Consumer awareness is the paramount issue here and as long as a consumer is asking for information, then it should be legally required. I have personally been struggling for years with the FDA with similar requirements. I have always been concerned that fruits and vegetables harvested during full moons is potentially more dangerous if consumed in excess.
I have yet to come up with conclusive evidence of how the lunar cycle affects produce harvests, but neither have the deniers decidedly refuted the theory. In fact, "scientists" whom I have asked about the theory have explicitly stated that my request to prove a negative condition is a logical impossibility. This only serves as evidence to me that we will never be able to be certain about our produce health.
The only reasonable conclusion is that it should be left up to informed consumers. If it is true that the lunar phase has no effect on the food, then food manufactures should have no reason to avoid this labeling proposal. Please join me in the fight and sign the petition.
