These Regulations amend the Food Hygiene Regulations 2009 by introducing a definition for "low-acid canned food", mandating specialized food safety training and certification for personnel involved in low-acid canned food manufacturing and mass catering supervision, requiring non-absorbent surfaces and connections to the sewerage system in food premises, and removing compulsory medical examination references for food handlers while establishing penal provisions for non-compliance with mass catering training requirements.
