Vedran Lončarić, ECOLAB: "Understanding Contamination Pathways is Key to Effective Mastitis Prevention"
A two-day industry seminar by CID LINES (Ecolab) on improving dairy production efficiency is taking place in Budapest on April 20-21, 2026. At the event, ECOLAB Dairy Farm Technical Manager Vedran Lončarić presented a practical approach to managing mastitis through the analysis of contamination pathways, one of the key factors in reducing farm losses.
Vedran Lončarić's presentation was part of the seminar “Elevating Dairy Performance: Delivering Safety, Quality, and Profitability fr om Farm to Family,” organized by CID LINES, an Ecolab company.
The event brought together dairy industry professionals and experts, focusing on the exchange of scientific data, practical solutions, and experiences aimed at improving safety, quality, and profitability standards in dairy production.

"Not all mastitis is the same. Understanding contamination pathways is the key. Identifying the dominant pathway on each farm allows for the correct preventive strategy to be chosen."
According to him, incorrect diagnosis of the disease causes leads to ineffective costs and the growth of chronic problems in the herd.
It affects:
Contagious
Transmitted from cow to cow through milking equipment, staff hands, or direct contact.
Main pathogens: Staphylococcus aureus, Streptococcus agalactiae.
"These bacteria can hide inside cells, making them particularly resilient."
Control focus: milking hygiene, disinfection, culling of chronic animals.
Environmental
Arises from the environment — bedding, water, manure.
Main pathogens:
* E. coli
* Klebsiella
* environmental streptococci
"Even short-term presence of bacteria can lead to severe clinical cases."
Control focus: cleanliness, dry bedding, udder preparation and protection.
Mixed
The most common scenario in practice.
"Most farms face a combination of pathways, therefore requiring a comprehensive approach."
Action algorithm:
1. determine the type of mastitis
2. identify the dominant transmission pathway
3. implement targeted measures
"Each pathway requires its own strategy. Universal solutions do not exist."
"Our task is to create conditions wh ere bacteria cannot establish and spread."
Thus, mastitis becomes not an inevitable problem but a manageable risk with a systematic approach and accurate diagnosis.

"Not All Mastitis is the Same"
The key point of Lončarić's presentation was the need to reject a one-size-fits-all approach to mastitis."Not all mastitis is the same. Understanding contamination pathways is the key. Identifying the dominant pathway on each farm allows for the correct preventive strategy to be chosen."
According to him, incorrect diagnosis of the disease causes leads to ineffective costs and the growth of chronic problems in the herd.
Mastitis as an Economic Factor
The expert emphasized that mastitis is primarily an economic issue.It affects:
- reduced milk yields and quality
- increased treatment costs
- culling of animals
- increased use of antibiotics
Three Contamination Pathways — Three Different Strategies
The management approach is based on dividing mastitis into three types:Contagious
Transmitted from cow to cow through milking equipment, staff hands, or direct contact.
Main pathogens: Staphylococcus aureus, Streptococcus agalactiae.
"These bacteria can hide inside cells, making them particularly resilient."
Control focus: milking hygiene, disinfection, culling of chronic animals.
Environmental
Arises from the environment — bedding, water, manure.
Main pathogens:
* E. coli
* Klebsiella
* environmental streptococci
"Even short-term presence of bacteria can lead to severe clinical cases."
Control focus: cleanliness, dry bedding, udder preparation and protection.
Mixed
The most common scenario in practice.
"Most farms face a combination of pathways, therefore requiring a comprehensive approach."
Control Starts with Understanding
Lončarić emphasizes that effective mastitis management begins not with treatment but with diagnosis.Action algorithm:
1. determine the type of mastitis
2. identify the dominant transmission pathway
3. implement targeted measures
"Each pathway requires its own strategy. Universal solutions do not exist."
The Environment as a Major Risk Factor
The speaker paid special attention to the pathogen habitat: in contagious mastitis, the condition of the teat skin plays a key role, while in environmental mastitis, the conditions of animal maintenance are crucial."Our task is to create conditions wh ere bacteria cannot establish and spread."
Common Farm Mistakes
Among the main problems:- poor milking hygiene
- contaminated equipment
- staff errors
- insufficient attention to the dry period
Shifting to Prevention
The main conclusion of the presentation is the need to change the approach. "Effective protection begins with the right understanding: each contamination pathway requires its own hygiene strategy."Thus, mastitis becomes not an inevitable problem but a manageable risk with a systematic approach and accurate diagnosis.
