Hi Everyone,


I want to know what is the government regulation (CFIA and FDA) on the magnet strength? It seems that I couldn't find any related information.

You won't from CFIA, as of January 15 2019 the new regulations come into effect and they are less prescriptive than currently (so you can do it your way as long as it's safe) so this is all they have to guide you





  • The strength and type of magnets are appropriate to the use.
  • Magnets are installed in a manner to effectively remove ferrous metal prior to, or after, certain operations (e.g.dicing, slicing or filling).
  • The strength of magnets is confirmed with the use of probes or other effective devices as necessary.
  • Magnets are monitored as necessary to ensure effective operation and surface exposure (e.g. adequately cleaned, metal particles removed).

The FDA slightly less

Effective measures shall be taken to protect against the inclusion of metal or other extraneous material in food. Compliance with this requirement may be accomplished by using sieves, traps, magnets, electronic metal detectors, or other suitable effective means.



Your best course of action is to speak with a tech at the company supplying the magnet to ensure it's capable of what you deem safe.......you could perhaps use the particle size as a basis for determine magnet strength?



Please stop referring to me as Sir/sirs

Dear all,


I agree. The strength is not the only paarmeter. There are many factors influencing the efficiency of a magnet.  There the strength has to br appropriate for the application. The has to be demonstrated and controlled.

e.g. Neodyn is temperature and shock sensitive.
