Honey Hygiene Flashcards
Describe the organisation and structure of honey production.
Queen (lays eggs)
Drones (males, mate with queens)
Workers (female, do everything else)
Understand the compositional characteristics of honey, their pharmacological properties and how these relate to the uses of honey.
- Low water activity(aw) restricts microbial growth
- H2O2 in some honey
- Hundreds of bioactive compounds which have overlapping spectra of antimicrobial action
Describe the main microbiological and pharmacological residue issues associated with honey
- May contain viable Cl. botulinum - do not feed honey to children under 12m as immature gut microflora cannot comepete
- Risk of pesticide residues - organophosphates , organochlorines
Give 4 notifiable diseases of bees
European Foul Brood
American Foul Brood
Tropilaeplaps
Small hive beetle
Describe the lifecycle of a honey bee
- Egg laid in hexagonal wax cell and hatch into larvae
- Workers cap cells when larvae ready to pupate
Describe the difference in cells of the three be categories
Queen - large hangs off edge
Drone - domed cap
Worker - Flat cap
Describe the difference in cells of the three bee categories
Queen - large hangs off edge
Drone - domed cap
Worker - Flat cap
Describe the process of honey bee feeding
Nectar:
Mainly sucrose.
Invertase converts sucrose to glucose and fructose.
Nectar regurgitated into storage cells.
Pollen collected in ‘baskets’ and packed down into cells by worker ‘house’ bees.
Describe the honey extraction process
Take a knife, scrape off the honey cappings and place into a centrifugal extractor
Can eat the wax as well as the honey
What percentage water should honey have to reduce fermentation issues ?
20%
What percentage water should honey have to reduce fermentation issues ?
20%
Describe European Foulbrood in bees
M.plutonius
Brood exhibits shotgun pattern
Dead larvae, brown tan comour and melted appearance
(healthy larvae should be c shaped and pearl coloured)
Describe American Foulbrood in bees
Paenibacillus larvae
- Brood die after being capped
- Ropiness test - melting of larvae results in them becoming string like
Descroy colony and burn equipment
Describe the Tropilaelaps mite in bees
Parasitic mites affecting both developing brood and adult honey bees
Can cause abnormal brood development and death of both brood and bees
Descrive the small hive beetle in bees
A.tumida
Larvae eat wax, pollen, honey, bee brood, and eggs
Contaminate honey causing fermentation
Good husbandry effective defence
