source of the community- acquired resistance stud- ied, however, the attribut- able non-human sources underpin the need for on- going monitoring.
Globally, antimicrobial resistance, as of April 2020, accounts for an esti- mated 2000 human deaths per week due to treatment failure.
to commonly deployed antimicrobials in poultry production in the Neth- erlands and Vietnam was shown to be more preva- lent in poultry workers than the general commu- nity.
But when people and their pets were sampled, as in a 2016 Brazil study, pet dogs were shown to be a potential household source of multi-resist- ant E. coli strains.
Intracommunity resist- ance spread alone is un- likely to be self-maintain- ing without transmission to and from non-human sources.
Countries with the high- est resistance include China, India, Mexico and South Africa.
And the data showed that specific antimicro- bial resistance was more likely to occur in family members of poultry farm workers than in the gen- eral community.
So, who is right?
Antimicrobial resistance involves us, our families, our staff, our pets and the food we produce.
Those with lower levels of resistance include, ac- cording to a US dataset released by the US-based Centre for Disease Con- trol, the US, UK and the lowest of the group, the Netherlands, which has had strong animal anti- microbial use policies in place for 20 years.
Everybody has a role to play.
This data headlined an international webinar in April led by Twan van Gerwe and Fellipe Bar- bosa, global managers for poultry and swine, togeth- er with Andreas Michels, head of biotechnology, from German company EW Nutrition.
Studies from the UK in 2019 and 2020 found E. coli causing serious hu- man infection had not originated with livestock.
Food accounted for 18.9 percent of carriage, pets 7.9 percent and farm ani- mals (non- occupational) 3.6 percent.
COVID-19 will eventu- ally be contained.
While the data drew from research in poultry, the principles can be di- rectly extended to pig pro- duction and preventative

location globally to sup- port the producer.
Stockyard technical per- sonnel are based in South Australia, Victoria and Queensland to offer on- farm practical help during the interstate travel bans.
Specialist technician Shane Daykin has been with Stockyard for over 10 years and can work though problems with older model controls over the phone.
Our people have work- ing knowledge of the con- trollers we’ve sold in the past, and of the simula- tors for the Big Dutchman controllers we’re now sup- plying.
Stockyard technical per- sonnel can utilise video conferencing software such as Zoom to host training sessions, with screen sharing capability if further clarification is required on manuals and a whiteboard function to illustrate issues from pic- tures taken inside build- ings.
In most situations, we can advise and help trou- bleshoot onsite controller problems without having to physically travel to the site.
Stockyard Industries is at the forefront of the pig industry in Australia with building design and construction, ventilation systems, feed systems and feeders, electronic sow feeding, penning from weaners to sows, farrow- ing systems and various consumable items used in piggeries.
Stockyard understands strong customer service is key for production facili- ties, particularly coming into winter when venti- lation rates change from summer vent to minimum vent.
For Big Dutchman 307pro controllers at- tached to BigFarmNet, our technicians have the ability to log into the farm and controller from any

The resistant bugs are being spread from the poultry to the staff and then to their families.
A large 2019 Dutch study of the prevalence of specific resistance genes involving thousands of isolates found most ac- quired resistance was at- tributed to human to hu- man transmission within or between households (60 percent).
Comparatively, Austral- ia makes a strong contri- bution to good antimicro- bial resistance practice.
And pig farm workers carry resistance genes closely related to those in swine.
We are going to be asked to do more through reduc- ing the use of antibiotics, optimal husbandry, high biosecurity standards and feed quality.
It is a complex field.
Hospital environments were the important source of human infections.
Environmental contact (wild birds and swimming in fresh water) accounted for 2.6 percent of resist- ance carriage.
Antimicrobial resistance shows little signs of abat- ing in the medium-term.
