Brucellosis in a Virginia meat-packing plant.
In a 13-month period, 45 male workers in a meat-packing plant in Virginia contracted clinical brucellosis confirmed by laboratory findings. From the study carried out on the human and animal populations and the environment, it appears that the cases occurred through exposure to infected swine. Of 2,275 swine serologically tested, 4.6% were positive for Brucella antibodies. Air sampling confirmed the presence of brucellae in the atmosphere. Although improvement of hygiene and exhaust systems in the plant may be of benefit, the disease can be eliminated only through surveillance of swine herds.

Respiratory disorders among cheese makers - Pathological action of acarids
Les troubles respiratoires des fromagers - Rôle pathologique des acariens. [in French]
Epidemiological survey carried out among 214 cheese makers, consisting of a questionnaire, a clinical examination including spirography and an immunological examination (skin tests and antigen search by immunoelectrophoresis), which disclosed the presence of a new allergen: an acarid of the genus Acarus siro present in cheese rinds, joint causative agent of these workers' respiratory disorders along with moulds of the Penicillium type. Out of 137 cheese makers examined, 32 had positive skin-test reactions to extracts from these acarids and in 54 cases serum precipitins against these antigens were found by immunoelectrophoresis.

Explosion hazards in compound feed and flour mill silos
Explosionsgefahren in Silos von Mischfutterbetrieben und Mühlenwerken [in German]
After making a few general points on dust explosions, the author examines in detail the causes of an explosion in a multiple-cell silo for the production of compound feeds. Tests have shown that electrostatic charges produced by the swirling of dust particles reach a voltage sufficient to ignite the air/dust mixture. A level of 1,200V is deemed critical. Even the free fall of dust when the cells are being filled can give rise to dangerous charges. As a preventive measure the author advocates appropriate design of the cells, an inert atmosphere, introduction of humidified air into the cells, etc.

Aflatoxins - Epidemiological study of their carcinogenicity during long-term low-level exposure of a factory population
Aflatoxinen - Epidemiologisch onderzoek naar de carcinogeniteit bij langdurige 'low-level' expositie van een fabriekspopulatie [in Dutch]
Part 2 of the study abstracted under CIS 74-452, presenting the results of dust concentration measurements and particle-size distribution analyses carried out in a peanut-oil processing plant. The data obtained served to calculate the exposure of the factory population studied (160 to 395µg/m³ per man-week). While there were 13 cases of tumour and 2 of liver damage among 55 exposed workers, there were only 4 cases of tumour and none of liver disease in a group of 55 matched controls. Thin-layer chromatographic analysis of urine samples from 2 workers exposed to 3µg of aflatoxins gave a negative result as to aflatoxin metabolites.

Factors determining the occurrence and course of erysipeloid
Faktory, obuslovlivajuščie pojavlenie i harakter tečenija ėrizipeloida [in Russian]
An analysis of the causes of erysipeloid cases recorded between 1967 and 1971 in a large Russian meat-industry undertaking is followed by recommendations for the prevention of this disease: identification of infection sources; study of the routes of propagation; wearing of metal mesh gloves; organisation of first-aid posts to detect and treat microtraumata. As a result of these measures, it was possible to reduce erysipeloid cases from 101 in 1970 to 40 in 1972 in the plant under investigation.

Environmental pollution due to industrial solvents used for the extraction of olive oil from pressed oilcake
L'inquinamento ambientale da solventi nelle industrie per l'estrazione dell'olio di oliva dalle sanse [in Italian]
Results of a survey carried out in several chemical extraction plants for olive oil in Latium (Italy) employing the trichloroethylene or hexane process, which was continuous in some plants, non-continuous in others. Air sampling was carried out at various points in these plants and the samples analysed by gas chromatography. Plants using hexane were subdivided according to the exact composition of the solvent marketed under that name, which is in fact a mixture of pentane, methylpentane, hexane, dimethylpentane, cyclohexane and benzene. The survey brought to light the following facts, among others: solvents containing more than 1% benzene were being used; in the plants using trichloroethylene, concentrations of this substance in the air exceeding the permissible TLV of 100 ppm were often discovered; in the plants using hexane, however, apart from the cases where the solvent used contained an inadmissible proportion of benzene, monitoring of various workposts showed values under the TLVs.

Relation between the elimination of chlortetracycline in urine and occupational exposure to this biological stimulant
Vylučování chlórtetracyklinu močí v závislosti na profesionální exposici tomuto biostimulátoru [in Czech]
The use of chlortetracycline (aureomycin) as a biological stimulant for the nutrition of domestic animals raises hygiene problems for persons working in environments contaminated by this substance. The authors studied experimentally the relationship between urinary excretion of chlortetracycline and degree of exposure, and then checked the results found in 13 persons working in a livestock fodder production plant. Manifest antibiotic activity was found in 54% of the urine samples. The maximum values recorded correspond to a daily level per os of 20 µg of chlortetracycline/kg of body weight; 20% of the positive results correspond to a level of 1 to 15 µg and 79% to a level lower than 1 µg.

Oil of juniper as an occupational allergen affecting the skin and respiratory tract
Wacholderbeeröl als Berufsallergen für Haut und Atemtrakt [in German]
Describes the anamnesis and findings in a case of eczema and bronchial asthma following occupational exposure to oil of juniper in spicing and smoking sausages. Allergic response to the substance was established by intracutaneous tests and antigen inhalation tests. The need is stressed, in case of positive anamnesis, to carry out tests with terpene mixtures from different sources if a given mixture unexpectedly fails to provoke a reaction. It is emphasised that the location chosen for application of the allergen does not greatly affect the reaction of the organism, i.e. the symptoms.

CIS 72-2730 Brucellosis in the United States, 1970
A survey of human burcellosis in the USA during the period 1961-1970. The number of cases decreased from 636 in 1961 to 411 and 224 in 1970, a decline which is explained by the marked drop in the incidence of the disease in animals. The major problem relates to swine, in which the rate of disease is about 1%. Numerous statistical data are presented in tables. Most cases of human brucellosis were found in packing plants, particularly in slaughtering areas. Several cases of infection occurred in maintenance personnel, etc., who had no contact with raw meat.

Health hazards in animal-feed mixing plants
Über das Arbeitsrisiko bei der Herstellung von Futtermischungen [in German]
The general health of 82 men and 103 women occupationally exposed to high concentrations of dust in feed-mixing plants was investigated. The working conditions (dust, microclimate and noise), the method used and the results of the clinical examinations are described. The incidence of chronic bronchitis was much higher than in the general population. Sputum from persons examined contained a high level of fungal components and a normal bacterial component. In the majority of cases, these bacteria were resistant to the antibiotics of the tetracycline group, which are added to feed mixtures. In 11% of the group, dust irritation had produced various types of topical dermatitis.

"Cheese-washers' disease" - Immunology and epidemiology
Die "Käsewascherkrankheit" - immunologische und epidemiologische Studien [in German]
Report on the medical history and the serological-examination results of 125 cheese-salters who, for many years, had had respiratory exposure to cheese mould (penicillium casei). In certain cases, the serological examination was supplemented by patch testing and lung function tests. A number of cases of particular interest from the differential-diagnosis point of view are described. The most common form of the disease leads to a chronic interstitial pneumopathy. The incidence of certain serological factors and typical symptoms and characteristics in the medical history clearly indicate the occupational origin of this disease. Analysis of data obtained from cheese-dealers shows that sensitisation is related not only to individual predisposition but also to working conditions which necessitate the adoption of suitable supervision and hygiene measures. Resuilts obtained by other workers in this field are indicated.

Effect of the working environment in animal-feed mixing premises on respiratory disease
Einfluss des Arbeitsmilieus in den Futtermischungsräumen auf die Erkrankungen der Atmungswege [in German]
Industrial hygiene studies in 42 Czechoslovak animal-feed plants revealed dust concentrations 6-85 times higher than the Czechoslovak MAC for inert dusts (10mg/m³). Numerous dust samples contained aspergillus, mucor, rhizopus and penicillium spores. 33% of male employees had chronic bronchitis (with some cases of emphysema); only 13% of the females were affected. Analysis of the occurrence and extent of bronchitic phenomena showed a statistically significant difference between smokers and non-smokers. More aspergillus and penicillium spores were found in the sputum of exposed males (8.5% in both cases) that in that of controls (1.9 or 6.9%); this indicates massive spore inhalation in animal-feed mixing. The authors consider that only hermetic enclosure of mixing and bagging plants can produce a fundamental improvement in working conditions.
