This study on pasteurization provides important information that underpins disease preparedness and response beyond the U.S., should it be required.”
Ed Hutchinson, senior lecturer at the MRC-University of Glasgow Centre for Virus Research, echoed these sentiments, highlighting the urgent need to confirm pasteurization’s efficacy. He noted, “We urgently needed to answer whether pasteurization made milk safe. We have now shown that the temperatures used in pasteurization should rapidly inactivate all influenza viruses. However, we also found that ‘raw’ or unpasteurized milk can carry infectious influenza viruses.”
Both experts stress that raw milk can harbor various pathogens. Hutchinson adds, “We would caution people against drinking it in areas where cattle might be infected with H5N1 influenza.” He further warned, “Human infections with H5N1 influenza viruses can be hazardous, and they also give the virus more opportunities to adapt to growing in humans with the chance of becoming able to transmit to humans. Pasteurizing milk in affected areas is a good way to minimize these risks.“
The Critical Public Health Role of Pasteurization in Combating H5N1
The findings of this study have important public health implications. Pasteurization is crucial for safe milk consumption and plays a significant role in preventing zoonotic transmissions like H5N1.

Confronting the Invisible Foe: Tackling Mycotoxins for Healthier Herds and Safer Milk
Mycotoxins—toxins from mold in feed—threaten livestock health and milk safety in dairy farming. Common mycotoxins like aflatoxins (AFB1), deoxynivalenol (DON), fumonisins (FUM), T-2 toxin, and zearalenone (ZEN) can harm dairy cows by affecting liver function, immunity, and overall productivity. These toxins can enter milk, posing risks to human health.
Anti-mycotoxin feed additives such as Hydrated Sodium Calcium Aluminosilicate (HSCA) and Mycotoxin Deactivators (MD15 and MD30) have been developed to combat these dangers. These additives bind or transform mycotoxins, making them less absorbable and reducing their levels in the cow’s system. This study examines these additives’ effectiveness by measuring mycotoxin levels in milk, urine, and blood plasma, ensuring they don’t harm cow performance or nutrient absorption.
Let’s delve into the essence of the research. This study was meticulously conducted, involving twelve carefully selected multiparous cows. These cows, averaging 165 days in milk, 557 kg in body weight, and an initial milk yield of 32.1 kg/day, were grouped based on parity, milk yield, and days in milk. They were then assigned to a 4 × 4 Latin square design over 21-day periods, with the last seven days dedicated to data collection. This rigorous methodology ensures the reliability and applicability of the study’s findings to real-world dairy farming scenarios.
The cows received different treatments to test the anti-mycotoxin feed additives:
Mycotoxin group (MTX): Basal diet (BD) without additives.
Hydrated sodium calcium aluminosilicate (HSCA): BD plus 25g/cow/day.
Mycotoxin deactivator 15 (MD15): BD plus 15g/cow/day of Mycofix® Plus.
Mycotoxin deactivator 30 (MD30): BD plus 30g/cow/day of Mycofix® Plus.
All cows were exposed to a mycotoxin blend, including 404 μg aflatoxins B1 (AFB1), 5,025 μg deoxynivalenol (DON), 8,046 μg fumonisins (FUM), 195 μg T2 toxin (T2), and 2,034 μg zearalenone (ZEN) for the last seven days of each period.
This setup allowed the researchers to evaluate the effects of each treatment on mycotoxin levels in milk, urine, and blood, as well as the cows’ overall performance and health.
