Biosecurity on your farm involves taking measures to protect the health of your animals and prevent the spread of pests and diseases. The page highlights simple controls such as having one clear entry point, displaying biosecurity signage, using a visitor sign-in form, and setting specific rules for overseas visitors. Emphasis is placed on cleaning and disinfection procedures, especially for visitors' boots. Guidelines for creating specific farm policies and procedures are included, and the page outlines the use of red, orange, and green zones to map out and manage risk areas on your farm.

Anyone coming onto the farm is entering your farm ‘bubble’ and may pose a risk to the health of your animals or bring weeds and pests along for the ride.

To reduce the risk, it’s important to set up some simple controls on your farm.

Reduce the risk

Have one clear entry point - this gives you more control over who and what comes onto your farm.

Biosecurity signage - this reminds visitors that they are entering your farm, and your expectations of visitors. Get your visitor sign at dairynz.co.nz/visitor-sign.

A visitor sign-in form - records who has come, when they arrived, and ensures visitors sign out when they leave.

Overseas visitors - anyone who has visited any country that has foot-and-mouth disease should stay away from susceptible animals for one week after arrival into New Zealand.

 

Farm zone policy for visitors

Use the red, orange, green system to map out zones on your farm.

Red No go areas for visitors, tankers, livestock trucks (i.e paddocks and heifer rearing sheds). Red zones can only be entered after carrying out visitor biosecurity requirements.
Orange Areas that have a mix of cows, farm staff, visitors and equipment (i.e. the milking shed and bobby calf sheds)
Green Areas that have unrestricted access to visitors, their vehicles, tankers and livestock trucks but restricted access by cows (i.e. the milk tanker track, access tracks to houses on farm, bobby calf and slink pick up points).

 

Cleaning and disinfection

Set up a cleaning and disinfection point. This is vital to prevent the spread of diseases and weeds.

All visitors should clean and disinfect their boots. Hand sanitiser or hand washing facilities are also recommended.

Cleaning and disinfection

When washing boots, ensure that all the visible dirt and muck is removed, and pay special attention to the soles. Disinfectant doesn’t work on dirty boots. Spray a generous amount of disinfectant around the bottom and soles of the boots. It’s a good idea for visitors to clean and disinfect their boots again when they leave.

Biosecurity policies and procedures

Set up a farm biosecurity policy that keeps animals in the yards for vet visits and routine procedures and have machinery near the visitor parking area. This means contractors and visitors won't need to go out into your paddocks.

Make sure all your staff know the rules about where visitors can go on farm. Talk through these points with your team:

Who has access?

  1. Do visitors need someone from the farm with them?
  2. Can non-farm vehicles go on the farm races? You might let some vehicles on (like Transpower contractors getting to pylons) but only on set routes.

Other key areas on farm:

  1. Where are beehives located?
  2. Where does pest control work happen?
  3. Have you marked out the high-risk areas on your farm? For example, keeping all visitors out of calf pens.

The key is having clear rules and making sure everyone on the farm knows them.
