New research suggests that many adults have been bitten by certain ticks. These ticks can cause health issues in people who are bitten. The problem is linked to a specific type of tick that is common in some areas.

People who are bitten by these ticks may develop a reaction to certain foods. This reaction can be triggered by eating red meat or other products. The ticks pick up a molecule from animals they previously fed on, which can then be passed to humans.

Further information on this issue is available from the Centers for Disease Control and Prevention, which published the research findings.
