Question: Please list the full names of the sanitarians who did at least one inspection in May, 2010.
Evidence: full name refers to first_name, last_name; in May 2010 refers to inspection_date like '2010-05%'; sanitarian refers to title = 'Sanitarian'

SQL:
SELECT DISTINCT T1.first_name, T1.last_name FROM employee AS T1 INNER JOIN inspection AS T2 ON T1.employee_id = T2.employee_id WHERE strftime('%Y-%m', T2.inspection_date) = '2010-05' AND T1.title = 'Sanitarian'
