The Big 6 Foodborne Pathogens and How to Identify Them
Understanding Foodborne Pathogens and Ensuring Food Safety
Did you know that pathogens contaminate some foods? Foodborne pathogens are viruses, bacteria, or parasites that are dangerous to ingest. Consuming contaminated food or beverage can lead to foodborne illnesses. The Big 6 is a group of the most highly infectious foodborne pathogens, meaning they are more easily transmissible among food handlers.
These pathogens have a low infectious dose, contaminate the gastrointestinal system after ingestion, and are shed in large numbers through feces. Even when practicing thorough handwashing, the Big 6 can be transmitted easily from food handlers to consumers or other workers. However, if you practice food safety correctly and undergo food handler training, you can avoid infection altogether. First, let’s learn about what symptoms to watch out for.
The Big 6 and Their Symptoms:
How can a food handler identify pathogensSalmonella
Symptoms include mild to severe diarrhea, fever, and abdominal cramps within 12 to 72 hours of infection. This illness can last 4 to 7 days in most cases, but in more severe cases, infected persons should be hospitalized for treatment.Shigella
Shigellosis can cause diarrhea, fever, and stomach cramps within 1 or 2 days after exposure. Shigella may still be passed to others even when the initial consumer exhibits no symptoms. This disease usually clears up within 5 to 7 days.E. coli
Many strains of E. coli are benign, but others cause sickness. While some cause diarrhea, others can cause respiratory illness, pneumonia, urinary tract infections, and other illnesses.Hepatitis A
This infectious disease develops when the hepatitis A virus is transmitted through food contamination or the fecal-oral route. Symptoms include fatigue, nausea, stomach pain, low appetite, and jaundice. These usually clear up within two months of infection. Children 6 years old and younger often do not show symptoms.Nontyphoidal Salmonella
This infection can cause fever, diarrhea, abdominal pain, nausea, and vomiting. These symptoms occur within 6 to 72 hours after ingestion of Salmonella and can last 2 to 7 days.Norovirus
This highly contagious virus is transmitted by contaminated food and beverage, surfaces, and infected people. As a result, the stomach and intestines may become inflamed, leading to nausea, diarrhea, stomach pain, and vomiting. These symptoms can range in severity.Preventing Infection
