All TDS foods are analyzed for elements, pesticides, industrial chemicals, and radionuclides. Certain foods are analyzed for mercury. Refer to the food/analyte matrix on the Foods and Analytes page of this website to determine which TDS foods are analyzed for each analyte group.
TDS foods analyzed for elements, pesticides, and industrial chemicals include results for each of the four market basket (MB) collections that occur each year; radionuclides typically are measured in only one MB each year. Therefore, results for elements, pesticides, and industrial chemicals have four sets of results per analyte, per year; whereas radionuclides typically have one set of results per analyte, per year.
As noted in the introduction, results of the TDS, from 1991 to the present, are available in electronic form on this website, and results prior to 1991 may be found in the publications listed on the publications page of this website. TDS results are presented in two formats:
- Summaries of multi-year results
- Individual results for each year

- 1991 - 2003 sorted by Food (PDF, 5.7MB)
- 1991 - 2003 sorted by Pesticide/Chemical (PDF, 6.2MB)
- 2004 - 2005 sorted by Food (PDF, 86KB)
- 2004 - 2005 sorted by Pesticide/Chemical (PDF, 95KB)
TDS individual-year results from 2003 to the present are in the table below and include separate files for elements, radionuclides, and pesticides and industrial chemicals. For results of individual years from 1991 through 2002, visit the TDS Analytical Results Archive page on this website. Data prior to 1991 are not available in electronic format, but have been published in numerous reports in the scientific literature; see the Publications page on this website.
How to access and understand the files below: Each file is a compressed, tab-delimited text file that can be downloaded, decompressed, and imported into a database or spreadsheet. The data in the files are presented in columns. To understand what each column represents, readers must first access the Individual Year Analytical Results Column Key (PDF, 1MB).
- Some individual pesticide results use number codes to represent the extraction and determination methods used. The codes appear as three- and two-digit numbers, respectively. See Pesticide Extraction and Determination Codes (PDF, 491KB) for a key showing which method each of these number codes represents.
- In the table below, the years listed for radionuclide results (2005, 2004, and 2003) are followed by an additional number (either 1, 2, 3, or 4). The additional number indicates which of the four market baskets collected for that year included radionuclide measurements; for example, 2005-2 means that the food samples tested for radionuclides in 2005 came from the second market basket collected that year.
