Also feed insects are ultimately human food

13
Starting point is always feed grade material
What is feed grade material?In essence everything allowed by (EU) law to feed to animals
law
However additional required: Quality schemes
14
Some examples of feed grade material
• Grains• Seeds• Meals from oil crushing, fats & oils• By products from food industry• Currently supermarket returns guaranteed without meat
15
Examples of not feed grade materials
Household waste Restaurant left overs
Manure
Supermarket residues containing animal protein?
16
What are important topics for feed safety?
• Uncontrolled substances
• Heavy metals
• Mycotoxins
• Pathogens
• Insecticides and herbicides
17
Heavy metals
What is accumulation?

Unwanted increase of heavy metal in the insect

So what are the implications of this?
• Depending on the insect specie used starting material has to have lower level of certain heavy metals as maximum allowed level in feed
• Strict quality control needed on heavy metal concentration of feed material and insect produced
And the opportunity:
For example yellow meal worm on high lead (Pb) feedstocks
23
What are mycotoxins?
Mycotoxins are poisonous chemical compounds produced by certain fungi
Source FAO
Mycotoxin Commodity
deoxynivalenol/nivalenol wheat, maize, barleyzearalenone maize, wheat
ochratoxin A barley, wheat, and other commodities
fumonisin B1 maize
aflatoxin B1, B2 maize, peanuts, and other commodities
aflatoxin B1, B2, G1, G2 maize, peanuts
24
Mycotoxins
• Are harmful to animals and humans• Some are transmitted via the animal to humans• Legal limits on amount in feed stocks• Lower limits for younger animals and humans• Industry uses even lower levels for optimal performance• Will be present in feedstock for insects
How are the insects reacting to mycotoxins?
25
Mycotoxins experiment
• Black soldier fly and lesser meal worm
• Aflatoxin B1, deoxynivalenol (DON), ochratoxin A or zearalenone
and as a mixture of 4 mycotoxins
• 1, 10 and 25 x the legal limit in the feed
Toxins 2018,10, in press
26
Mycotoxins experiment
• No effect on growth or survival of BSF and LMW
• No difference between single or mixture of the 4 mycotoxins
• None of the mycotoxins accumulate in the larvae
• Both BSF and LMW metabolize (break down) the mycotoxins
• Very low level of metabolites are present with the exception of ZEA
metabolites in BSF.
Toxins 2018,10, in press
27
So what are the implications of this?
• Using lightly contaminated feedstocks with levels upto the legal limit in feed for mycotoxins are safe.
• ZEA and BSF needs to be investigated further
And the opportunity:Higher legal limits for mycotoxins in feedstuffs for insects
(needs additional research)
28
What are important topics for feed safety?
• Uncontrolled substances
• Heavy metals
• Mycotoxins
• Pathogens
• Insecticides and herbicides
29
Pathogens
• Harm full bacteria as Salmonella, E. Coli, Campylobacter
• Important to control in every step of the food chain
• how sensitive are insects to these pathogens?
Research question:do these pathogens grow well in these insects or not?
Still be answered
30
Insecticides and herbicides
• Can be present in low amounts in feed (i.e. grains)
• How sensitive is the production insect to these insecticides?
– Does it grow slower or not?
• Do these insecticides accumulate in the production insect?
Research questions:
Still be answered
31
Summary Feed Safety
• Starting point is always feed grade material – no waste!
• Heavy metals need attention
• Mycotoxins are an opportunity
• Pathogens and insecticides still to be investigated

What is needed for cost effective production
The same elements as in other animal production
Optimal feed
Optimal housing and management
Optimal genetic

All still open questions
Plus for exampleOptima particle size of the feed?Do the insects eat selectively?……
38
Housing
• Most still very small scale
• In house pioneering (trial and error) within startups / insect breeders
• In traditional animal production we saw specialization in different
companies. Besides the farmer: housing, breeding, and feed
companies
• How will the insect market develop? similar or more as all in one?

Genetic improvements

The first steps are being made

And also
Own in house selection by various producers
40
Main take home messages
• Animal feed market is 1 billion tons
• Starting point is always feed grade material
• Heavy metals are an attention point
• Mycotoxins an opportunity
• Feed, Housing, and Genetics key for economy
• A lot of research questions still open
• Will specialization occur also with insects production?
