We've written about fish pedicures a lot on Kiss and Makeup since we first saw them back in 2008, so we were slightly alarmed to see them all over the newspapers this morning after it was revealed that the treatment could spread infections like HIV and Hepatitus C.
Basically, if a user infected with a blood-borne virus bleeds into the water, there is a chance that the infection can be passed on - don't panic if you've had one: the risk is low, although according to the Health Protection Agency, 'can't be completely excluded' and people with diabetes, psoriasis or a weak immune system are 'particularly vulnerable' and should completely steer clear.
An agency spokesman said: "We have issued this guidance because there are a growing number of these spas."
"When the correct hygiene procedures are followed, the risk of infection is very low," they added. "However, there is still a risk of transmission of a number of infections - this does include viruses like HIV and hepatitis."
