Coronavirus – best practice

To avoid transmitting COVID-19 from people to wild mammals, you should:
- stay at least 2 metres from live wild mammals at all times
- only capture or handle live wild mammals if necessary
- avoid going within 2 metres of known breeding or regularly used resting sites of mammals
If you cannot follow these guidelines, then you should:
- minimise the time spent in close proximity and handling mammals
- limit the number of people that come into close proximity or handle mammals
- keep animals separate from other individuals as far as possible
Under this licence, you should follow good hygiene practices, including:
- wearing disposable gloves, or clean and disinfected non-disposable gloves
- wearing a face covering when handling and close to any mammal
- washing hands before and after being close to or handling mammals
Face coverings, non-disposable gloves and overalls or other clothing should be washed or disinfected between uses when handling mammals.

You should not carry out activities under this licence if you feel unwell, test positive for COVID-19 or live with someone who has, or might have COVID-19.

Any products used to clean and disinfect equipment should be safe to use should there be contact with animals and must be used at an effective and safe dilution rate. ‘Safe4’ is an appropriate disinfectant and is considered effective against the virus at a dilution of 1:50. Other products can be used to clean and disinfect equipment.
