§ 1.90. Anthrax.
(a) Any livestock found on antemortem inspection to be affected with anthrax shall be identified as ‘‘Pa. Condemned’’ and disposed of accordingly.
(b) No other livestock of a lot in which anthrax is found on antemortem inspection shall be slaughtered and presented for postmortem inspection until it has been determined by a careful antemortem inspection that no anthrax infected livestock remains in the lot.
(c) Apparently healthy livestock (other than hogs) from a lot in which anthrax is detected, and any apparently healthy livestock which have been treated with anthrax biologicals which do not contain living anthrax organisms, may be slaughtered and presented for postmortem inspection if they have been held not less than 21 days following the last treatment or the last death of any livestock in the lot. Alternatively, if desired, all apparently healthy livestock of the lot may be segregated and held for treatment by a Commonwealth licensed veterinarian under supervision of a program employe or other official designated by the veterinary supervisor. No anthrax vaccine (live organisms) shall be used on the premises of an official establishment.
(d) Livestock which have been injected with anthrax vaccines (live organisms) within 6 weeks, and those bearing evidence of reaction to the treatment, such as inflammation, tumefaction or edema at the site of the injection, shall be condemned on antemortem inspection, or such animals may be held under supervision of a program employe or other official designated by the veterinary supervisor until the expiration of the six week period and the disappearance of any evidence of reaction to the treatment.
(e) When livestock are found on antemortem inspection to be affected with anthrax, all exposed livestock pens and driveways of the official establishment shall be cleaned and disinfected by promptly and thoroughly removing and burning all straw, litter and manure. This shall be followed immediately by a thorough disinfection of the exposed premises by soaking the ground, fences, gates and all exposed material with a 5% solution of sodium hydroxide or commercial lye prepared as outlined in § 1.121 (relating to cleaning of equipment contaminated with anthrax) or other disinfectant that may be approved in specific cases by the Department specifically for this purpose.
