Generated Summary
This document from the Centers for Disease Control and Prevention (CDC) provides information about raw milk, answering questions about its risks, and potential health impacts. It uses a question-and-answer format, covering the definition of raw milk, associated health risks, who is most at risk, and whether raw milk is safe for consumption. The document also references outbreaks and provides links to further resources and studies. The document does not present a traditional study with specific methodologies but rather compiles information to educate the public on the dangers of raw milk. The approach is primarily informational and educational, aiming to inform consumers about the hazards of raw milk consumption and to dispel common misconceptions.
Key Findings & Statistics
- It is thought that less than 1% of milk sold to consumers in the United States has not been pasteurized.
- From 1998 through 2011, 148 outbreaks due to consumption of raw milk or raw milk products were reported to CDC. These resulted in 2,384 illnesses, 284 hospitalizations, and 2 deaths.
- Most of these illnesses were caused by Escherichia coli, Campylobacter, Salmonella, or Listeria.
- Among the 104 outbreaks from 1998-2011 with information on the patients’ ages available, 82% involved at least one person younger than 20 years old.
- The number of outbreaks in the United States caused by nonpasteurized (raw) milk increased from 30 in 2007-2009 to 51 in 2010-2012.
- Most (77%) outbreaks were caused by Campylobacter and most (81%) occurred from consumption of nonpasteurized milk purchased from states where the sale of nonpasteurized milk was legal.
Other Important Findings
- Raw milk can carry harmful bacteria and other germs that can cause serious illness.
- Illness can occur from the same brand and source of raw milk that people had been drinking for a long time without becoming ill.
- A wide variety of germs that are sometimes found in raw milk, can make people sick, including bacteria (e.g., Brucella, Campylobacter, Listeria, Mycobacterium bovis, Salmonella, Shiga toxin-producing Escherichia coli [e.g., E. coli O157], Shigella, Yersinia), parasites (e.g., Giardia), and viruses (e.g., norovirus).
- The risk of getting sick from drinking raw milk is greater for infants and young children, the elderly, pregnant women, and people with weakened immune systems.
- There are no health benefits from drinking raw milk that cannot be obtained from drinking pasteurized milk that is free of disease-causing bacteria.
Limitations Noted in the Document
- The document itself does not explicitly state limitations in the provided text.
- The document primarily serves as an informational resource, and the information is not presented as a formal research study with methodology.
- The document acknowledges that the actual number of illnesses associated with raw milk is likely greater due to underreporting.
- The document is a compilation of information, not a primary research article. The data and statistics presented are based on existing reports and studies.
- The document does not provide original research or data analysis.
Conclusion
The CDC’s document on raw milk serves as a critical resource for understanding the risks associated with consuming unpasteurized milk. The information provided underscores that raw milk can cause serious infections due to harmful bacteria and germs, leading to a range of health issues from diarrhea to severe complications like kidney failure and death. The document emphasizes that no health benefits are associated with raw milk that are not available through pasteurized milk, and it highlights the vulnerability of certain populations, such as infants, the elderly, pregnant women, and those with weakened immune systems. The documented outbreaks and statistical data highlight the severity of the risks involved and the unpredictable nature of contamination in raw milk. The document also points out that because not all cases of foodborne illness are recognized and reported, the actual number of illnesses associated with raw milk is likely greater. Consumers are strongly cautioned to avoid raw milk to prevent potential health risks. The CDC’s publication aligns with its mission of public health education, aiming to protect people by informing them of the dangers associated with raw milk and promoting safer alternatives such as pasteurized milk. The document’s clear presentation and readily available information make it a vital tool for public health professionals, consumers, and anyone seeking to make informed choices about their food consumption.
