Overview

''Naem'' is a red-colored, semi-dry lactic-fermented pork sausage in Southeast Asian cuisine prepared using minced raw pork and pork skin, significant amounts of cooked sticky rice, chili peppers, garlic, sugar, salt and potassium nitrate. Minced beef is sometimes used in its preparation. After the mix is prepared, it is encased in banana leaves, synthetic sausage casings or tubular plastic bags and left to ferment for three to five days. ''Naem'' has a sour quality to it due to the fermentation, in which lactic acid bacteria and yeasts grow within the sausage. The lactic acid bacteria and yeasts expand by feeding upon the rice and sugar, and the use of salt prevents the meat from rotting.

Naem typically has a short shelf life, which can be extended through refrigeration. The sausage can be time-consuming and labor-intensive to prepare. It is typically stored at room temperature, which gives it a shelf life of around one week. It is produced all over Southeast Asia in slight variations.

''Naem'' is often consumed raw, (after fermentation has occurred), and is often accompanied with shallot, ginger, bird's eye chili peppers and spring onions. It is used as an ingredient in various dishes such as ''naem'' fried with eggs, '' Naem khao'' and ''Naem phat wun sen sai khai'', and is also consumed as a side dish and as a condiment. The cooking of ''naem'' significantly changes its flavor.

''Naem'' and rice are formed into balls, deep-fried, and then served broken atop the various ingredients.

Microbiology

''Naem'' has on occasion been contaminated with parasites such as ''Taenia solium'', ''Trichinella spiralis'', and enteropathogenic bacteria such as coliform bacteria and ''Salmonella''. It has been demonstrated that ''Salmonella'' growth is inhibited by the formation of lactic acid during the fermentation process. Use of the starter culture '' Lactobacillus curvatus'' has been shown to prevent "the outgrowth of pathogenic bacteria" in ''naem''. ''Naem'' is sometimes irradiated.

Regulations on bacterial content

The bacterial content in Thai sour pork products is regulated. There should not be more than of '' Escherichia coli O157:H7'', ''Staphylococcus aureus'' not more than , ''Yersinia enterocolitica'' not more than , ''Listeria monocytogenes'' not more than , ''Clostridium perfringens'' not more than , Fungi less than 10colony per gram, ''Trichinellaspiralis'' less than .
