The FDA mesh size to control foreign body contamination is 7mm.

Is anyone aware of the standard in the UK?

 

Thanks

Hi, HACCPCOR.

 

AFAIK, size is "not defined" in UK standards but, mentioned in general is to control physical hazard. Also, I think, what CANADA have is stricter (2mm) relative to any regulations in terms of physical hazard limit.
