Understanding bacteriophages in food safety practices

The role of bacteriophages in nature

Bacteriophages, often referred to as phages, are biological organisms that serve to maintain the natural balance in a bacterial population. These incredibly abundant life forms, outnumbering bacteria by a factor of 10, have been with us for over a century. Discovered independently by Frederick Twort in 1915 and Félix d'Hérelle in 1917, bacteriophages were recognized for their unique ability to specifically target and interact with bacterial cells. Found in soil, water, and even within our bodies, they play a critical role in nature for regulating bacterial populations within various ecosystems.

How applied phage technology enhances the food industry

Unlike traditional or chemical treatment options that can disrupt the balance of good bacteria in food products, bacteriophages possess the ability to target only specific undesired bacteria, leaving the beneficial bacteria intact. With a unique "lock and key" mechanism that allows them to attach to specific bacterial cells, the phage essentially reprograms the bacterial machinery to produce new bacteriophages instead of more bacteria. This process, known as the lytic cycle, ultimately leads to the inactivation of the targeted bacterial cell.

The food industry is constantly evolving to meet consumer demands for healthy, quality products and transparency regarding ingredients and used interventions. At the same time, the food industry complies with local food safety regulations and practices. Applied phage technology provides a dual benefit by enhancing both product quality and food safety. Each bacteriophage has its ability to target a specific bacterial species, down to the level of bacterial strains. This also applies to well-known foodborne pathogen such as Salmonella, Listeria and E. coli. By applying the right bacteriophages in a commercial and industrial suited solution, they enhance food safety without affecting beneficial bacteria, the organoleptic properties of the treated food products, or causing any harm to humans, animals, or plants. Simultaneously, they are suited for organic processing, clean label products, and can even extend shelf life in certain cases.

Phage technology has seen successful applications in the meat and poultry, seafood, dairy, and more. For further information on how phage technology controls foodborne pathogens such as Salmonella, Listeria and E. coli, visit our website here.

The growing interest in bacteriophages

Research into bacteriophages for food safety and pharmaceutical practices continue to expand, even at a significantly higher pace compared to a decade ago. This acceleration is driven by several key factors:

• Multidrug resistance (MDR): The growing issue of antibiotic resistance, antimicrobial resistance (AMR), and multidrug resistance (MDR) of bacteria for both human therapy and the food industry, has spurred a renewed interest in alternative treatments. Bacteriophages, with their specificity and ability to target seroptypes and strains, have become a focal point in this search. Due to their different approach for detecting and inactivating bacteria compared to traditional antibiotics or antimicrobials, bacteriophages have shown to be unnafected by the growing resistance.
  
  

• Advancements in Biotechnology: Technological advancements in genomics and bioinformatics have enabled more detailed understanding of bacteriophages in the past years, making it easier to identify and apply them effectively.
  
  

• Increased Funding and Research Initiatives: Governments, academic institutions, and private companies are investing more in bacteriophage research. Increased funding has led to a proliferation of studies, clinical trials, and development projects.
  
  

• Regulatory Progress: Regulatory agencies are becoming more receptive to bacteriophages and their various applications. This is evidenced by a growing number of clinical trials and more streamlined processes for approving phage-based treatments, and has led to approval in the U.S. of several Phageguard phage products for the food industry since 2007.
  
  

• Successful Case Studies: High-profile cases were human bacteriophage therapy has successfully treated life-threatening infections have brought more attention and credibility to the field.
  
  

• Collaborative Efforts: There is an increase in international collaboration among scientists, medical professionals, and regulatory bodies to standardize phage applications and share research findings.
