Chemical and radiological sample results

MS0570050 , Sanderson Farms LLC

16 of the 52 analytes this system has been tested for have been detected at least once, across 259 samples on record.

The other 36 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.

Across all 259 samples on record, detections range from November 24, 2003 to March 4, 2026. These figures cover the whole record.

What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.

What has been detected, ever

Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

Every analyte ever detected for Sanderson Farms LLC, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 51–60 of 259 samples, newest first — collected September 24, 2018 to August 16, 2021. The summary above covers all 259.

58 results from the 10 samples listed here: 12 detected, 46 not detected. Across the whole record it is 282 of 984. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

Lead is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

We withheld the location of 3 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Sanderson Farms LLC, every result from 51 to 60 of 259 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
