Food recalls seem to be increasingly common in the news, leaving consumers concerned about the safety of their food. Recently, the Centers for Disease Control and Prevention (CDC) investigated an E. coli outbreak linked to McDonald’s Quarter Pounders, resulting in illness and even a fatality. This followed a deadly Listeria outbreak in Boar’s Head deli meat and a voluntary recall of frozen waffles due to potential Listeria contamination. But, are there really more food recalls than before? Let’s explore the factors contributing to this perception and the actual state of food safety.
Understanding Recent Food Safety Events
To understand the current situation, let’s break down the recent outbreaks and recalls:
-
McDonald’s E. coli Outbreak: The source was potentially linked to a sliced-onion supplier. The investigation focuses on identifying failures during the slicing operation or sourcing of contaminated onions. While McDonald’s bears the responsibility for supplier selection and risk management, they generally have a strong record of ensuring product safety.
-
Boar’s Head Listeria Outbreak: Meat plants often have daily inspections from regulatory agencies, which highlights the difference in oversight compared to facilities like onion slicers, which might only be inspected annually by the Food and Drug Administration (FDA).
-
Frozen Waffle Recall: This was a voluntary recall, not an outbreak. The company discovered Listeria in their plant during routine testing and proactively initiated a recall. No illnesses have been linked to the waffles.

Are Food Recalls Actually Increasing?
Food safety incidents like the Boar’s Head and McDonald’s outbreaks appear random. The feeling that these outbreaks are increasing may be due to chance. When multiple events occur within a short period, it creates the impression that the situation is worsening. However, it’s possible that the frequency is normal and we will not see another outbreak in the news for months.
Another crucial factor is the enhanced detection capabilities of the CDC. Through whole genome sequencing of bacteria infecting sick individuals, the CDC can now link cases that might have previously gone undetected. This allows them to identify common sources and initiate investigations, which ultimately leads to more reported outbreaks.

This kind of work allowed investigators to determine that people in the Midwest were sick from the same E. coli infection traced to Quarter Pounders at McDonald’s. Undetected outbreaks like this may have occurred in the past, but now we have better tools to detect them.
E. coli and Listeria: Understanding the Risks
E. coli and Listeria are bacteria. Certain strains of E. coli are pathogenic, and Listeria monocytogenes is also pathogenic.
E. coli can be found in the intestines of warm-blooded animals (humans, cows, deer) and in the environment (soil, water). Listeria is generally an environmental contaminant that thrives in cool, moist environments common in food processing.
These bacteria can contaminate food on the farm or during processing. If they survive the stomach’s acidic environment and attach to intestinal cells, they can cause infection.
Protecting Yourself: Safe Food Handling at Home
Consumers can take several steps to minimize their risk of food poisoning at home:
- Maintain Proper Refrigeration: Set your refrigerator to 40°F (4°C) or lower.
- Use a Meat Thermometer: Ensure meats are cooked to the correct internal temperature.
- Prevent Cross-Contamination: Wash your hands after handling raw meat.
- Clean and Sanitize: Clean cutting boards and surfaces that have contacted raw meat.

Recognizing Symptoms and Seeking Medical Attention
Immediate symptoms of E. coli food poisoning include vomiting, diarrhea, and fever, typically appearing 24-48 hours after consuming contaminated food. Staying hydrated is crucial. More serious conditions, like bloody diarrhea and hemolytic uremic syndrome, can occur. Seek medical attention if you experience bloody diarrhea or diarrhea lasting more than a day with dehydration.
Listeria monocytogenes can cause similar food poisoning symptoms and also a more serious condition called invasive listeriosis. Symptoms of invasive listeriosis can occur days or weeks after eating contaminated food and include fever, muscle pain, septicemia, meningitis, headache, stiff neck, confusion, loss of balance, and convulsions.
Maintaining Perspective on Food Safety
While food recalls are concerning, it’s important to remember that most people eat most foods on most days without getting sick. The CDC’s improved detection methods contribute to the higher number of reported outbreaks.
However, public confidence in the food supply has decreased in recent years, and progress in reducing food poisoning cases has stalled. Despite these challenges, focusing on safe food handling practices and staying informed about recalls can help consumers protect themselves.
Ultimately, while the perception of increasing food recalls might be influenced by improved detection and reporting, vigilance and adherence to food safety guidelines remain crucial for ensuring a safe food supply.
