As far as artefacts go a fruit sticker, found on one of the sites from the
2014 field season, is probably the youngest I have ever looked up. They have
been in use since the 1990s.
During my childhood my family liked to line up the sticker on the side of
the refrigerator, creating a timeline of the different fruits we ate through a
particular period. My mother would wipe the slate, so to speak, frequently, but
we continued the practice well into the time we left home and returned for
extra rations from the supermarket of mom.
I digress.
I learned quite a lot from this little sticker. Firstly, what those numbers
under the barcode present, a livelong question only answered today because I
finally took the time to find out. The numbers are product look-up codes and
represent a standardized number for all fruits and vegetables. The number for a
variant of a particular fruit is the same no matter the location, California or
Georgia. The I
nternational Federation for Produce Standards has taken the codes
even further, meaning a product code will be the same in the United States as
it is in the United Kingdom.
The above sticker gives the product code number of 4383 which represents the
Minneola variety of a tangelo. Minneola is on the sticker, as is USA, but I had
first assumed that was its place of origin (it is from the USA). A
tangelo is a
3 to 3.5 inch cross between a grapefruit and a tangerine. According to
Sunkist
they are in production from December to March. Our fieldwork commenced in
April, which means the sticker is only a couple of months old.
