Health problems in agriculture

Agricultural workers are potentially exposed to several health problems due to working conditions on farms. Health problems caused by work can develop unnoticed, and in some cases may not appear until much later in life. You need to be aware of the health risks associated with your work and the signs or symptoms of developing ill health.

You should report any signs of illness to your employer as soon as you become aware of them. Don’t be afraid to visit your doctor. Make sure he or she knows what you do for a living so they can start treating you as early as possible.

Early diagnosis and treatment may prevent your condition from worsening and may even save your life.

You must report some health problems suffered as a result of work to HSE.

Chest problems

The main causes of respiratory disease or chest problems are dusts or chemicals at work. Being exposed to these for just a short time may cause unpleasant irritation or inflammation in the nose, throat or lungs. Longer exposure may lead to more serious problems, including asthma and chronic bronchitis.
Chest problems may result from breathing in:

  • dusts from harvesting or handling grain, mixing animal feedstuffs, feeding animals, handling mouldy hay or bedding and waste products from animals or poultry;
  • vapours from slurry, silage, welding fume, some veterinary medicines and disinfectants.

It is important to protect yourself and your workers. For products that you buy, follow the advice and instructions on the manufacturer’s label or data sheet.

Zoonoses - Diseases that animals pass to humans

Types and symptoms

Zoonoses are diseases that animals pass to humans. Micro-organisms such as bacteria, fungi, parasites and viruses can cause illness by infecting the body when they are breathed in, swallowed, or when they penetrate the skin through small cuts or grazes.

Common zoonoses include:

  • orf from sheep or goats, which produces painful pustules on hands, arms and the face;
  • leptospirosis from rats (Weil’s disease) and cattle urine, which causes a feverish illness with headache and can result in meningitis. Early treatment is vital;
  • ringworm, which is a fungal disease from many types of livestock;
  • enzootic abortion (chlamydia psittaci) from sheep. Pregnant women should not associate or work with ewes during lambing, nor be exposed to soiled clothing contaminated with afterbirths etc as severe illness and miscarriage may result;
  • cryptosporidiosis, from a parasite picked up by touching livestock, animal housing, or feed, which can cause diarrhoea in humans, and be particularly severe in young children;
  • Lyme disease, from the bite of an infected tick in woodland or grassland. Starts with a rash around the site of the bite and intermittent flu-like symptoms. More serious symptoms affecting the nervous system may develop later. Early diagnosis is essential;
  • Q fever from cattle and sheep can also be carried by other mammals, including deer. Leads to acute illness with feverish symptoms but occasionally pneumonia and other complications. There is also a more serious chronic form of Q fever;
  • ornithosis (another form of chlamydia psittaci) from birds, which can cause flu-like symptoms in humans, followed by pneumonia.

Diseases transmitted from animals to humans can also affect visitors to your farm, especially children or the elderly. Illness following infection by some virulent forms of E coli bacterium, eg O26 and O157, may be severe and even fatal. Any ruminant (cattle, sheep, goats and deer) may carry the organism, which can survive for many weeks in faeces or soil. Good personal hygiene is essential.

Skin problems

Preventing damage to the skin will reduce the risk of problems such as contact dermatitis, eczema, wound infections and skin cancers.

Warning signs include dryness, cracking, irritation, itchiness and pain, inflammation and redness, and abnormal growth or discolouration. If you have ever suffered from eczema, your skin may be more vulnerable to damage.

Musculosketal Disorders (MSDs)

Many workers suffer from various ‘musculoskeletal disorders’ (MSDs) as a result of poor manual handling techniques, or through other tasks which involve repetitive movements, excessive force, unusual postures, or from badly organised working practices.

These can include muscle injuries, sprains or strains, back pain, sciatica, hernias, arthritis, or swelling of the hand, wrist, forearm, elbow and shoulder (‘work-related upper limb disorders’ or WRULDs). People may not fully recover from these, affecting their ability to carry out any manual work in the future.

Further information

Work-related stress

Stress is the reaction people have to excessive pressure or other types of demand placed on them. Many people in agriculture work under pressure, eg from conflicting demands, too much to do in too little time, or working with inadequately controlled hazards.

You can get independent, trained help and information from charities such as:

You can get more advice on health problems in agriculture from your GP, from HSE’s medical inspectors, or from other health and safety professionals, including occupational health doctors and nurses and occupational hygienists.

Chemical related problems

Pesticides, Veterinary medicines and sheep dips may contain hazardous substances. If mishandled, they can make you ill, harm animals or pollute the environment.
