Variations in Heavy Metal Contents in Milk and Incorporation of Global Positioning System (GPS) for Food Safety, Soil Chemicals and Agricultural Product Traceability (Legislation Proposal)

Bulletin UASVM Agriculture 01/2009; 2:576. pp.576

ABSTRACT The health of population depends largely upon the quality,
nutritional values, food’s hygiene and its safety. Among many agroproducts,
edible terrestrial snails are a real ecological and silent
animal protein production machines. While delivering many other
nutrients such as vitamins and minerals, snails can also deliver toxic
chemicals. The origin of agro-food starts from soil. Traceability can
be assured by maintaining a record of the chemical testing results
associated with GPS data. EU norms for maximum lead (Pb 0.02
mg/kg) and cadmium (Cd 0.01 mg/kg) contents refer to cow’s milk
whereas sheep’s milk is higher in Pb and Cd contents when the sheep
are fed using pasture in the same area, same soil Pb and Cd levels.
Goat’s milk appears to be virtually free (udl) of Pb and Cd even if the goats are fed
from / on a highly contaminated with lead (Pb = 24.3716 mg/kg) pasture. Legislation needs to
be drafted and refer specifically to the milk of different species. The source of agro-food
products can be identified (Opara, 2003) and it needs to be traced all the way to the soil.

    ABSTRACT: We used Helix pomatia and Helix aspersa species and measure their growth as the snails were approaching the hibernation season. Helix pomatia 2yo shown a decrease in weight while being raised in enclosed parcels of 4sqm the younger Helix pomatia 1yo as well as Helix aspersa Muller demonstrated the ability to adapt relatively fast to the same conditions. We established 5 experimental lots in a Helix pomatia farm, GPS coordinates N46.606040 E23.599950. Control lot contained Taraxacum officinales, Sonchus oleraceus, Equisetum arvense and Atriplex hortensis, wild flora found within the farm. The other lots contained the same plants as the control lot plus different combinations of imported plants from other areals. The H. pomatia 2yo weight decreased in the control lot by a mean of -3.86% while H. aspersa 1yo marked an increase of +16.89% in the same lot during the same period. The lot containing lupinus polyphyllus delivered snails with weight gain of +24.66% for H. pomatia 2yo and an increase of only +1.98% for H. aspersa 1yo. As a contrast, H. pomatia 2yo gained only +7.72% while H. aspersa 1yo gained +28.89%, in the lot containing Lavanda officinalis, Foeniculum vulgare and Hyssopus officinalis among the other plants.
