- Sulfa-containing veterinary drug products can be
administered orally or through injection, feed or water.
- Some sulfa products are not destroyed by rendering –
leading to a build up of drug residues in MBM. Contaminated
MBM fed back to livestock can result in sulfa residues in food
products.
- Livestock mortalities with sulfa residues must not enter
the rendering process.
- Regulatory agencies monitor residue levels for sulfas and
other drugs in MBM, meat, milk and eggs.
- Violations put the deadstock collection system at risk.
For a list of all sulfa medications, contact your
veterinarian or visit OMAFRA’s Web site at
http://www.gov.on.ca/OMAFRA/english/livestock/ceptor/2002/sept02a5.htm
Label directions apply to both deadstock and livestock.
- Follow all label directions for species of use, route of
administration, dose and withdrawal times.
- Keep accurate drug use records and identify treated
livestock.
- Ignoring label directions leads to residue levels and
threatens the future of deadstock collection.
Your deadstock collector is being asked by rendering firms to
provide sulfa-free certification on all materials delivered for
rendering.
- Producers are encouraged to sign the certification letter
available from deadstock collectors.
- Clearly identify and segregate livestock mortalities that
are not eligible for collection.
Your on-farm options are:
Discuss all sulfa product use with your veterinarian.
Consider if other options are available.
- Livestock mortalities which may contain sulfa residues
must be disposed of either by burial under at least 2 ft of
soil or by composting.
- Composting resources are available on OMAFRA’s Web site.
