Mantra for thanking and blessing Mother Earth

Student: Sir, Is there any chanting to bless our vegetables and groceries so they don't carry the contamination while we are getting them home for consumption?

Naran Sir: OM VASUDAAYAI SWAHA

When we chant this mantra, we are thanking and blessing Mother Earth for providing us with the Divine food for nourishing our bodies.

We can chant it while buying the food or while bringing it into the house or while cooking, serving, eating food.
