Presentation on theme: "FEED ADDITIVE & HORMONE IMPLANT REGULATIONS Animal Science II Unit 3."— Presentation transcript:


2 Regulation of the Use of Additives  Regulated by the Federal Food and Drug Administration (FDA)  Regulations change from time to time as new information on effects and changes becomes available  Current detailed information may be found in the Feed Additive Compendium  This is published annually

3 Regulation of the Use of Additives*  Code of Federal Regulations (CFR) Title 21 contains official information from the FDA concerning approval of antibiotics and other animal drugs  Revisions are made annually as of April 1 and the CFR is updated in individual issues of the Federal Register  The CFR and Federal Register must be used together to determine the most current regulations concerning animal drugs

4 Label Requirements  Any feed that contains one or more drugs is defined as a medicated feed  May be complete feed mixes or pre-mixes that are mixed with other feeds  FDA requires all manufacturers of medicated feeds to provide information on the label relating to the use of the feed

5 Label Requirements  “Medicated” must appear under the name of the feed  S pecific purpose of the drug or drugs must be on the label  N ame and amounts of all active drugs must be listed  R equired withdrawl period prior to slaughter must be given  Cautions against misuse must be listed  Directions for the use  Lot or control number for later identification  Medicated feeds that are mixed at the local feed mill must meet the same requirements

6 Mixing and Residue Avoidance  Proper mixing is important for safe use  Drug residues can cause financial losses  A regular procedure should be followed when mixing medicated feeds to avoid problems and drug carryover  P. 157-8

7 Keeping Records  Recommended records  Date the batch was mixed  Mixing order and amount of medication added  Mixing time  Storage location  Number, age, weight of animals fed from the batch and amount given per head  Medication that was used, amount, concentration in the batch  Date of cleaning mixers, bins, conveyors, feeders

8 Keeping Records  Have a long term plan for the use of the feed additives  Periodically changing the type of antibiotic used  Reduces the chance of the microorganisms building immunity  Should be made about once a year  Do not make frequent changes

9 Health Concerns  Growing concern that the continued use of antibiotics in animal agriculture will have an adverse effect on humans as well as animals  Centers around the use of antibiotics at subtherapeutic levels  feared that this continued use will lead to the development of resistant strains of microorganisms  Bacterial resistance to drugs has been observed almost from the time antibiotics were first used in animal feeding

10 Economic Impact  I ncreased cost of animal products to the consumer  L ess meat and livestock produced  C ost of production would be higher  More feed would be required per animal and decreased rate of gain  Death loss

11 No Evidence*  To date no persuasive evidence of animal or human health problems arising from nearly 30 years of using antibiotics in animal feeding  Many of the same antibiotics used today are the same as the ones that were used when antibiotic feeding began and they are still effective against most microorganisms  Critical experimental study is needed on the effect of low-level antibiotic feeding on animal and human health

12 Cancer Causing Effects  FDA has expressed concern  1958 Food Additives Amendments to the Food, Drug, and Cosmetic Act of 1938 include prohibitions against adding to food any substance that is a know carcinogen  Ongoing research into the possible carcinogenic effects of feed additives  If effects are found in any additive, it’s withdrawn from use
