Final answer:
Transformation is not covered as one of the four main pillars of food security; those are availability, access, utilization, and stability. The US Food Code does cover effective employee training.
Step-by-step explanation:
In addressing the question regarding the US Food Code, it's essential to clarify that the effective employee training is indeed covered within this comprehensive set of regulations. However, when discussing the pillars of food security, we find that while availability, access, utilization, and stability are acknowledged as essential components, the term 'transformation' is not recognized as one of the main pillars of food security. Food security is built upon the premise that all people at all times have physical, social, and economic access to sufficient, safe, and nutritious food which meets their dietary needs and food preferences for an active and healthy life.
It is clear that Transformation is the option that is not covered as one of the pillars of food security according to the information provided above. Food security is fundamental to public health and the US Food Code is an integral part of ensuring food safety standards are met, including proper employee training to prevent foodborne illnesses.
