as for the lead content, from what i found looking it up (not much information)
CA law says that even if 1/1000th of the amount toxic to humans is present, it needs to be listed so the amount in the baby food is probably the equiv to a grain or two of salt per 4 oz.
so if 1 oz of "lead" is toxic, then if there is 1/1000th of an ounce of "lead" in the veggies, it needs to be listed.
from a 2007 study on grown carrots.
" Old orchard soil had a lead level of 496 mg kg(-1), compared with 6.52 mg kg(-1) for non-orchard soil. Peeled carrot roots from old orchard soil contained 0.885 mg kg(-1) lead, and peeled roots from non-orchard soil contained 0.147 mg kg(-1) lead." that is NATURALLY occuring in the product.
now lets see, using wikipedia 0.0147 mg= 147ug(micrograms) per kg (atleast that is what i assume that kg(-1) means if someone knows definitively that it is not a kg then let me know..
symptoms of lead poisoning appear ~ anywhere between 20-60 ug/dl = 20-60 micrograms per decileter
a deciliter is 100grams & a kg is 10 deciliters ...so
200-600 micrograms of lead per kg= symptoms MIGHT appear.
carrots in that study had 147 micrograms per kg of naturally occuring lead in the carrots- the carrot absorbed the lead naturally in the soil
so according to the study, the 147 micrograms of lead in the not orchard soil carrots= not toxic , BUT according to CA law, since it is more than 1/1000th of the toxic level, it needs to be listed and warned about.
interestingly the old orchard soil would be "toxic" to children eating the carrots grown in it (885 micrograms per kg)
anyone actually believe that is so?
