How can I contract hepatitis A? / voyages

You can contract the hepatitis A virus by ingesting food or drinks that have been contaminated by human waste. That means, you could be exposed by:

    Eating food handled by an infected worker who did not wash his/her hands properly after using the washroom
    Eating raw or undercooked seafood and shellfish from sewage-polluted water
    Eating produce (e.g. salad) that has been rinsed in contaminated water
    Swimming in contaminated water

Since you can’t see the hepatitis A virus, you can’t tell by looking whether food is contaminated. Even microscopic amounts of contaminated human waste on food can put you at risk.
