Spices are becoming increasingly important world-wide due to their effectiveness as natural antibiotics, the thing that makes the world nowadays tend to use spices instead of chemical drugs. However, this doesn’t mean they are free of some dangerous pathogens such as Klebsiella spp. which can lead to a wide range of illnesses, notably pneumonia, urinary tract infections (UTIs), and bacteremia. Although we don’t know the natural habitat of this bacterium we find that it thrives in herbs and spices, concluding thus that plants may be its natural habitat. The primary isolation of this bacterium was based first on its growth on general media and then isolation on selective media. Colonies of the microorganisms were counted on different media then Klebsiella was isolated from a selective media. The isolated colonies of Klebsiella were circular, dome-shaped, 3-4 mm in diameter, with mucoid sticky edges, and surrounded by capsule. After this we chose the typical colony and identified it using Polymerase chain reaction PCR and biochemical tests. Our results showed that 32% of examined specimen contained Klebsiella spp.

Enterobacter sakazakii is considered an opportunistic pathogen that has been associated with severe lethal infections especially in neonates, elderly, and Immunocompromised adults. E. sakazakii is a Gram negative, facultative anaerobes rod-shaped bacterium. It belongs to the family Enterobacteriaceae and genus Enterobacter. Although we don’t know the natural habitat of this bacteria we find that it exists in high rate in herbs and spices which indicates that plant may be this natural habitat.
This study has been conducted to identify the levels of heavy metals (lead, cadmium, nickel, cobalt, copper, iron, manganese, and zinc) in the following spices: Nutmeg, turmeric, cinnamon, ginger, cardamom, nigella sativa, black pepper, cumin, coriander, curry, and mixed spices.
The concentrations of Copper (Cu) and Zinc (Zn) in samples of some spices available at some local markets in Syria were determined, after nitric digestion, using Atomic Absorption Spectrometry. The study showed differences in metal concentrations according to the edible part. Studied heavy metals were present in all samples at different levels. The concentration of Copper (Cu) and Zinc varied from trace to higher concentration. The maximum level of Copper (Cu) in the spices samples was 0.668 mg/kg. The maximum level of Zinc (Zn) in the spices samples was 2.523mg/kg. The analytical results obtained for the heavy metals indicate that the Copper and Zinc were present in all samples at concentration well below the acceptable daily intake recommended by the World Health Organization.
Formaldehyde is classified by the World Health Organization (International Agency for Research on Cancer) as a carcinogen in Group 1. The upper limit allowed for use in cosmetic products as a preservative has to not exceed 0.2%. This study aims to detect and determine formaldehyde level in some cosmetic products available in the local market using acetyl acetone method. Formaldehyde was detected in 77% of the studied cosmetic products (49 samples) despite the fact that most of them were not labeled formaldehyde or formaldehyde donor preservatives (about 70%). The amount of formaldehyde in keratin samples were higher than the allowed limit (0.34% -11.73%) except one sample 0.18%. pH decrease and temperature increase of keratin samples led to an increase of formaldehyde level as a result of its release from preservatives.
Three hundreds and thirty samples of raw milk and some of the Syrian dairy products collected during 2002-2003 from different areas of Syria, and were used to detect the presecne of Listeria in these products. Results indicated that mainly L. mono cytogenes and to a lesser degree L.innocua and L.ivanovii were found in these products. The perecentage of violating of the Syrian standards was 4 % in raw milk, 0.0% in pasteurized milk, 2% in white cheese, 0.5% in shinglish and 0.0% in ice cream. And it has been deterhmined the identity of the isolated bacterial species of Listeria from the above-mentioned products, where L. monocytogenes was dominant, and to a lesser estent were L. innocua and L. ivanovii.
