(b)determining whether there is evidence of antimicrobial resistance in any such zoonotic agent or in any other agent that presents a threat to public health;
(c)determining, if the epidemiological situation so requires, whether—
(i)any other zoonosis or zoonotic agent exists or has existed there,
(ii)there is evidence of antimicrobial resistance in any such zoonotic agent,
(iii)any agent of any infection that exists or has existed on those premises is transmissible directly or indirectly from animals to humans, or

(3) If a justice of the peace, on sworn information in writing, is satisfied that there are reasonable grounds for entry into any premises for the purposes of the enforcement of these Regulations and—
