Combating Persistent Bacteria in Broiler Houses

Maintaining a hygienic environment in the poultry industry is crucial for broilers' health and productivity. Despite rigorous disinfection protocols, certain pathogenic bacteria persist in broiler houses, posing significant challenges to crop performance. Here, we explore how Enviro Spore helps eliminate these pathogens and improve overall environmental cleanliness.

Combating Persistent Bacteria in Broiler Houses

Even after thorough disinfection, several types of airborne bacteria are commonly found in broiler houses, including:

1. Escherichia coli (E. coli): Known for its resilience, E. coli often persists in floor cracks and drinking cups, even after cleaning.

2. Salmonella spp.: Particularly Salmonella Enteritidis, this bacterium can survive disinfection, making stringent hygiene practices essential.

3. Clostridium perfringens: Associated with necrotic enteritis, this bacterium remains a challenge in broiler environments despite disinfection efforts.

4. Staphylococcus spp.: Including Staphylococcus aureus, these bacteria quickly re-establish themselves after disinfection.

5. Pseudomonas spp.: Notable for forming biofilms, Pseudomonas aeruginosa and other species are commonly found on drinking water systems.

Opportunistic Aerosolised Bacteria after Placement.

E. coli and Staphylococcus spp. becomes aerosolised from dust, feather dander, and bedding, leading to infections upon inhalation. Pseudomonas spp. can be aerosolised through moist environments and water systems. Additionally, bacteria such as Salmonella, Clostridium perfringens, and Enterococcus spp. persist in the litter and can infect broilers through skin contact or inhalation of dust particles. Although its main route to infection is ingestion, infection through the skin is still significant. Enviro Spore combat these bacteria by colonising the environment and outcompeting harmful pathogens, thereby reducing the risk of infection.

How Pathogenic Bacteria Survive the Turnaround.

Deep in Concrete Substructures

Pathogenic bacteria have several strategies to survive even after rigorous cleaning and disinfection:

Deep in Concrete Substructures: Concrete floors and walls in broiler houses often have tiny cracks and crevices where bacteria can hide. These microenvironments protect bacteria from surface disinfectants. Organic matter and moisture accumulate in these cracks, providing nutrients and habitat for bacteria like E. coli and Salmonella.

Biofilms In Walls and Equipment:

Some bacteria, such as Pseudomonas spp., form biofilms, a complex aggregation of microorganisms encased in a self-produced matrix. These biofilms can adhere to surfaces like walls and equipment, making the bacteria within them highly resistant to disinfectants.

The Role of Enviro Spore.

Enviro Spore microbes offer an innovative solution to combat these persistent pathogens. These beneficial microbes work actively in the broiler bedding, walls, and other surfaces, creating a healthier and safer environment for the birds. However, it is important to note that Enviro Spore is not a replacement for disinfectants but works best following stringent disinfection protocols.


Once disinfection has significantly reduced bacterial levels, Enviro Spore microbes are introduced into the clean environment. They quickly colonise the surfaces, establishing a beneficial microbial community before pathogenic bacteria can take advantage of the newly disinfected environment.

Competitive Exclusion and Inhibition.

Enviro Spore microbes produce several compounds that inhibit the growth of pathogenic bacteria through competitive exclusion and the production of peptides and molecules. By colonising the bedding, walls, and other surfaces, they limit the availability of nutrients for harmful bacteria. Reducing the population of these pathogens, lowering the risk of infections. Additionally, Enviro Spore continues to inhibit the growth of pathogenic bacteria into the microenvironments within the walls and concrete substructure.

Proven Inhibition of Pathogenic Bacteria.

Studies have demonstrated that Enviro Spore microbes inhibit the growth of pathogenic bacteria. They produce antimicrobial substances that directly kill or inhibit the growth of pathogens like E. coli, Salmonella, and Clostridium perfringens. This not only reduces the number of harmful bacteria but also prevents them from re-establishing in the environment.

Implementation and Monitoring

To maximise the benefits of Enviro Spore, it is essential to integrate their use into regular biosecurity and hygiene protocols.


Enviro Spore microbes represent a promising approach to enhancing biosecurity in broiler houses. By targeting persistent pathogens and improving the overall microbial environment, these beneficial microbes help reduce disease incidence, improve bird health, and support sustainable poultry production by reducing AMR bacteria.

Enviro Spore offers an effective solution to the challenges posed by persistent bacteria in broiler houses as part of a comprehensive biosecurity strategy.
