Salmonella in Milk review

Researcher E.H. Marth a researcher has already stated in 1969 that salmonella can occur in raw in the Journal of Science, published by the Elsevier. Salmonellosis epidemics were caused by the consumption of contaminated unpasteurized milk (Marth, 1969). Milk that has been pasteurized has also contributed to the spread of these organisms, which originated in the potentially contaminated after heating. Salmonellae have been identified in various dairy products in the United States and globally (Marth, 1969).

A range of that are occasionally detected in unpasteurized milk might cause illness. Brucella, Campylobacter, Cryptosporidium, , Listeria, and Salmonella are among these pathogens (CDC, 2017) Milk and dairy products are a vital part of the human diet since they contain all of the elements needed for bodily . The contamination of milk and its products does not diminish their , but it does cause the transmission of pathogens (Singh et al., 2018).

Between 1993 to 2012, 127 associated with raw milk were reported to the CDC. There were 1,909 illnesses and 144 hospitalizations related to these outbreaks (CDC, 2017). Campylobacter, Shiga toxin-producing E. coli, and Salmonella were responsible for the majority of outbreaks. A significant proportion of raw milk outbreaks include children (CDC, 2017). From 2007 to 2012, at least one kid less than 5 was involved in 59% of the raw milk outbreaks reported to the CDC. In these outbreaks, children aged 1 to 4 accounted for 38 per cent of Salmonella infections and 28 per cent of illnesses caused by Shiga toxin-producing E. coli, which may cause renal failure and death (CDC, 2017).

As most salmonella cases are linked to egg products or from an unknown origin, historical has shown that milk and dairy products can be a good breeding ground for salmonella. According to the EFSA (2019), there have been 24 cases of salmonella contamination in 2018, other products and linked to Salmonella can be seen on the link below. More information about Salmonella can be found on the Salmonella knowledge sheet.

2000 consumers ill in the US by mr. Cheese


Salmonella Newport


Raw milk cheese




Utah in the United States


Possibly 2,100 people in the state of Utah (USA), became ill with Salmonella Newport since 2009 by contaminated raw milk cheese. Around Salt Lake City were attributed eleven infections in 2009, this type of cheese. Local authorities warned of the cheese, which was sold at malls including from the trunk of a car. In three years, the man-made 73 victims, but because of underreporting is the weekly number of probably thirty times higher. The man who bought the milk may be illegal at a local dairy.


On December 1 2011 Mr Fidel Gomez (aka Mr Cheese) received from the authorities in Utah a fine of $500 for the illegal and sale of cheese without a license and for selling cheese without a label. Given the seriousness of the facts, Mr Cheese came off it lightly.


Risk of disease much greater by raw milk


Salmonella and Campylobacter






The United States

Cases Salmonella in milk

In the United States were reported from 2009 to 2014, 760 cases per year by unpasteurized dairy. The most common causes were Campylobacter and Salmonella. In the US, only 3.2% of the population consume unpasteurized milk and 1.6% consume unpasteurized cheese. Statisticians calculated that the probability was 840 times as much of getting ill from these products as of unpasteurized dairy. Concluding cases of dairy disease occur in 96% of cases due to unpasteurized dairy.


One can wonder why no one has ever published anything in a scientific journal about how safe unpasteurized dairy is, but always about how not safe unpasteurized dairy is. The reason is, of course, that unpasteurized dairy is many times more unsafe. There has been a lot of scientific research into the of unpasteurized dairy versus pasteurized dairy. It is clear that there is no difference in that area.
