The CDC\’s (2014) report on foodborne illnesses helps us understand how these diseases spread and affect public health. It explains the Epidemiological triad, which includes the host, agent, and environment. The host is the person who eats contaminated food, the agent is the harmful bacteria or virus (like Salmonella or norovirus), and the environment includes factors like how food is prepared and stored (CDC, 2014). Transmission happens when contaminated food is consumed, leading to illness.
The report also shows principles of distribution, such as differences in how foodborne illnesses affect various groups of people. For example, children and the elderly are more likely to get sick from these infections (CDC, 2014). The report uses person, place, and time to describe trends. It highlights which groups are most affected (person), where outbreaks happen (place), and how these illnesses change over time (time).
The CDC also uses epidemiologic measures like incidence, prevalence, and rates of infection. The report talks about how many people get sick from different pathogens and how common these illnesses are. Nurses can use this information in several ways. They can educate people about food safety, monitor vulnerable groups like children and the elderly, and help track outbreaks. Nurses can also support food safety programs and advocate for better hygiene and food handling practices (CDC, 2014).

The Centers for Disease Control and Prevention\’s (CDC) 2014 report on foodborne illnesses provides an in-depth analysis of the incidence and trends of infections commonly transmitted through food. The report highlights the importance of understanding the epidemiological triad agent, host, and environment in the context of foodborne diseases. Salmonella serves as the agent; humans, particularly children under five, are the hosts; and contaminated food products act as the environmental conduit for transmission. The transmission cycle is evident when bacteria from animal intestines contaminate food during processing, leading to human infection upon consumption of undercooked products.
The report examines the distribution of these illnesses across various demographics. Children under five experience the highest incidence rates, emphasizing the need for targeted preventive measures in this vulnerable population. Geographically the data indicates variability in infection rates across different U.S. regions, suggesting that local environmental factors and food handling practices influence disease distribution. Temporal analysis reveals seasonal peaks, with certain infections surging during warmer months, likely to increased bacterial proliferation and outdoor food related activities.
The CDC utilizes several epidemiologic measures to quantify these infections. Counts: In 2013, Food Net reported 19,056 infections, 4,200 hospitalizations, and 80 deaths. Incidence Rates: The incidence of Campylobacter was 13.82 per 100,000 population, while Salmonella had an incidence of 15.19 per 100,000. Proportions: Salmonella and Campylobacter together accounted for approximately 70% of reported infections. Trends: Compared to 2010–2012, the 2013 data showed a decrease in Salmonella infections but an increase in Vibrio infections. Descriptive epidemiology in the report focuses on: Person: Children under five years old had the highest infection rates. Place: Incidence rates varied across the 10 U.S. sites monitored by Food Net. Time: Certain pathogens exhibited seasonal trends, with higher incidences in specific months.
The primary purpose of this report is to monitor and evaluate the effectiveness of current food safety interventions and identify areas needing improvement to reduce foodborne illnesses. Nurses can leverage these findings in several ways. Education: Informing patients about safe food handling and preparation practices to prevent infections. Advocacy: Supporting policies aimed at enhancing food safety regulations based on identified trends. Surveillance: Participating in data collection and reporting to help track infection patterns and emerging threats.
By integrating this epidemiological data into clinical practice, nurses play a crucial role in mitigating the impact of foodborne diseases on public health.
