A story on the wires about a paper in the journal Epidemiology this month (November) confirms what other work has shown: those beautiful flowers we buy in American florist shops have an added price attached to them, paid by the children of Central America. Epidemiology is one of the top tier journals in the field of epidemiology, but I don’t have access to my copy, which is at work (and I’m not), so I’m working off wire service copy (Reuters Health). From what I know of the subject, however, the account is likely accurate. Here’s the gist:

In a study from Ecuador, babies and toddlers born to women employed in the cut-flower industry during pregnancy showed poorer communication and fine motor skills than children whose mothers were not flower workers.These children were also nearly five times as likely to have vision problems, the study team found.

Pesticides are used heavily in the cut-flower industry, especially organophosphates, carbamates, and dithiocarbamates, and animal studies suggest exposure to these chemicals before birth may impair neurological development both in the womb and in infancy and childhood.

Alexis J. Handal and her colleagues at the University of New Mexico in Albuquerque used neurodevelopmental testing on 121 children, ages 3 to 23 months, to see if there were differences in fine motorl skills, communication and other neuropsych measures. 52 of the 121 children had mothers who worked in the cut-flower industry while the children were in utero. Test results for communication and fine motor skills were lower for the cut-flower parented children. Decreases of 8% and 13% on scores are reported, but what that translates into is not given in the news articles. However these tests are fairly crude measures of neurodevelopment, so the significant differences seen in this study are worrisome. A more conventional and understandable measure, visual acuity problems, were almost 5 times as likely in the exposed children.

The authors note that working in the cut-flower industry pays a decent wage, although the work hours are long and physically arduous, the more so for pregnant women. It is still not clear the extent to which pesticides or the difficult work conditions are responsible for the observed results, which seem, like the flowers, pretty clear cut.

The cut-flower industry is an important part of the economies of a number of Central South American countries, like Ecuador and Columbia and it employs a disproportionate number of women in their reproductive years.

Another reason to amend trade laws to assure fair labor standards. Few of us would trade brightening our house with flowers from the florist for the health of a child.
