In the following you will find information on key points regarding Danish pig production. The information material is primarily aimed at foreign employees.

ASF is an infectious viral disease in pigs (including wild boars). It cannot be transmitted to humans. Thus, contact with infected animals does not pose a health risk to humans.
ASF has never been found in Denmark.

Symptoms of African swine fever

You must suspect swine fever if pigs suddenly die or more pigs show one or more of the following symptoms:

  • Fever and decreased appetite
  • Eye inflammation with tearing
  • Red or blue-violet discolouration (preferably on legs, abdomen and ears)
  • Break Inger
  • Constipation (tuberous fertilizer) followed by diarrhea
  • Cramps, uncoordinated movements and staggering hind legs
  • Bleeding

The course of disease in infected animals is rampant and mortality is high. More than 90% of infected pigs die and there is no treatment. There is also no vaccine to prevent the disease.

Notifiable Disease

African swine fever is a notifiable disease. This means that you as an employee must contact your employer, ie. the herd owner, if you notify the slightest suspicion of African swine fever in the herd. Then the herd veterinarian is contacted, who immediately comes and sees the herd.

How are the visiting rules?

If you have been abroad, there are three main rules that apply before arriving to a herd:

  • 24 hour quarantine from crossing the Danish border until entering the area of the herd.
  • Before accessing the herd, clothing and shoes must be changed and you need to bath before you enter the herd area.
  • Food, hunting trophies and live animals brought from abroad are not allowed in the herd area.

There is a difference between staying in a low-risk or high-risk area. Upon arrival from a low-risk area, a 12-hour quarantine from crossing the Danish border is until one has to enter the herd area.


It is important to take good care of the pigs who get sick or get hurt in the herds - these are decisions that include treatment, taking out for nursing and possibly killing the animals that do not thrive.

Danish pig herds have a high level of health and animal welfare. This high level must be maintained, which is why SEGES Pig Production focuses on the correct handling and care of sick and injured animals.


Hernia in pigs is used as a common term for navel-site exposures. Hernia can pose chal-lenges in some herds, and although hernia cannot be completely prevented, there are several steps you can take to reduce the risk of hernia in pigs.

Tail bites

Pig tail bites are a welfare issue that needs to be addressed as soon as it occurs in the herd. It is important to respond quickly to tail bites. The development from minor tail bites to severe tail bites is happening fast. Furthermore, tail bites can quickly spread among the pigs in a path.


Animals normally walk and support equally on all four legs. Please note that tender pigs can be "carried" by other pigs during movement and loading. Therefore, evaluate the pig when it is in free movement without support and without being driven forward.

It is important that everyone who works with pigs comply with the rules for infection pro-tection before accessing a herd upon arrival from abroad. This is crucial to preventing the transmission of unwanted viruses to Denmark.

In Danish pig production, constant efforts are being made to prevent unwanted produc-tion diseases from entering the country. It is important that everyone who works with pigs comply with the rules for infection protection upon arrival from abroad.
