The curve for E. coli is given in the figure, with the most effective UV light having a wavelength of 265 nm. This applies to most bacteria and does not change significantly for other microbes. Dosages for a 90% kill rate of most bacteria and viruses range between 2,000 and 8,000 μJ/cm 2 .
Fungicide residues have been found on food for human consumption, mostly from post-harvest treatments. [16] Some fungicides are dangerous to human health, such as vinclozolin, which has now been removed from use. [17] Ziram is also a fungicide that is toxic to humans with long-term exposure, and fatal if ingested. [18]
