FOOD SAFETY • THE PRACTICAL CERTAINTY THAT • INJURY OR DAMAGE WILL NOT • RESULT FROM A FOOD OR • INGREDIENT USED IN A REASONABLE MANNER OR QUANTITY
SAFE FOOD WHOLESOME MEAT A PRODUCT THAT IS NUTRITIOUS WITH MINIMAL MICROBIAL CONTAMINATION, NO CHEMICAL RESIDUES ABOVE ACCEPTABLE LIMITS, NO PARASITES AND WHEN PREPARED PROPERLY IS BENEFICIAL TO HUMAN HEALTH WHEN CONSUMED.

FACTORS CONTRIBUTING TO FOODBORNE DISEASE • 12 % Food from unsafe sources • 63% Improper STORAGE temperature • 28% Poor personal hygiene • 23% Contaminated equipment • 21% Inadequate cooking • 20% Other things
Biological Chemical Physical Types of Food Contamination
Bacterial Growth • A single bacterium at 10am today has a doubling time of 20 minutes • By 8pm, there will be 1,000,000,000 • Bacteria have not taken over the planet because growth is limited at about one billion per gram or ml due to: • Using up of all nutrients • End product poisoning • Limit of space
Food-borne Illness Causing Microorganisms • Staphylococcus aureus • Salmonella species • Clostridium perfringers • Clostridium botulinum • Campylobacter jejuni • Listera monocytogenes • Yersinia enterocolitica • Escherichia coli (0155-H7)
PHYSICAL CONTAMINATION • One of the major concerns in producing meat animals. • Handling • Treating • Feeding • Transporting
PHYSICAL PROBLEMS Bruising Injection site problems Stress Contamination
PHYSICAL CONTAMINATION • One of major concerns to the animal producer
Chemical Contaminants • Intentional Food Additives • Use of materials which enhance the acceptability of the products and/or aid in the development of the product • Unintentional Food Additives
Chemical Contaminants Con’t • Residues • This includes both food processing component residues as well as PESTICIDES, ANTIBIOTIC OR HORMONE IMPLANT residues • Natural Toxicants • Product Tampering • Nutritional Components
NATURAL BEEF PROGRAMS No antibiotics No growth promotants No hormone implants Details of production
NATURAL BEEF, CONTINUED Packer must certify: • That animals are harvested at the beginning of the shift • Identified as natural beef in the storage cooler • Processed minimally at the beginning of the processing shift • Labeled as natural
The Food Safety and Inspection National Residue (Monitoring) Program • In 1992, illegal levels of pesticides, • hormones, antibiotics, drug and • other chemical residues occurred • in 0.29% of more than 43,000 • livestock/poultry samples tested
Pay-Lean • Recommended use 4.5 to 9 grams per ton • Problem comes from top dressing over use
SELECTING YOUR 4H/FFA HOG • Try to select from boars that are free of the stress gene. • This will assure that you will eliminate the PSS problem
EATING QUALITY PROBLEMS • Meat is less tender • Lacks flavor • May have an off flavor
Bruises • Problem in sheep and cattle
Blood Splashing • Capillary rupture In cattle, sheep, swine Increased incidence
