks you are concerned about?

  Where on the farm are the risks located? Is there a recurring disease issue that could be controlled by identifying the source(s).

• Learn how different diseases are transmitted.

  What may be brought in by visitors, arrive with new animals or passed to livestock by wildlife. Is a disease spread by aerosols, ingestion, insects or close contact between animals, and what is needed to break the cycle?

• What are the conditions under which a sanitation product will be used?

• What is the type of surface you want to disinfect?

• Choose the correct product.

  Products that are used for daily sanitation may be different than what you need to use when a disease is already present.

• Know what the hazards and safety precautions are with the use of sanitation products.

  Personal protective equipment (PPE) will be needed, and the level of protection required, depending on the product. This information can be found in the product's Material Safety Data Sheet (MSDS).

• Will a quality control process be in place to make sure sanitation is being done correctly?

  Look at boot bottoms, check vehicle tires, create a line of separation, employee compliance with the process, etc.
