A group of Tenby sixth formers paid a visit to County Hall this week for a special lesson in environmental health.
The students from Greenhill School met Pembrokeshire County Council's senior environmental health officers, Sarah Oliver and Sarah Johns, as part of their A-Level health and social care course.
Environmental health services such as food safety, licensing, pollution, recycling schemes and pest control are a key part of the syllabus.
Sarah Oliver said the partnership between council and students had proved to be extremely successful in the past with previous students gaining excellent results.
