Reconsideration of Approvals and Registrations
Related to Carbon Disulfide

The APVMA, in accordance with Part 2, Division 4, of the Agvet Codes, has completed its reconsideration of the registrations of all products containing carbon disulfide and the approvals of all associated product labels listed below.

PRODUCT NO.	PRODUCT NAME	LABEL APPROVAL NO.
41130	C.S.S.P Phosphorus Pig Poison	41130/0802

Carbon disulfide (CS2) is used for the control of feral pigs and is administered through lacing a bait carcass (sheep, kangaroo, cattle, goat, pig) with the poison. The product is registered for use in Queensland and the Northern Territory and is used in New South Wales under permit. The pig poison was reviewed due to possible toxicological effects related to CS2 and concerns that labels did not contain adequate instructions in relation to the safe handling of the product and first aid in the event of an accident caused by the handling of the product.

Following the finalisation of its reconsideration, the APVMA was not satisfied that the label approvals listed in the table above:
· complied with the prescribed requirements under paragraph 14(3)(d) of the Agvet Code; and
· contained adequate instructions relating to the matters referred to in paragraph 14(3)(g) of the Agvet Code.

However, the APVMA was satisfied that label approvals could be varied in such a way that the APVMA is satisfied. Accordingly, the APVMA after satisfying s.34(5A) and s.35(5B) has varied the relevant particulars of label approval to include the following instructions:

Directions for use
Distribute approximately 60g of the product evenly through chest cavity, stomach and slits in meat of bait carcass.

MINIMUM DISTANCE RESTRICTIONS FOR LAYING CSSP PHOSPHORUS PIG POISON BAITS.
1. Property Boundary: No bait shall be laid within 5 metres from any property boundary.
2. Habitation (means the dwelling or other place where any person, other than of the owner/occupier carrying out the baiting lives): No bait shall be laid within 500 metres of a habitation.
3. Domestic water supply (means the water line or small dams from which water is pumped or the draw off point from wells, bores, etc): No bait shall be laid within 100 metres of a domestic water supply.
4. Public roads: No bait shall be laid within 200 metres of a public road.

EXCLUDED AREAS- WHERE CSSP PHOSPHOROUS PIG POISON BAITS MAY NOT BE LAID.
CSSP Phosphorous Pig Poison baits must not be laid in areas where distance restrictions cannot be met.

Public notification
Before laying baits at least 3 days notice must be given to anyone whose property boundaries fall within 4 kilometres of the outer most baiting line on the property which is to be baited. Notification can be given by telephone or personal contact, or, where this is not possible by mail, or by public notice in a local newspaper.

Notices
The landholder must put up notices immediately before laying CSSP Phosphorous Pig Poison or poisoned bait material on the property. These notices must remain up for at least 4 weeks, and must be placed:
1. At every entry to the property;
2. At the entrance to the actual poisoning site;
3. At the extremities of property boundaries where the property is a public thoroughfare; and
4. At all bait stations.
The notices may be obtained from the Rural Lands Protection Boards and must specify that pigs are being poisoned, and the date of poisoning.

Bait material
CSSP can only be used on carcasses of sheep, cattle, pigs, goats and kangaroos.

When to poison
It is often difficult to get feral pigs to find or take baits when there is abundant green feed. The best time to poison is when grasses and other herbage are dry and pigs are hungry.

Bait placement
Feral pigs almost always follow pads (trails). Carcasses should be placed near major pads, particularly near watering points. A trail of grain can be used to draw pigs onto the bait. Grain that has been soaking in water for several days is often effective. If grain is to be used as the attractant, stock will have to be moved from the paddock to be poisoned. Clear any flammable material from within 3m of the bait to reduce fire risk.

Bait and carcass recovery
To the extent possible, animal carcasses must be recovered during and for 14 days after a baiting campaign and be destroyed by burning or burial according to the requirements of the State or Territory in which use has occurred.

Any incidents where it is suspected that non-target animals may have been poisoned by C.S.S.P Phosphorus Pig Poison, must be notified to State authorities.

Risk to domestic dogs
Take care to avoid accidental poisoning of domestic pets, particularly in closer settled farming areas. It is advisable to tie up or muzzle dogs during poisoning operations.

Safety directions
Very dangerous. Poisonous if swallowed. Will damage the eyes and skin. May irritate the nose and throat. Avoid contact with eyes and skin and clothing. Do not inhale vapour. Open container in the open air. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. When opening the container and using the product, wear cotton overall buttoned to the neck and wrist or equivalent clothing, elbow-length PVC gloves, chemical resistant footwear and (if indoor) half facepiece respirator. After each day’s use wash gloves and contaminated clothing. Do not re-use footwear until thoroughly aired.

First aid
If poisoning occurs, contact a doctor or Poisons Information Centre. Phone Australia 131126. If poisoning occurs get to a doctor or hospital quickly. If swallowed, do NOT induce vomiting. Give a glass of water. If skin contact occurs, remove contaminated clothing and wash skin thoroughly. Remove from contaminated area. Apply artificial respiration if not breathing. If in eyes, hold eyes open, flood with water for at least 15 minutes and see a doctor.

The APVMA is now satisfied that provided that the conditions to which the registration is currently subject are complied with, the continued use of, or any other dealing with the product in accordance with the instructions for its use:
· would not be an undue hazard to the safety of people exposed to it during its handling; and
· would not be likely to have an effect that is harmful to human beings.

On this basis the registration of the product C.S.S.P Phosphorus Pig Poison (41130) has been affirmed.
