Lecture 28 10/22/24 Flashcards
What are the common sources of residues in meat products?
-drugs
-chemicals
Why are residues important?
-allergies
-antimicrobial resistance
-unknown safety issues
What role does the FDA serve in handling drug residues?
sets tolerances for acceptable levels of residues of drugs in animal tissues
What role does the EPA serve in handling drug residues?
approves pesticides for use on animals
What are the roles of USDA FSIS in handling drug residues?
-monitors tissue samples for veterinary drugs, pesticides, and environmental contaminants
-takes enforcement action on adulterated products/animals with residues above tolerance levels
What are the characteristics of the US NRP for Meat, Poultry, and Egg Products?
-interagency program designed to identify, rank, and test chemical contaminants
-prevents distribution of adulterated and misbranded food
What are the characteristics of the FSIS monitoring program?
-all animals slaughtered at federally inspected plants have potential to be sampled
-3 or more individual tissue samples taken from a single animal
-each sample analyzed for one or more compounds
What are the steps of inspector generated sampling?
-carcass is identified
-in-plant screening occurs
-positive samples are sent to FSIS lab for further testing
-negative samples are released for human consumption
Which tests are considered in-plant/on-farm tests?
-fast antimicrobial screen test
-kidney inhibition swab test
What are the characteristics of the live animal swab test?
-involves testing animal urine
-supplies include sterile cotton swabs, test plate, and incubator
-practical for residue avoidance
-can test live animals for illegal residues before they go to market
What are the characteristics of the sulfa-on-site test?
-screen swine serum, urine, and feed for sulfamethazine and other sulfonamides
-screen large numbers of swine for residues at slaughter establishment
-farm-based pre-slaughter program also being developed
What is the goal of the FSIS monitoring program?
to sample each species at a rate that will detect 1% incidence with an assurance of 99%
Why does FSIS test animals from subsequent flocks/herds?
to assure that residues from each particular farm remain below legally permissible levels
What happens if FSIS finds illegal residues?
-special surveillance programs with increased testing are established
-drug residues are reported to FDA
-pesticide violations are reported to EPA
What are the consequences of illegal drug residues from the FDA?
-seize or condemn food intended for humans
-seize animal feed
-criminal charges for repeat offenders
