Fertilizer getting stuck under one's shoes

Q:

1. I live in a complex and the gardeners have over the weekend put fertilizer on the grass. I am not sure what fertiliser it is but I do know that some fertilisers contain animal faeces. With everyone walking all over the complex the fertiliser is now on the floor on many of the passages and common areas. I have tried my best not to walk on it but am not certain if I have been successful. Please can you let me know the following:

a. If I have stepped on it does it make my shoes and everywhere I subsequently walked (e.g. in my home and car) napaak?
b. Can my kids still paly and walk on the grass, given that the fertiliser has been put on or will it make their shoes and clothes napaak?

2. I sometimes leak urine, therefore I wear a sanitary pad so not to make my clothes napaak, when I sit somewhere for a long period of time or sleep, I perspire. I am therefore concerned that given that urine is on the sanitary pad when I perspire between my legs this is making my bedding or the chair that I am sitting on napaak. Please can you let me know if this in fact the case and whether I have to clean these items every time this happens?
