Poultry manure is widely used across the agricultural sector as an organic fertiliser, helping farmers improve soil quality and support crop growth. However, from a Health & Safety perspective, poultry manure presents a range of risks that employers must manage carefully.
Whilst the agricultural benefits are well known, improper storage, handling, transport, or application of poultry manure can expose workers to hazardous dusts, harmful microorganisms, manual handling injuries, and environmental contamination incidents.
Employers have a legal duty to assess these risks and implement suitable control measures to protect employees and others who may be affected by their activities.
In this guide, we'll examine the Health & Safety advantages and disadvantages of poultry manure and explain how employers can use it safely within their farming businesses.
Why do farmers use poultry manure?
Poultry manure is valued because it contains nutrients that support crop growth and can reduce reliance on manufactured fertilisers. It also provides a practical way to recycle agricultural waste and improve soil structure. However, these benefits must be balanced against the health, safety, and environmental risks associated with its use.
What are the Health & Safety advantages of poultry manure?
Reduces reliance on chemical fertilisers
One advantage of poultry manure is that it can reduce the need for synthetic fertilisers. This may lower the frequency of handling certain chemical products and support a more sustainable farming approach. However, employers must still assess and control the hazards associated with poultry manure itself.
Supports sustainable waste management
Poultry manure enables farms to make productive use of a waste product that would otherwise require disposal. Effective manure management can support good environmental practices and help reduce waste accumulation on agricultural premises.
Improves soil quality
When managed correctly, poultry manure can improve soil condition and support healthier crop production. Better soil health may reduce the need for repeated soil treatments and fertiliser applications throughout the growing season.
What are the Health & Safety disadvantages of poultry manure?
Exposure to poultry dust
One of the most significant occupational health hazards associated with poultry manure is exposure to poultry dust. Poultry dust can contain dried faecal matter, feathers, skin particles, feed residues, bacteria, fungi, and other biological contaminants.
Workers involved in cleaning poultry houses, removing litter, loading manure, or spreading manure can be exposed to elevated dust levels. Long-term exposure may result in respiratory irritation and occupational ill-health.
Employers should assess exposure risks and implement controls, including ventilation, safe systems of work, and suitable respiratory protective equipment (RPE).
Exposure to harmful microorganisms
Poultry manure may contain biological hazards, including harmful bacteria such as Salmonella and E. coli. Direct contact with contaminated material or inadequate hygiene practices can expose workers to illness.
Good hygiene arrangements, suitable handwashing facilities, effective training, and appropriate personal protective equipment (PPE) are essential when handling manure.
Manual handling risks
Many manure-handling tasks involve lifting, carrying, loading, and moving materials. Repetitive or awkward manual handling activities can lead to musculoskeletal injuries, particularly where mechanical handling equipment is not used.
Employers should assess manual handling operations and consider mechanisation where reasonably practicable. Training should also be provided on safe lifting techniques.

Slips, trips, and falls
Wet or poorly managed manure storage areas can create slippery surfaces around yards, sheds, and loading areas. This increases the risk of slips, trips, and falls involving workers, visitors, and contractors.
Good housekeeping, effective drainage, and regular maintenance of work areas can help reduce these risks.
Environmental and regulatory risks
Improper storage or spreading of poultry manure can result in environmental contamination. Nutrient runoff into watercourses can lead to regulatory investigations, enforcement action, and reputational damage.
Employers should ensure that manure application rates, storage arrangements, and spreading activities are properly planned and controlled.
Odour and community impact
Poorly managed poultry manure can create significant odour issues, particularly during storage or spreading activities. Whilst often viewed as an environmental issue, complaints from neighbouring properties can also create operational challenges for farming businesses.
How to use poultry manure safely
To minimise Health & Safety risks, employers should:
Carry out suitable and sufficient risk assessments for manure handling activities
Assess employee exposure to poultry dust and biological hazards
Implement safe systems of work for handling, storage, transport, and spreading
Provide suitable PPE and RPE where required
Maintain appropriate hygiene and welfare facilities
Train employees on the risks associated with poultry manure
Regularly inspect manure storage and handling areas for hazards
Monitor environmental risks and prevent contamination of surrounding land and watercourses
How Peninsula can help
Managing poultry manure safely requires more than simply applying fertiliser to land. Employers must consider worker health, biological hazards, respiratory risks, environmental responsibilities, and workplace safety controls.
Peninsula's Health & Safety services can help farming businesses identify hazards, carry out risk assessments, develop safe systems of work, and implement suitable control measures for manure handling operations. We can also provide advice on occupational health risks, respiratory protective equipment, employee training, and compliance with Health & Safety legislation.
Whether you're reviewing existing farming practices or introducing new manure management arrangements, our experts can help you create safer working environments while supporting legal compliance and protecting your workforce.
