Watermelon is not a commonly allergenic food, is not known to contain measurable amounts of oxalates or purines and is also not included in the Environmental Working Group's 2012 report "Shopper's Guide to Pesticides" as one of the 12 foods most frequently containing pesticide residues.
During the past decade, non-organic watermelons grown in part of
China became the topic of widespread controversy in the popular press
following the use of a synthetic growth stimulator called
forchlorfenuron in their cultivation. A combination of heavy rainfall
and potential overuse of the growth stimulator actually caused many
watermelons on farms in Jiangsu Province to burst open, drawing media
attention to this practice. While we are not aware of any data on
widespread use of synthetic growth stimulators in the production of
non-organic watermelon, we have seen one study predicting residues of
forchlorfenuron in the range of 1-5 ppb in watermelons raised with the
use of this synthetic growth stimulator. If you are seeking to lower
your risk of contamination with all synthetic additives in watermelon
and other foods, we recommend purchase of certified organic watermelon,
since synthetic growth stimulators and other synthetic additives are
prohibited in organic food production.
