Pig keepers warned not to feed kitchen scraps to pigs due to African Swine Fever risk

Date published: 07 February 2018

Pig keepers are being reminded not to feed kitchen scraps to their animals to prevent outbreaks of animal disease.


The warning comes after an increase in the risk level of African Swine Fever (ASF) entering the United Kingdom, following spread of the disease in Eastern and Central Europe.

There has never been a case of ASF in the UK and while it does not affect humans, it is potentially fatal to pigs. If the disease were to reach the UK it could have a devastating effect on export markets and would also require the humane culling of pigs on infected premises to prevent further spread.

Keepers are being reminded that it is illegal to feed catering waste of any description or domestic food waste to farm animals in the UK, including pigs kept as pets as some of the outbreaks of ASF in Europe have been attributed to wild boar or domestic pigs consuming contaminated pork or pork products. Viruses such as foot and mouth disease could also be introduced to the UK through food products. This includes food from vegetarian kitchens as there is still a risk of cross contamination from products of animal origin such as milk.

Strict hygiene measures are essential in preventing disease – people should not take meat or meat products into areas where pigs are kept and should only eat food in designated areas such as staff rooms or the farm kitchen. Pig keepers, farm staff and anyone in contact with pigs should wash their hands before and after eating or preparing food.

Northern Ireland’s Chief Veterinary Officer, Robert Huey said: “The introduction of African Swine Fever would have an enormous impact on our pig industry. No matter how many pigs you keep, you need to be aware of the potential consequences of feeding waste food to your animals. Not only is it illegal, but you run the risk of spreading disease which could be fatal to your livestock.

“You can purchase a range of pig foods from your local agricultural merchant that can be safely fed to your pigs and which is the most reliable way of giving them a balanced diet. Good biosecurity is also essential for minimising disease risk, such as providing dedicated clothing and boots for workers and preventing vehicles which may be contaminated from entering pig premises.”

The UK suffered the consequences of pigs being fed illegal waste food in the Foot and Mouth Disease outbreak in 2001. That outbreak is thought to have originated from pigs being fed catering waste containing the virus, which came from outside the UK. The outbreak resulted in the destruction of more than 10 million cattle and sheep, and cost the UK many millions of pounds.

Norman Robson, Ulster Farmers’ Union said: “The health of our pigs is fundamentally important to our sector. A notifiable disease outbreak would not only needlessly result in the loss of many pigs and have devastating effects on our export market, but would significantly impact on countless families, their staff, local businesses and tourism for months. Feeding illegal food waste, however harmless it might seem at the time, is just not worth the risk.”

Notes to editors: 

  1. African swine fever (ASF) is a highly contagious viral disease of pigs.  It can be spread through direct contact with infected pigs, faeces or body fluids; indirect contact via fomites, such as equipment, vehicles or people who work with pigs between pig farms with ineffective biosecurity; pigs eating infected pig meat or meat products and biological vectors – ticks of the species Ornithodoros. However, ASF competent ticks are not present in the UK.
  2. European Union wide animal by product legislation states that feeding farmed animals with catering waste or feed material containing, or derived from catering waste, is illegal. Doing so can result in prosecution.
  3. Fruit and vegetable material that originated outside the kitchen, which has never entered the kitchen, and which has not come into contact with material of animal origin can be fed, such as vegetables from domestic gardens. Some commercial food waste can also be fed if it has undergone the correct animal by-products processing and meets the requirements of the Feed Hygiene Regulation. The safest option if you are in doubt is not to feed any food waste to your animals.
