Su's Handbag Test
On Monday's Heart Breakfast Martin took Su's handbag off her to have some tests.
It had been reported that 33% of woman have never cleaned their handbag - Su being one of them. So, what bacteria would you actually find in her bag?
Well, Martin headed down to the Anglia Ruskin University with Su's handbag where he met up with Nicky Milner and Caray Walker from the Faculty of Science and Technology.
Take a look in the galleries below to find out exactly what they tested and what results they found.
