Europe’s Dinner Plate Dilemma: Antibiotic Resistance in Foodborne Bacteria
European health agencies are sounding the alarm: common foodborne illnesses like salmonella and campylobacter are increasingly resistant to antibiotics. This growing resistance poses a significant threat to public health, limiting treatment options and potentially leading to more severe infections.
The Rising Tide of Resistance
A recent joint report from the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA) confirms that antimicrobial resistance (AMR) in foodborne bacteria remains a major concern. A high proportion of Campylobacter and Salmonella, found in both humans and animals, exhibit resistance to ciprofloxacin, a crucial antibiotic used to treat severe infections.
The situation is particularly worrying with Salmonella. Resistance in human infections has been increasing in recent years. In 2024, over one in five human Salmonella infections resisted ciprofloxacin, with multidrug resistance affecting nearly one in five cases. For Campylobacter, resistance is now so widespread that ciprofloxacin is no longer recommended for treatment.
One Health: The Interconnectedness of Food, Animals, and Humans
Experts emphasize the critical link between human, animal, and food systems. “Antimicrobial resistance in common foodborne bacteria such as Salmonella and Campylobacter highlights the close links between human, animal and food systems,” explains Piotr Kramarz, Chief Scientist at ECDC. This interconnectedness necessitates a “One Health” approach – coordinated action across all sectors to protect the effectiveness of antimicrobials.
The concept of “One Health” recognizes that the health of humans, animals, plants, and the environment are all intertwined. Addressing AMR requires collaboration between healthcare professionals, veterinarians, agricultural experts, and policymakers.
Beyond Ciprofloxacin: Broader Resistance Patterns
The problem extends beyond ciprofloxacin. Both Salmonella and Campylobacter are also showing resistance to other commonly used antibiotics, including ampicillin, tetracyclines, and sulfonamides. This broad resistance limits the available treatment options, potentially leading to longer hospital stays, higher medical costs, and increased mortality.
Increasing Case Numbers and Emerging Threats
Data from the European Union shows a steady increase in foodborne illnesses since 2020. In 2024, there were 168,396 reported human cases of Campylobacter infection and 79,703 cases of Salmonella infection. Factors contributing to this rise include changing eating habits (such as increased consumption of ready-to-eat meals), poor food handling practices, and an aging population more susceptible to infection.
Authorities are also monitoring the increasing detection of carbapenemase-producing Escherichia coli in food-producing animals and meat, a concerning trend as carbapenems are often a last-resort antibiotic for severe human infections.
Positive Trends and Regional Variations
Despite the overall concerning trend, some countries have reported progress in reducing resistance levels in both humans and food-producing animals. Decreased resistance to ampicillin and tetracyclines in Salmonella isolates from humans and poultry, along with decreased resistance to erythromycin in Campylobacter isolates, offer a glimmer of hope.
However, resistance patterns vary significantly between countries, bacteria, and antibiotics, reflecting differences in antibiotic usage, agricultural practices, animal health measures, and prevention strategies.
What Does the Future Hold?
The fight against AMR in foodborne bacteria is far from over. Several factors will likely shape future trends:
Enhanced Surveillance
Continued and expanded surveillance programs are crucial for tracking resistance patterns, identifying emerging threats, and informing targeted interventions. This includes monitoring resistance in both human and animal populations, as well as in the food chain.
Stricter Antibiotic Use
Reducing unnecessary antibiotic use in both human medicine and animal agriculture is paramount. This requires implementing stricter regulations, promoting responsible prescribing practices, and exploring alternative strategies for preventing and treating infections.
Innovation in Antibiotics and Alternatives
Research and development of new antibiotics and alternative therapies are essential to combatting AMR. This includes exploring phage therapy, antimicrobial peptides, and other innovative approaches.
Consumer Awareness and Food Safety
Raising consumer awareness about food safety practices, such as proper cooking temperatures and hygiene, can help reduce the risk of foodborne illness and the spread of resistant bacteria.
FAQ
Q: What is antimicrobial resistance?
A: It’s when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines designed to kill them.
Q: How do I protect myself from foodborne illness?
A: Cook meat, poultry, and eggs thoroughly. Wash fruits and vegetables. Practice good hygiene, such as washing your hands frequently.
Q: What is the “One Health” approach?
A: It’s a collaborative, multidisciplinary approach that recognizes the interconnectedness of human, animal, and environmental health.
Q: Are certain populations more vulnerable to antibiotic-resistant foodborne illnesses?
A: Yes, young children, the elderly, and people with weakened immune systems are at higher risk.
Did you know? The overuse of antibiotics in agriculture is a major driver of AMR. Reducing antibiotic use in livestock is a critical step in protecting public health.
Pro Tip: Always follow food safety guidelines when preparing meals to minimize your risk of foodborne illness.
