Input: I just called up customer service and found that since October 2011, all the jars are BPA free. BUT...the jars manufactured before October,2011 are still available in the market. Usually all these products have a long shelf life as they are vacuum sealed. So the jars with BPA lining on the lids are still floating around in the market. The consumers cannot tell the difference. So what is the point in buying this when you do not know if you are giving your baby something that is BPA free or not??? This is very very disappointing from earth's best.
