Is serving deities at our place in nuclear families by ladies during 4 days of menstruation allowed in ISKCON?

Question from Kamlesh Khurana –

Prabhupada quote:

According to the smarta vidhi, women cannot touch deity during menstrual period but the goswami viddhi allows. But it is better not to do it. One thing is that the seva can never be stopped for any reason. This also for the cooking.
