In Summary

  1. Heat can be used as a control against surfaces or niches that are suspected of harbouring L. monocytogenes. Especially in older equipment which are difficult to disassemble. 
  2. For small pieces of equipment, submersion in a hot (>80°C) water bath with detergent will likely be effective. Larger equipment which is water sensitive may be heat treated in an oven. 
  3. For equipment which is too large for an oven, a treatment may be to cover with a tarpaulin, protect/remove any electronic components, and treating with steam. 
  4. Alternatives may be to treat with ozone or UV-C, although their effectiveness will need to be validated by surface material.
