Mayonnaise Gets such a bad Rap when it comes to food poisoning, it is justified?

Remember that my mother warning me as a kid I could get food poisoning from a sandwich that was left out of the refrigerator which had mayonnaise in it. This is a legitimate concern on the part of my mother

The answer is no. In fact, mayonnaise is not very conducive to bacterial growth. This is due to the following factors; the ingredients in mayonnaise prepared commercially include pasteurized eggs, salt and an acid like vinegar (acetic acid) citric acid or something.

Mayonnaise manufactured in the United States is very acidic, with a pH of 3. 6-4. 0. not only this, but the organic acids used in commercially prepared mayonnaise has other antimicrobial properties.

Studies have shown that the lethal effect of mayonnaise on foodborne pathogens has been well documented. According to Michael p. Doyle, Ph.d., Professor and Director of the center of the University of Georgia food safety and quality improvement, more harmful bacteria, including e. coli O157: H7, Salmonella and Listeria monocytogenes, die within hours in the presence of mayonnaisedue to its acidity.

This is true for traditional mayonnaise, low-cal and mayonnaise-based salads.

Antimicrobial protection also extends to potato and macaroni salads containing Mayo.

The issue of food safety is related to food such as ham, chicken and potatoes that are often prepared with mayonnaise that are susceptible to bacterial growth.

If mayonnaise is left at room temperature after opening is a matter of food safety The problem is more related to the quality of taste of mayonnaise can deteriorate if not kept refrigerated. This is the reason why the labels on bottles of mayonnaise suggest refrigeration after opening.

It is believed that the reputation of "dangers of mayonnaise" began when people would prepare homemade mayonnaise. Not using standardized values of salt and vinegar and the use of unpasteurized eggs surely contributed to the problem with the growth of pathogenic bacteria.

So go ahead and enjoy this salad sandwich or pasta, if he has mayonnaise, safety is, in fact, increased.
