. Risk assessment
A significant association between occupational exposure to
swine and human required for infection in primates, cohort, and
caseecontrol studies in humans, and formal risk assessment are
recommended before specific public-health policy actions are taken
[80]. S. suis infection in humans mainly occurs among risk groups
that have frequent exposure to pigs or raw pork. Prevention through
public health surveillance is recommended, especially for individuals
with occupational exposures to swine and raw pork [81].
Although medical complications from farm-related needlestick injuries
do not appear to be common, producers and employees who
inject livestock need to be aware of the related risks and take
measures to decrease unintentional needlestick injury [72].
