Contamination most likely happens where the fruits and vegetables are grown, says Barnett. Run off water, nearby grazing animals and birds flying above all can contribute to the problem. A recent study shows that you’re actually more likely to get sick from produce than poultry, beef and even eggs.
The FDA recommends that we wash all fruits and vegetables, even if you only eat what’s on the inside. Any contamination that may be on the surface of the produce may get inside if they are not washed.
They also recommend using a soft brush on produce with hard surfaces and to always wash your hands before handling any food.
Cross contamination can also be avoided by not keeping any raw meat near produce when shopping.
