American Council on Science and Health Debunks "Roses are Toxic" Myth
Last year, a press release regarding the safety of workers on flower farms was misinterpreted by the press, and reporters mistakingly claimed flowers were hazardous to consumers. This claim became #6 on the American Council on Health and Science's "Top 10 Unfounded Health Scares of 2007".
The ACSH concludes:
There is no evidence showing that exposure to pesticides at trace levels causes any adverse health effects. High doses of the chemicals can pose a threat, and therefore it is important that the safety of workers is made a top priority. However, there is no evidence of low-level exposure to pesticides causing cancer or other health problems.
In other words, Columbian flowers are safe for consumers.
