Failure to meet quality criteria may compromise bird performance, which could make the feed ‘unfit for purpose’.
Hazards are typically classified as physical, chemical and biological.
Biological hazards in- clude microbiological contaminants such as mould and salmonella.
farm biosecurity and hy- giene measures are need- ed to control salmonella infections, with feed and feed mill hygiene aimed at keeping the feed free of the bacteria.

- Ensure a delivery truck hygiene program is in place (the use of dedicated vehicles is an advantage)
- Have systems in place to prevent wild bird entry, such as in the intake pit area and out-loading area entry and exit doors (mesh bird netting use where practical); and
Controlling feed safety risks may entail hazard prevention, elimination or reduction.
Salmonella is a notori- ous biological hazard due to its potential to contami- nate food products.

A key element of feed ‘safety’ is to produce feed that is microbiologically safe, and so the basic premise of a feed mill sal- monella control program is to produce feed that is free of all salmonellae.

ture, storage and distribu- tion of the feed to ensure safety for the animals consuming the feed, and of course safety for people consuming food products derived from the birds.
Salmonella can be ingest- ed by the bird, multiply in the gut and then spread and persist in the environment, thus becoming a source for other birds.
Feed mill surveys have been published showing the percentage of samples detected with salmonella from various points along the feed production pro-

- Finished feed testing schedule for salmonella and total Enterobacte- riaceae.
3. Have procedures in place to kill the bacteria.
• Feed delivery trans- port:
Examples of some items that require consideration in a feed mill’s salmonella control program include (see Kemin’s ‘Feedmill Salmonella Control Pro- gramme’ booklet for de- tailed preventative meas- ures and preventative ac- tions, monitoring actions, corrective actions and records):
- Routine truck cleaning including inhibitor prod- uct powder fogging treat- ment; and
• Feed ingredient sup- pliers:
- Immediately remove spilt feed and feed ingre- dients from all locations in and around the feed mill;
- Establish and maintain an approved supplier sys- tem;
- Cover intake pits when not in use;
- Approved suppliers should ideally have an audited quality manage- ment system that includes monitoring and control- ling salmonella; and
- Extensive, controlled and managed use of bait stations for rodents;
• Feed ingredient re- ceival:
- Exclude domestic and wild animals.
Key message
- Establish a sampling and total enterobacte- riaceae count/salmonella testing schedule;
A low level of participa- tion in feed mill and feed hygiene is associated with higher salmonella risks.
- Salmonella inhibitor powder (Sal CURB) flush treatments for ingredient intake pits and augers; and
Increasing levels of par- ticipation and intervention are associated with pro- gressively reduced risk.
- Powder fog ingredi- ent storage bins and flat storage areas with powder inhibitor.
While interventions can be ratcheted up or down, the ‘default’ level of par- ticipation and intervention options need to be deter- mined by analysing and assessing the risk of the salmonella hazard in rela- tion to any adverse effects and consequences.
• Treat high-risk feed ingredients with a liquid salmonella inhibitor prod- uct (Sal CURB):
- When used in critical diets;
- Routine treatment or as required based on testing and/or prior contamina- tion history;
Appropriate preventa- tive and corrective meas- ures and actions are re- quired to control salmo- nella in feed and in the feed mill environment.
- May require designat- ed storage bins.
• Mixer and pellet press:
- Mixer cleaning regime – removal of accumulated material and inhibitor product treatment;
- Use of dedicated ve- hicles.
• Feed mill pest control program:
- Grounds around mill to be well drained;
- No long grass in or around the mill site;
