Foodborne infections, 1997–2011

Decrease Desired

SOURCE: Foodborne Disease Active Surveillance Network (FoodNet), CDC/NCEZID.
NOTE: Data are for the average number of cases per year of laboratory-confirmed Campylobacter species (objective FS-1.1) and Salmonella species (objective FS-1.4) infections per 100,000 population. Baseline rate is reported as a 3-year average.

Whereas the rate of Campylobacter infections decreased 41.9% between 1997 and 2011, from 24.6 to 14.3 cases per year per 100,000 population, the rate of Salmonella infections increased 17.1% between 1997 and 2011, from 13.6 to 16.4 cases per year per 100,000 population.

Foodborne infections, 2011

SOURCE: Foodborne Disease Active Surveillance Network (FoodNet), CDC/NCEZID.

NOTE: Data are for the average number of cases per year of laboratory-confirmed Campylobacter species (objective FS-1.1) and Salmonella species (objective FS-1.4) infections per 100,000 population.

Rates of Campylobacter and Salmonella infections varied by age. For example, in 2011, children aged 0-4 years had 24.4 cases per year of Campylobacter and 68.3 cases per year of Salmonella infections per 100,000 population. In comparison, older adults aged 75-84 had 14.4 cases per year of Campylobacter and 16.3 cases per year of Salmonella infections per 100,000 population. However, data were unavailable to assess the statistical significance of these between-group differences.

Foodborne infections, 1997–2011

SOURCE: Foodborne Disease Active Surveillance Network (FoodNet), CDC/NCEZID.

NOTE: Data are for the average number of cases per year of laboratory-confirmed Shiga toxin-producing Escherichia coli (STEC) O157:H7 (objective FS-1.2) and Listeria monocytogenes (objective FS-1.3) infections per 100,000 population. Baseline rate is reported as a 3-year average.

The rate of Escherichia coli infections decreased 52.4% between 1997 and 2011, from 2.1 to 1.0 cases per year per 100,000 population. Similarly, the rate of Listeria monocytogenes infections decreased 40.0% between 1997 and 2011, from 0.5 to 0.3 cases per year per 100,000 population.

SOURCE: Foodborne Disease Active Surveillance Network (FoodNet), CDC/NCEZID.
NOTE: Data are for average number of cases per year of laboratory-confirmed Shiga toxin-producing Escherichia coli (STEC) O157:H7 (objective FS-1.2) and Listeria monocytogenes (objective FS-1.3) species infections per 100,000 population.

Rates of Escherichia coli and Listeria monocytogenes infections varied by age. For example, in 2011, children aged 0–4 years had 3.7 cases per year of Escherichia coli and 0.1 cases per year of Listeria monocytogenes infections per 100,000 population. In comparison, older adults aged 75–84 had 0.9 cases per year of Escherichia coli and 1.6 cases per year of Listeria monocytogenes infections per 100,000 population. However, data were unavailable to assess the statistical significance of these between-group differences.

National Snapshots Help

HEALTHY PEOPLE 2020 NATIONAL SNAPSHOTS

A User's Guide

  1. National snapshots provide a visual display of progress for selected objectives in each Healthy People 2020 Topic Area, whenever data are available.

  2. The snapshot heading describes the snapshot theme, the population to which the snapshot applies (when needed for clarification), and the data year(s). The snapshot heading is not meant to capture the full scientific scope of the objective(s) that is (are) displayed. The user can find complete technical information about the objective(s) in the Data Details.

  3. The snapshot visual display is generally one of three types: a line graph, a bar chart, or a map. 

  4. The snapshot notes and footnotes indicate any technical information about the data that the user needs to correctly interpret the visual display, together with any key data limitations (when applicable). Although the snapshots are intended to be standalone, the user should consult the objective(s) Data Details for the full range of methodology issues that may impact interpretation.

  5. The snapshot source(s) indicate the data source(s) used to create the visual display.

  6. Age-adjusted data are adjusted using the year 2000 standard population.

  7. Education and income are the primary measures of socioeconomic status in Healthy People 2020. Unless otherwise noted, income is defined as a family’s income before taxes; thus, the terms “income” and “family income” are used interchangeably in the snapshots.

  8. To facilitate comparisons among groups and over time, while adjusting for family size and for inflation, Healthy People 2020 categorizes family income using the Poverty Threshold (PT), sometimes also referred to as the Federal Poverty Level (FPL), developed by the Census Bureau. Unless otherwise overridden by considerations specific to the data system, the five categories of family income primarily used are: 

    1. Below the PT (i.e., less than 100% of the PT) 

    2. At 100%–199% of the PT 

    3. At 200%–399% of the PT 

    4. At 400%–599% of the PT 

    5. At or above 600% of the PT.

  9. A snapshot narrative paragraph highlights some key features of the visual display. The narrative text is not meant to provide an exhaustive analysis of the data displayed. For a more in-depth analysis, the user should refer to the applicable data table(s) and objective(s) Data Details.

  10. The user should keep in mind the following: 

    1. When two rates or proportions are highlighted for comparison (and measures of variability are available), the user may interpret the highlighted difference to be statistically significant at the 0.05 level, unless otherwise stated.

    2. Only selected differences are highlighted in the narrative text. Differences visible in the visual data display but not highlighted in the text still may well be statistically significant.
