In a groundbreaking research conducted by the University of Southern California, it has been discovered that anti-microbial resistant bacteria, or ‘superbugs’, can be transmitted to humans through plants. It’s important to understand that these antibiotic-resistant infections pose a considerable threat to global public health, food safety and economic stability. Developing an understanding of how these bacteria are transmitted is instrumental in preventing such infections.
Transmission of Superbugs from Plants to Humans
The transmission pathway of antibiotic-resistant superbugs from plants to humans contrasts with the outbreaks of diarrheal illnesses which typically occur immediately after consuming contaminated vegetables. These superbugs have the ability to colonise the intestines asymptomatically, meaning they can reside there for extended periods without symptoms, ultimately escaping detection and potentially causing an infection.
This study underscores the interconnection between the environment, human health, agriculture, and microbiomes, illustrating the imperative need to view these elements as intertwined rather than separate entities.
Understanding The Term: Superbug
Superbug is a term used to define strains of bacteria that exhibit resistance to most antibiotics commonly deployed today. These resistant bacteria are potent culprits, causing numerous infections including pneumonia, urinary tract infections and skin infections.
All About Antimicrobial-Resistant Bacteria
These antimicrobial-resistant bacteria occur naturally and can be found in a host of locations including humans, animals, food, and the environment (covering aspects like water, soil, and air).

They have the capacity to spread between people and animals, including the food of animal origin, and from person to person. This spread is facilitated by the inappropriate use of medicines, such as when antibiotics are used for viral infections like flu, which should not be the case.
Environmental Factors in The Spread of Antimicrobial Resistance
One way these resistant bacteria magnify the burden of antimicrobial resistance is through inadequately treated sewage waste that contains these bacteria, which then mixes in the environment. Hence, an essential part of controlling and preventing the spread of these superbugs lies in taking environmental factors into account, and strengthening hygiene and sanitation measures.
