When the Health Author­i­ty has rea­son­able cause to sus­pect pos­si­bil­i­ty of dis­ease trans­mis­sion from any food ser­vice estab­lish­ment or retail food store employ­ee, the Health Author­i­ty shall secure a mor­bid­i­ty his­to­ry of the sus­pect­ed employ­ee, or make such oth­er inves­ti­ga­tion as may be indi­cat­ed, and take appro­pri­ate action.  The Health Author­i­ty may require any or all of the fol­low­ing mea­sures: (a) the imme­di­ate exclu­sion of the employ­ee from all food ser­vice estab­lish­ments and retail stores; (b) the imme­di­ate clo­sure of the estab­lish­ment con­cerned until, in the opin­ion of the Health Author­i­ty, no fur­ther dan­ger of dis­ease out­break exists; (c) restric­tion of the employee’s ser­vices to some area of the estab­lish­ment where there would be no dan­ger of trans­mit­ting dis­eases and (d) ade­quate med­ical and lab­o­ra­to­ry exam­i­na­tion of the employ­ee, of oth­er employ­ees, and of their body dis­charges if necessary.
