Make hygiene number one
CLEANING is a vital component for poul- try farmers in the biosecurity battle to protect their birds and livestock.
Aussie Pumps is arm- ing producers with the right tools for this very important task.
Aussie Pumps is Aus- tralia’s leading pro- ducer of high-pressure water blasters.
The company has de- veloped a range of hot water steam cleaners for fast decontamina- tion and hygienic clean- ing.
Using Aussie’s steam pressure cleaners de- creases cleaning time by up to 40 percent and cleaning with hot wa- ter reduces the drying time.
These machines are designed particularly with primary producers in mind.
The Aussie Super In- dy range includes single and three-phase steam- ers with pressures as high as 4000 psi.
Aussie Pumps’ Super Indy series are built tough, featuring heavy- duty impact-resistant stainless steel covers.
The cover is mounted on a robust steel chassis with integrated front- mounted bumper.
Aussie Pumps product manager Mal Patel said, “We decided to move away from European- style machines with their traditional poly or
plastic components.” “The machines are loaded with features to make them easy and safe to use but provide plenty of capability for fast and effective clean-
ing and sanitising.” The option of high- pressure detergent in- jection adds another
level of efficiency.
The pumps are a heavy-duty Italian tri- plex design running at 1450rpm for long and continuous trouble-free
life.
The range starts with
a 240V single-phase machine delivering 1500psi and 12l/pm flow.
This machine reaches 120C, providing loads of steam power.
Three-phase machines are also available in a powerful 3000psi con- figuration with big flows of 19l/pm.
“We developed a
3000psi unit with the ability to ‘wash and flush’, delivering high flow and pressure,” Pa- tel said.
“This lifts productiv- ity and reduces down time.”
The mild steel burner coils are covered by a free extended warranty of up to two years.
A stainless steel burn- er coil option comes with a three-year war- ranty.
The new Aussie Super Indy range offers timed ‘Total Stop’ designed to shut the machine off af- ter the operator releases the trigger of the gun.
This not only reduces wear on the machine but saves power.

The Aussie Pumps Super Indy steam cleaner is used for equipment decontamination in the bio- security war.
Salmonella – the notorious biological hazard
☛ from P10 The farm
Apart from feed, there are many potential sal- monella entry points onto the farm including drink- ing water, litter, day-old chicks, replacement pul- lets, trucks, pests, wild birds, other livestock and domestic animals, equip- ment and people.
Pest control, biosecurity, farm and personal hy- giene, egg washing and vaccination are compo- nents of on-farm control.
A range of feed additives are also being explored to assist in managing the salmonella hazard in egg-laying hens and meat birds.
Example one
When seven-day-old broiler chickens were heavily infected with a field strain of salmo- nella enteritidis (orally inoculated with one million colony units), a coated/‘protected’ formu- lation of seven essential oils and two organic acids
included in the feed at 1kg or 2kg/tonne resulted in significant reductions in S. enteritidis counts in the caecum at seven and 14 days after infection (Fig- ure 2).
Reductions in the faecal counts were recorded at three, five, 10 and 12 days after infection (Figures 3 and 4).
This work was conduct- ed at the ‘Istituto Zoo- profilattico Sperimen- tale della Lombardia e dell’Emilia Romagna’ in Italy.
In a similar trial with broiler chickens orally infected with S. enter- itidis at 11 days of age, the same coated product included in feed at 750g and 1kg/tonne significant- ly reduced the number of birds with caecal samples positive for salmonella (P<0.05) and with salmo- nella positive neck skin samples (P<0.01) at day 40 (Table 2).
This work was con- ducted at the ‘Centro de Investigacion y Tecnolo-
gia Agroalimentaria de Aragon’ in Italy. Example two
When broiler chicks (50/ group) were orally infect- ed with S. enteritidis at three days of age and then sampled the next day, the birds receiving feed that contained beta-1,3-glucan from a specific micro-al- gae showed significantly reduced detection of S. enteritidis in the liver and spleen compared with sal- monella-challenged birds not receiving beta-1,3- glucan (Table 3).
A higher level (200g/ tonne) was needed to significantly reduce the percentage of birds with liver and spleen detections of S. enteritidis when the birds were challenged at seven days of age and then tested three days later compared with the chal- lenge and sampling at the younger age.
This work was carried out by the US Depart- ment of Agriculture at its College Station research facility.
Beta-1,3-glucan acts on the bird’s gut-associated immune system, facilitat- ing enhanced responsive- ness to challenges, that is, it ‘primes’ the bird to activate its own immune system.
These results indicate reduced trans-location of salmonella from the gut to the bird’s tissues when beta-1,3 glucan were in- cluded in the feed. Summary
• Salmonella is an ongo- ing biological and food safety hazard;
• Control requires mul- tiple hurdle approaches along the ‘feed to farm to food to fork’ chain;
• Control includes com- binations of prevention, reduction and elimina- tion; and
• Focus points at the ‘feed to farm’ end of the chain include:
- Feed ingredients;
- The feed mill process; - Finished feed;
- Storage and transport
of feed ingredients and finished feed; and
- The many other pos- sible salmonella entry points on to the farm.
