Withdrawal Period

The time required for a drug or hormone to pass through an animal's system before slaughter.

Beta-agonists

Synthetic chemicals that shift nutrients away from fat production to promote lean muscle growth.

ractopamine hydrochloride

A type of beta-agonist allowed in the US.

zilpaterol hydrochloride

Another type of beta-agonist allowed in the US.

Antibiotics

Used to prevent and treat illness in livestock animals.

Sub-therapeutic use of antibiotics

Administered in small, preventative doses through feed and water.

FDA Approval

Antibiotics must be approved for their intended use before being administered to livestock.

FSIS Monitoring

The Food Safety and Inspection Service monitors withdrawal periods through testing.

Safety Second

FSIS collects samples from meat products to test for hormone and antibiotic residues.

Importance of Reading Labels

Vital to read drug labels to understand withdrawal periods and delays in harvest.

Influence of Handling Procedures

May affect red meat yield due to bruising and overall meat quality.

Reducing Injury and Stress

Handling procedures should aim to prevent injury and stress to livestock.

Shipping Horned Cattle

Should not be shipped in confined spaces to prevent bruising.

Use of Sorting Sticks

Properly used to prevent bruising and lesions in livestock.

Designing Facilities

Should minimize stress and injury during handling.

Short-term Stress in Swine

Should be avoided immediately prior to slaughter to prevent meat quality issues.

Long-term Stress in Livestock

Must be prevented to avoid degradation of meat quality.

Antibiotic Residues Testing

FSIS tests meat products to detect residues of antibiotics.

Preventive Doses

Small doses of antibiotics administered to livestock to prevent illness.

Larger Doses of Antibiotics

Administered to treat illness in livestock.

Withdrawal Period Monitoring

FDA sets and FSIS monitors the withdrawal periods for livestock drugs.

Bruising Prevention

Proper handling can prevent bruising in red meat.

Animal Stress,

Stress can negatively impact meat quality.

Healthy Livestock Supply

Use of antibiotics helps maintain a steady meat supply from healthy animals.

Testing Samples

FSIS collects about 1.5 million samples per year for residue testing.

Administering Antibiotics

Must follow FDA guidelines and ensure appropriate timing related to harvest.
