So can drinking unpasteurized or uncooked milk from infected animals.
VOA: special.2010.07.12
Unpasteurizedmilk can carry salmonella, campylobacter, and E. coli O157: H7, the strain that came to public attention in the nineties when four children died after eating contaminated meat at Jack in the Box.
Where the Pilgrims drank unpasteurizedmilk filled with potentially life threatening bacteria, we fret about drinking anything out of plastic containing BPA, even though Health Canada pointed out that we would need to drink more than 1, 000 liters a day to exceed the safety level (which has an additional safety factor to make the safe level even safer).
