Topic:Food Safety

Food safety in horses encompasses practices and standards aimed at ensuring the health and well-being of horses through the management of their dietary intake. This includes the assessment and control of potential contaminants and pathogens in equine feed and water sources. Key concerns in equine food safety include the presence of mycotoxins, pesticide residues, and bacterial pathogens such as Salmonella and Clostridium botulinum. Proper feed storage, sourcing, and preparation are integral to preventing foodborne illnesses in horses. This page compiles peer-reviewed research studies and scholarly articles that explore the detection, impact, and management of food safety issues in equine nutrition.
Urinary excretion of theobromine in horses given contaminated pelleted food.
Veterinary research communications    January 1, 1991   Volume 15, Issue 2 107-116 doi: 10.1007/BF00405142
Delbeke FT, Debackere M.A high pressure liquid chromatographic (HPLC) method for measuring the theobromine content in cocoa husks, pelleted food and horse urine is described. Starting with 2 ml of urine, concentrations of 500 ng/ml could easily be detected. When feed containing 38.4 mg of theobromine was given twice daily to horses for 2 1/2 days, two days were needed after the last intake before the theobromine concentrations fell below the threshold value of 2 micrograms/ml. The time at which the peak excretion rate occurred varied from 2 to 12 h after the last administration, while the excretion rate seemed to be ...
Chloramphenicol 3. Clinical pharmacology of systemic use in the horse.
Australian veterinary journal    January 1, 1991   Volume 68, Issue 1 5-8 doi: 10.1111/j.1751-0813.1991.tb09828.x
Page SW.The use of chloramphenicol in the horse is now prohibited as horses are classified as food-producing animals. However, chloramphenicol has until recently been widely available for oral, intramuscular or intravenous administration. A critical appraisal of the published literature on the use of chloramphenicol in the horse clearly demonstrates that there are sound pharmacokinetic and microbiological reasons for concluding that chloramphenicol is not an appropriate antibiotic for systemic use. The short half-life of chloramphenicol in the horse, together with the broad range of minimum inhibitory...
Aspergillus flavus and aflatoxins B1, B2, and M1 in corn associated with equine death.
Archives of environmental contamination and toxicology    January 1, 1991   Volume 20, Issue 1 151-153 doi: 10.1007/BF01065342
Vesonder R, Haliburton J, Stubblefield R, Gilmore W, Peterson S.Corn from an Arkansas farm, where three horses died and others became sick, was investigated for causative principles. Necropsy of the three horses revealed what appeared to be severe hepatic necrosis. Histopathological examination indicated a pattern of hepatic lesions that was suggestive of aflatoxin contamination of the feed. Mycological examination of the corn by dilution plating revealed 95% of the colonies as Aspergillus flavus. Chemical analysis of the corn for mycotoxins was positive for aflatoxin B1, B2, and M1 at concentrations of 114, 10, and 6 micrograms/Kg, respectively. Cyclopiaz...
Feed additives and contaminants as a cause of equine disease.
The Veterinary clinics of North America. Equine practice    August 1, 1990   Volume 6, Issue 2 467-478 doi: 10.1016/s0749-0739(17)30552-7
Whitlock RH.The equine practitioner often encounters serious diagnostic and therapeutic challenges regarding the specific origin of a disease. Such challenges may occur when horses become unaccountably ill after consuming what was thought to be acceptable feed but which in fact was contaminated or contained additives intended for other species. Examples of such additives and contaminants are monensin, lasalocid, salinomycin, blister beetles, and such antimicrobics as lincomycin and clindamycin.

Application of high-performance liquid chromatography–inductively coupled plasma mass spectrometry to the investigation of cadmium speciation in pig kidney following cooking and in vitro gastro-intestinal digestion.
The Analyst    August 1, 1989   Volume 114, Issue 8 895-899 doi: 10.1039/an9891400895
Crews HM, Dean JR, Ebdon L, Massey RC.The speciation of cadmium in retail pig kidney has been examined by size-exclusion chromatography (SEC) coupled directly to inductively coupled plasma mass spectrometry (ICP-MS). Approximately 35% of the cadmium from uncooked kidney was soluble after aqueous extraction at pH 8 and SEC - ICP-MS revealed three discrete peaks whose retention times corresponded to estimated relative molecular masses of 1.2 x 10(6), 7.0 x 10(4) and 6 x 10(3)-9 x 10(3). In the cooked kidney, 35% of the Cd was soluble and was all associated with a peak of a relative molecular mass (Mr) of 6 x 10(3)-9 x 10(3). After s...
Tremorgenic syndromes in livestock.
The Veterinary clinics of North America. Food animal practice    July 1, 1989   Volume 5, Issue 2 291-300 doi: 10.1016/s0749-0720(15)30977-4
Nicholson SS.Grasses that are essential components of livestock grazing programs sometimes are the source of tremorgenic toxicants to the animals consuming them. Morbidity can be high but mortality need not be if management closely observes the cattle daily and removes them at first sign of trouble. Specific treatment generally is not available nor needed. Survivors recover completely within a few days or weeks, except in chronic phalaris poisoning, where sheep and cattle may die after prolonged illness--or at least not make an economical recovery. Certain poisonous plants are responsible for tremorgenic s...
Toxicity of field samples and Fusarium moniliforme from feed associated with equine-leucoencephalomalacia.
Archives of environmental contamination and toxicology    May 1, 1989   Volume 18, Issue 3 439-442 doi: 10.1007/BF01062371
Vesonder R, Haliburton J, Golinski P.Feed samples of corn, pelleted feed, and oats associated with equine leucoencephalomalacia (ELEM) were obtained from North Carolina, Illinois, Indiana, and Oklahoma. These samples contained a high colony density of Fusarium moniliforme Sheldon which ranged from 64 to 87% of the total fungi. Fifty-nine F. moniliforme strains were isolated. Isolates of F. moniliforme in feed samples from Illinois, Indiana, and Oklahoma were cultured on corn. The fermented corn, mixed with regular feed and fed to one-day-old ducklings, effected a high mortality coefficient (average 55%). Methanol extracts of corn...
[Sublimation-dried mare’s milk and the possibility of its use in creating infant and dietary food products].
Voprosy pitaniia    March 1, 1988   Issue 2 64-67 
Stoianova LG, Abramova LA, Ladodo KS.The main biological parameters were studied in sublimated mare's milk: protein fraction composition, amino-acid spectrum, fatty-acid composition of lipids and the content of vitamins and mineral substances. A high biological value of the sublimated mare's milk has been proved, as well as significant proximity of its composition to human milk. Preliminary data have evidenced expediency of mare's milk use for the development of adapted milk mixtures for baby foods. However, the fatty component of the mixtures needs certain correction by addition of vegetable oil. The sublimated mare's milk can b...
Persistence of encysted Toxoplasma gondii in tissues of equids fed oocysts.
American journal of veterinary research    August 1, 1985   Volume 46, Issue 8 1753-1754 
Dubey JP.Thirteen 6-month- to 13-year-old equids were each inoculated orally with 10,000 infective Toxoplasma gondii oocysts. The equids remained clinically normal. Equids were euthanatized on postinoculation days 33, 45, 90, 104, 120, 140, 162, 183, 197, 204, 211, 294, and 476. Their tissues were bioassayed for viable oocysts by feeding muscles to Toxoplasma-free cats and by inoculation of pepsin digests of 13 organs into mice. Using mouse inoculation, T gondii was recovered from tissues of the 9 equids euthanatized on each of postinoculation days 33, 45, 120, 140, 183, 197, 211, 294, and 476. Toxopla...
The prevalence of Toxoplasma gondii antibodies in man in Plateau State and meat animals in Nigeria.
Transactions of the Royal Society of Tropical Medicine and Hygiene    January 1, 1985   Volume 79, Issue 1 21-23 doi: 10.1016/0035-9203(85)90223-8
Osiyemi TI, Synge EM, Agbonlahor DE, Agbavwe R.Toxoplasma gondii antibodies were found in the sera of 22.86% of people in the Jos area of Plateau State, Nigeria. The incidence of antibodies in Nigerian food animals was 17.40%, the highest being in sheep (21.92%) and lowest in goats (13.88%). Cattle and horses were roughly equally infected--about 17.0%. The zoonotic potential of T. gondii in food animals is stressed and epidemiological factors are reviewed.

Outbreak of botulism in horses.
Equine veterinary journal    November 1, 1984   Volume 16, Issue 6 519-521 doi: 10.1111/j.2042-3306.1984.tb02005.x
Kelly AP, Jones RT, Gillick JC, Sims LD.An outbreak of nervous disease in Standardbred horses occurred near Bendigo, in south-eastern Australia, in October 1980. Over a two week period 11 horses in four training stables were affected with gait abnormalities, depression and recumbency. Eight of the 11 died. The results of an investigation implicated Clostridium botulinum toxin as the cause. The toxin was food-borne as a contaminant of oaten chaff.
Identification of swainsonine as a probable contributory mycotoxin in moldy forage mycotoxicoses.
Applied and environmental microbiology    August 1, 1984   Volume 48, Issue 2 386-388 doi: 10.1128/aem.48.2.386-388.1984
Broquist HP, Mason PS, Hagler WM, Harris TM.When infested with the fungus Rhizoctonia leguminicola, certain forages, e.g., red clover hay, can cause a "slobber syndrome" of varying severity when consumed by ruminants. The causative agent has been presumed to be slaframine [(1S,6S,8aS)-1-acetoxy-6-aminooctahydroindolizine], which is produced by R. leguminicola. In one serious outbreak of the slobber syndrome in horses, the red clover forage involved was carefully examined and found to contain R. leguminicola and slaframine. An identical hay sample is shown here by ion-exchange chromatographic and gas chromatographic-mass spectrometric an...
The toxicity of Datura stramonium (thorn apple) to horses.
New Zealand veterinary journal    January 1, 1984   Volume 32, Issue 20 47 doi: 10.1080/00480169.1984.11728696
Williams S, Scott P.Meal contaminated by Datura stramonium seeds at the rate of 0.5% by weight was fed to two horses. Both horses showed clinical signs of depression, anorexia, weight loss, rapi heart and respiration rates, mydriasis, polyuria, polydipsia and diarrhoea. Both recovered with treatment. Maize screenings contaminated by the seeds had been used in the manufacture of the meal.
Cadmium and selenium levels in kidneys from Danish horses.
Nordisk veterinaermedicin    January 1, 1984   Volume 36, Issue 1-2 49-56 
Teilmann AM, Hansen JC.The content of cadmium and selenium in horse kidneys from Jutland , Denmark, in relation to age, local geographical variation and possible relationship between the two elements has been investigated. During the winter of 1982-1983 kidneys from 50 horses were sampled and analysed for cadmium and selenium. The cadmium content of the horse kidneys was recorded in connection with the age of the horses. The cadmium level increases until the animal has reached approximately 7 years of age. At this age the cadmium concentration levels off. A significant regional difference was shown. The cadmium cont...

[Physicochemical fat indices and the fatty acid composition of the lipids in mare’s milk and shubath (sour camel’s milk)].
Voprosy pitaniia    March 1, 1982   Issue 2 59-61 
Orlov VK, Servetnik-Chalaia GK.Physicochemical properties of fat and fatty-acid composition of mare's milk and shubath (sour milk product obtained from camel's milk) depend on the season. During summer these products show a higher content of fat and increased level of polyunsaturated fatty acids, particularly in mare's milk lipids. It has been shown that in mare's milk lipids 90% is due to acids with a carbon chain of C14-18, while shubath lipids contain almost 96% of such acids.
Renal cadmium and zinc concentrations in horses in Norway.
Nordisk veterinaermedicin    December 1, 1981   Volume 33, Issue 12 530-534 
Bjorland J, Norheim G.Much of the recent interest in cadmium has been inspired by concern about the increasing levels of this element in the environment. Exposure to low levels of cadmium may cause chronic effects. The intake of cadmium takes place mostly via foods. Therefore it is of interest to determine the cadmium levels in domestic animals in order to evaluate possible hazards both to animals and man.
[Nature of the vitamin composition of mare’s milk and koumiss depending on the time of year].
Voprosy pitaniia    July 1, 1981   Issue 4 46-48 
Servetnik-Chalaia GK, Mal'tseva LM.It was shown that the content of vitamins E, C, thiamine, riboflavin and niacin in mare's milk and kumyss varies depending on the season. The highest level of vitamins E, C and niacin was noted in May-June. The technological processing of mare's milk leads to the decreased content of vitamin C and niacin. Mare's milk and kumyss were found to contain dehydroascorbic acid in a considerable amount, especially in summer.
Carcinogenicity of dichlorvos.
Clinical toxicology    January 1, 1981   Volume 18, Issue 1 47-84 doi: 10.3109/15563658108990013
Reuber MD.Dichlorvos, 2,2-dichlorovinyl dimethyl phosphate, an organophosphate insecticide, is widely used for the control of agricultural, industrial, and domestic pests (Fig. 1) [1]. Dichlorvos is administered orally as an anthelmintic to swine, horses, cats, and dogs. It is applied by dermal application to cattle, goats, sheep, swine, and chickens to control fleas, flies, and mites. Cucumbers, radishes, lettuce, and tomatoes are treated with dichlorvos in greenhouses. Aerosols and strips are used for the control of ants, bedbugs, ticks, cockroaches, flies, mosquitoes, silverfish, spiders, and wasps. ...

[Findings on an epidemic of human trichinelliasis verified in Italy].
Parassitologia    January 1, 1980   Volume 22, Issue 1-2 107-134 
Mantovani A, Filippini I, Bergomi S.The present article completes the information already given in previous papers (Mantovani et al., 1976; Bellani et al., 1977; Mantovani, 1978) and is connected with the research on the infection of horses by Pampiglione et al. (1978). In September 1975 an epidemic of Trichinellosis involving at least 89 people was reported at Bagnolo in Piano (Reggio Emilia). This present article describes the epidemiological investigations. In the introductory part, the Trichinellosis outbreaks are summarized which were reported in Italy during this century along with research on domestic and wild animals. Th...
[Experimental infection of horses with Trichina larvae].
Parassitologia    December 1, 1978   Volume 20, Issue 1-3 183-192 
Pampiglione S, Baldelli R, Corsini C, Mari S, Mantovani A.The occurrence of a trichinellosis epidemic in the province of Reggio Emilia in 1975, the source of which was attributed to horse meat, led the authors to use this animal for experimental infections. By using the trichina strain isolated from the above outbreak, 4 horses were infected orally. All 4 animals became infected. The most affected muscles were the lingual, masticatory and neck ones. Meat from the 4 horses was subsequently fed to laboratory animals (rats, mice, guineapigs) and other domestic species (cats, dogs, pigs) and further infections were obtained. An attempt to infect also a s...

Further characterization of Listeria monocytogenes serotype 5.
Canadian journal of microbiology    May 1, 1978   Volume 24, Issue 5 598-599 doi: 10.1139/m78-097
Cooper RF, Dennis SM.Fifteen strains of Listeria monocytogenes serotype 5 were characteriized for carbohydrate utilization, enzymic reactions, and other differential criteria. Hemolytic patterns were tested on ovine, bovine, equine, human and lapine blood agars. Results were compared with those of previously reported strains of L. monocytogens serotype 5.
Regulatory veterinary medicine in a changing environment.
Australian veterinary journal    May 1, 1977   Volume 53, Issue 5 236-240 doi: 10.1111/j.1751-0813.1977.tb00196.x
Mulhern FJ.There is an increasing need for the veterinary profession to meet the new challenges brought about by increased and intensified livestock production. These challenges consist of control and eradication of diseases, the humane treatment of animals and the prevention of transmission of disease from animals or animal products to man. Examples are given of the contribution which regulatory medicine activities have made to the prevention/control/eradication of screw worm, foot-and-mouth disease, Venezuelan equine encephalomyelitis, Newcastle disease, bovine brucellosis, hog cholera, and certain oth...

The problem of testing horse kidneys for the presence of antibiotics at meat inspection: how to avoid a false positive reaction.
Nordisk veterinaermedicin    July 1, 1976   Volume 28, Issue 7-8 377-380 
Korkeala H, Stabel-Taucher R, Pekkanen TJ.When 33 horse kidneys were tested for the presence of inhibitory substances by the Bacillus subtilis BGA method at pH 8 and the Micrococcus luteus ATCC 9341 method, 24 were positive and 9 negative. The pH of the seeded M. luteus test medium changed from pH 6.6 before incubation to 8.7 after 24 hours incubation at 30 degrees C. When the same 33 kidneys were tested by the B. subtilis BGA method, medium pH 6, and 15 of them also by the M. luteus method using a medium buffered to pH 6, all were negative. The cadmium concentration of the 33 horse kidneys was found to be 70.17 +/- 81.28 mg/kg wet we...
