Electrolyte content of salt-replacement seasonings.

As Americans attempt to reduce sodium consumption, demand for alternatives to ordinary table salt is increasing. Some of the products now marketed as replacements have substantial levels of sodium chloride. They may, however, also provide potentially beneficial electrolytes, such as potassium, calcium, and magnesium. This report reviews the role of electrolytes in blood pressure regulation and reports levels of sodium, chloride, potassium, magnesium, and calcium in 13 seasonings available commercially as alternatives to table salt. Samples of seasonings were purchased from local supermarkets and health food stores and analyzed for electrolyte content using methods approved by the Association of Official Analytical Chemists (AOAC). Sodium content ranged from 2 mg to 2,180 mg/tsp and sodium:potassium ratio from 0.07 to 2,460. Calcium and magnesium levels in most seasonings were modest, with the exception of kelp-based seasonings, which provided approximately 50 mg calcium and 35 mg magnesium per teaspoon.

Aflatoxins in domestic and imported foods and feeds.

Aflatoxins, metabolic products of the molds Aspergillus flavus and A. parasiticus, may occur in foods and feeds. These toxins cannot be entirely avoided or eliminated from foods or feeds by current agronomic and manufacturing processes and are considered unavoidable contaminants. To limit aflatoxin exposure, the U.S. Food and Drug Administration (FDA) has set action levels for these toxins in foods and feeds involved in interstate commerce. FDA continually monitors food and feed industries through compliance programs. This report summarizes data generated from compliance programs on aflatoxins for the fiscal year 1986. Commodities sampled included peanuts and peanut products, corn and corn products, tree nuts, cottonseed, milk, spices, manufactured products, and miscellaneous foods and feeds. Correlations were highest between aflatoxin contamination and geographical areas for corn/corn products and cottonseed/cottonseed meal. Higher incidences of aflatoxin contamination in corn and corn products designated for human consumption were observed in samples collected in the southeastern states (32 and 28%, respectively). A higher incidence of contamination was observed in corn designated for animal feed from Arkansas-Texas (74%) than from the southeastern states (47%). Only 3% of feed corn from corn belt states contained detectable aflatoxins. All aflatoxin-contaminated cottonseed was collected in the Arizona-California area; 80% of cottonseed meal analyzed from this area also contained detectable levels of aflatoxins.(ABSTRACT TRUNCATED AT 250 WORDS)

Microscopic detection and identification of various substitute vegetable tissues in ground horseradish.

Turnip root, parsnip root, potato tuber, and corn kernels have been used as adulterants in the preparation of horseradish sauce and horseradish powder. The diagnostic histological features of horseradish root and its known adulterants are described and illustrated as viewed through a polarizing microscope with cross polars and a first order red plate. A procedure which can be used to detect any of the known adulterants in horseradish is described. The adaptation of a previously reported semiquantitative method is also discussed.

Microbiological survey of selected imported spices and associated fecal pellet specimens.

A microbiological survey was performed on 4 selected imported spices: black peppercorns, white peppercorns, coriander, and fennel seed. Aerobic plate count values ranged from 10(4) to 10(7) colony-forming units (CFU)/g for black and white peppercorns and from 10(3) to 10(5) CFU/g for coriander and fennel seed. Combined results of the 3-tube most probable number procedure and the API 20E kit indicated the presence of Escherichia coli in 4 test samples of black peppercorns, 1 test sample of white peppercorns, and 1 test sample of coriander. Two test samples of black peppercorns were positive for Salmonella contamination. Among the various Enterobacteriaceae isolated from the spices, Enterobacter cloacae and Klebsiella pneumoniae were found most frequently in all spice types. Of 18 mammalian and avian fecal pellets removed from the spices and analyzed microbiologically, E. coli was found in only 2 pellet specimens. There was no apparent relationship between the enteric microflora found in spices and those found in the fecal pellets.

Clove cigarettes. The basis for concern regarding health effects.

The smoking of clove cigarettes has been associated with 13 cases of serious illness in the United States, including hemorrhagic pulmonary edema, pneumonia, bronchitis, and hemoptysis. We describe a patient in whom, after she smoked a clove cigarette, pneumonia complicated by lung abscess developed. Her lung disease may have been caused by aspiration pneumonia as a consequence of pharyngolaryngeal anesthesia from clove cigarette smoke. Clove cigarettes appeal to adolescents experimenting with smoking practices and may influence the development of later smoking habits.

Comparison of rapid perfringens medium and lactose sulfite medium for detection of Clostridium perfringens.

Two tubed media, lactose sulfite (LS) and rapid perfringens medium (RPM), were evaluated and compared for their ability to detect and enumerate Clostridium perfringens in inoculated and naturally contaminated samples. In a 3-tube most probable number system, the number of organisms recovered from spiked samples was several-fold higher with RPM than with LS and was close to the numbers inoculated. Levels detected in 15 naturally contaminated samples were also higher with RPM. Only 13 of the samples were positive for C. perfringens with LS medium. These results indicate that RPM is a more effective medium than LS; therefore, its use is recommended.

Rapid detection of Clostridium perfringens: comparison of lactose sulfite broth with tryptose-sulfite-cycloserine agar.

The lactose sulfite (LS) medium recommended for the detection and identification of Clostridium perfringens in foods was compared with a reference method using tryptose-sulfite-cycloserine (TSC) agar for the enumeration of this organism in a variety of foods and food ingredients. C. perfringens was detected and enumerated in 17 of the 54 samples examined with LS broth, but its presence could be confirmed in only 9 of the samples with TSC agar. In only 2 instances, C. perfringens was detected on TSC agar but not in LS broth. A positive response (FeS + and gas +) in LS broth incubated at 46 degrees C always corresponded to the presence of C. perfringens; whereas the black colonies formed on TSC agar incubated at 37 degrees C were frequently found to be Clostridium species other than C. perfringens. Thus, because of its highly selective nature, LS broth was superior to TSC agar for enumerating and confirming the small numbers of C. perfringens that were present in a majority of the samples. This was especially true when other clostridia were also present. Besides its greater selectivity and sensitivity, LS broth had the additional advantages of requiring less work and giving confirmed results within 24-48 h compared with 3 days for the TSC agar method.

Evaluation of the health hazard of clove cigarettes. Council on Scientific Affairs.

Resolution 43 (1987 Annual Meeting), adopted by the House of Delegates, resolved that the American Medical Association study the dangers associated with clove cigarettes, that policy recommendations regarding regulation of clove and other tobacco additives be developed, and that this information be made available to physicians and the public. Clove cigarettes are tobacco products. They therefore possess all the hazards associated with smoking all-tobacco cigarettes. In addition, inhaling clove cigarette smoke has been associated with severe lung injury in a few susceptible individuals with prodromal respiratory infection. Some individuals with normal respiratory tracts have apparently suffered aspiration pneumonitis as the result of a diminished gag reflex induced by a local anesthetic action of eugenol (the active component of cloves), which is volatilized into the smoke. The American Medical Association has an existing policy vigorously opposing the use of any tobacco product; no exemption from this policy is made for clove-containing cigarettes.

Bullous contact allergy from cinnamon.

A young Malay female presented with a bullous eruption as a manifestation of contact allergy to cinnamic aldehyde in cinnamon. The clinical and histological features resembled bullous pemphigoid but immunological markers for pemphigoid were absent. The patient responded to a short course of oral steroids. Contact allergy can mimic pemphigoid.
