National Mastitis Council 52nd Annual Meeting
Presentations from General Session 3“Milk Quality Around the World”
Milk quality continues to gain more importance as consumers become more aware and as countries import and export dairy products. A session held during the NMC 52nd
Annual Meeting (January 2013) provided a brief overview of milk quality from some of the dairy industries across the globe.
The following presentations include demographic information, milk quality parameters, and other unique practices from:
• Colombia • Germany
• Italy • New Zealand
• Spain • United States
• Uruguay • Canada
• Chile • Great Britain

MILK PRODUCTION IN COLOMBIA
Holstein, Normande, Jersey, Brown Swiss, Zebu and its crossbreeds
Average herd size: ~30 cows
Milk production: 5,500 M of kg of milk/year
Most coming from Zebu cows (high number with low milk yield)

MILK QUALITY IN COLOMBIA
Most of mastitis cases caused by contagious
Strep. agalactiae bulk tank prevalence: 42%
SCC is not part of the current regulation on milk quality
BC still high (hand milking?), current regulation: max 175,000 cfu/mL, no actions taken if higher (processors)

• About 50% marketed as raw milk
• Milk for pasteurization and dairy products is tested for β-lactam
• Bonuses paid for being free of TBC and brucellosis

Raw Milk • Raw milk can be purchased directly at farm in Italy. • Farmers should follow more stringent rules on milk quality
(SCC, TBC) • Milk (but not farm) should be certified free from S.aureus,
Str.agalactiae, Salmonella spp, M.paratuberculosis, E.coli O157:H7, Listeria spp, and Campylobacter spp.
• The two most important and tasty Italian cheeses (Parmigiano Reggiano, Grana Padano) and many other are made with raw milk

Future initiatives under consideration • Application on wider scale of herd health management
programs by practitioners after specific training programs.

Most recent success in milk quality
• The number of farms that eradicated S.aureus IMI after following voluntary programs
• > 100 herds nationwide • > 90% success • Applied by several groups/associations (vets,
farmer ass., dairies)

Biggest frustration in milk quality • Still most farmers (with poor quality) believe that SCC and
mastitis are not correlated and the source of high SCC are not intramammary infections

MILK QUALITY PROGRAMS (MQP)
About 100 people (veterinarians) work in Milk Quality in Spain
Producers are in MQP to improve milk quality, less mastitis and more premiums
Many producers are in MQP because they received more subsidies
It impossible improve Milk Quality without advice

Our goals • To improve the exchange of knowledge on
intramammary infections among the member countries.
• Apply that knowledge considering epidemiologic differences of the several milk production systems present in Latin-America
• Help to produce quality milk considering both animal welfare and an environmentally sustainable milk production.

• The result has been the attainment of >90% of Grade A milk.
• Dairy cows: 1,000,000
• People: 3,200,000
• Dairy producers: 4,000

CHILE • Milk production in Chile is
mainly located in the central, central-south and south part of the country.
• Dairy operations with year-
round and seasonal confinement are usually found in the central and central-south zones.
• Grazing systems are common in the south zone.
![Page 46: Milk Quality Around the World](https://reader033.fdocuments.us/reader033/viewer/2022052522/554aad75b4c905e4668b5037/html5/thumbnails/46.jpg)
• International milk price influenced the pace of growth of milk production in Chile. With a +1% growth trend since 2006.
• Chilean average per capita annual milk consumption between 115 and 132 L during the last 20 years, with a record consumption of 145 L for 2012.
• Herd productivity in Chile has doubled during the last 8 years.
• The number of dairy operations and total number of milk cows have decreased.
![Page 47: Milk Quality Around the World](https://reader033.fdocuments.us/reader033/viewer/2022052522/554aad75b4c905e4668b5037/html5/thumbnails/47.jpg)
• A national strategic plan to support competitiveness and milk quality of the dairy industry was created in 2004 with the Chilean Dairy Consortium (Consorcio Lechero) formed by producers, processors, and research institutions.
• Average SCC in dairy herds, however, have remained around 300,000 cell./mL during the last 10 years.
![Page 48: Milk Quality Around the World](https://reader033.fdocuments.us/reader033/viewer/2022052522/554aad75b4c905e4668b5037/html5/thumbnails/48.jpg)
Pathogens associated to intramammary infections in Chilean dairy herds
• Streptococcus agalactiae prevalences are reported to be less than 1% among herds.
• Staphylococcus aureus has remained the main pathogen isolated from milk samples during the last 50 years.
• Historical reports from both the central and central-south zones Chile, shown an undulating pattern, ranging between 12 to 50% of culture-positive samples.
• For the south zone reports of Staph. aureus show a slightly increasing trend with current values around 40% of the culture-positive milk samples
![Page 49: Milk Quality Around the World](https://reader033.fdocuments.us/reader033/viewer/2022052522/554aad75b4c905e4668b5037/html5/thumbnails/49.jpg)
• Mycoplasma spp. Prevalence of 7% Mycoplasma-positive bulk tank milk (BTM) samples was reported in Chile.
• However the presence of Mycoplasma in BTM, and Mycoplasma IMI within and between Chilean dairy herds is mostly unknown.
• Escherichia coli reported between 4% and 40% of the culture-positive milk samples for the south and central zones of Chile, respectively.

Current Milk Quality „Issues“
• Milk quality is on a very high level in Germany! • Attention is paid to
– Use of antibiotics | avoiding residues in milk political discussion about resistant strains of different germs
– Residues of cleaners | disinfectants especially quarternary ammonium compounds and chlorine compounds
– Pathogenes
• Evolving topic tuberculosis, sporadic but „hot spots“ with high level of public attention

Summary • Overall average BTSCCs from the four monitored FMOs
declined during 10 of the past 11 years.
• BTSCCs peak in July and August and are lowest during winter and spring months.
• Since 2001, overall BTSCC have decreased ~35%.
• BTSCC in 2012 will be the lowest of all years monitored.
• EU and FDA are pushing producers and increasing the quality of the U.S. milk supply.

Other milk quality issues
• Adulterants – Inhibitor and added water testing
under provincial regulation
• Organisms – Varies between provinces – LPC, PI and CC counts – Mastitis pathogen PCR testing
• Raw Milk – Sale prohibited by federal law

Initiatives
• Dairy Farmers of Canada promoted a reduction in BTSCC limit to 400,000
• Adopted for August 1, 2012 by all 10 provinces
• Education programs • Regulatory reform

Regulatory reform
Somatic Cell Count
• Weekly sample for monthly geomean
• Monthly geomean for rolling 3 month
• Penalties (year) – 1ST infraction $5/hL – 2nd $10/hL – 3rd $15/hl + board
review – 4th $20/hL/ + shutoff
Bacteria counts
• Weekly sample • 2 samples in a row
= infraction • No single test used
in 2 infractions • Same penalties as
SCC – Additional $3 level
in year 1
