Table 1 A summary of information fields and descriptions for each imported sample recorded in the South African plant import dataset used in the datasheet “List of contaminants on SA plant imports 1994–2019.csv”23.

From: Contaminant organisms recorded on plant product imports to South Africa 1994–2019

Field name

Field description

Standardisation reference

Editing notes

catalogNumber

A unique numerical identifier

NA

This has been added from the original laboratory number in order to anonymize the data. If needed, DS can conduct a trace-back to the original DALRRD laboratory number.

year

Year in which sample was received

NA

Dates were checked chronologically by sample number and incorrect dates corrected (e.g. day & month swapped) Due to confidentiality concerns, DALRRD has decided not to publish exact dates.

month

Month in which sample was received

sample.source

Source of sample

Three sample categories: 1) intervention; 2) audit; 3) post-entry quarantine (PEQ). (see text and Fig. 1 for more detail)

 

country

Country from which the sample originated

United Nations list of accepted country names: https://unstats.un.org/unsd/methodology/m49

The recording of a sub-country location does not necessarily mean that the sample originated from that location. Therefore when city or state was listed, it was replaced with country.

higherGeography

Geographic region

United Nations M49 standard geoscheme: https://unstats.un.org/unsd/methodology/m49

 

crop.vernacularName

Crop, as listed by the border inspector

 

Either the vernacular or scientific name was added, as needed.

crop.scientificName

crop.family

Taxonomic grouping

GBIF (search: 28 Aug 2020)

Where multiple crops were listed, order and/or family was included if these were the same, but recorded as “multiple” if they were not.

crop.order

crop.commodity

Commodity type, as recorded by the border inspector

Table 3: List of import commodity types

The original 9 categories were expanded to 30 and assigned to category based on what was recorded as commodity and crop as well as any additional laboratory records or expert experience.

importer.code

A unique alphanumerical identifier for importer

NA

Anonymization of these data are necessary to protect the confidentiality of the trading companies.

exporter.code

Contaminants (79 columns)

Contaminants, arranged by order or suborder (where appropriate), plus extra columns for unidentified higher taxa

GBIF (search: 29 July 2020) Recorded in Table 2.

Where taxonomy could not be resolved using GBIF, the taxonomy originally recorded was retained.
