Data on foodborne disease in Canada in 1976 were compared with data for 1975. A total of 858 incidents, comprising 752 outbreaks and 106 single cases, causing illness in 5367 persons were reported for 1976. The number of outbreaks increased by 5.9% over those for 1975, but the total number of cases decreased by 24.5%. As for previous years, Staphylococcus aureus was responsible for more incidents (27) than any other agent. Other incidents were caused by Salmonella spp. (25), Clostridium perfringens (19) suspect mold and yeast (17), Bacillus spp. (10), Clostridium botulinum (4) and suspect Pseudomonas aeruginosa (4). Seven incidents of trichinosis occurred. Chemicals implicated in causing illness included metals, rancid compounds, a pesticide and solvents. The deaths of five persons were attributed to foodborne disease. About 35% of incidents and 41% of cases were associated with meat and poultry. Bakery products, vegetables, fruits and Chinese food continued to play a prominent role in the spread of foodborne disease, as in previous years. Mishandling of food took place mainly in foodservice establishments (18.9% of incidents, 52.7% of cases) or homes (10.5% of incidents, 6.8% of cases). However, mishandling by the manufacturer caused some problems, including three separate incidents involving fermented sausages. More than 60% of reported foodborne disease incidents occurred in Ontario and the number of incidents per 100,000 population was highest in Ontario and British Columbia. Narrative reports of foodborne outbreaks are presented. Relatively few illnesses resulted from consumption of, or contact with, water; a total of 9 incidents and 1476 cases occurred from ingestion of water and a further three incidents were recorded as a result of penetration of the skin by swimmers' itch parasite (many hundreds of cases) and invasion of wounds in swimmers by Vibrio parahaemolyticus.

Data on foodborne disease in Canada in 1977 were compared with data for 1976. A total of 777 incidents, comprising 660 outbreaks and 117 single cases, causing illness in 4810 persons was reported for 1977. The number of incidents and cases decreased by 9.7% and 10.4%, respectively, from 1976 to 1977. Unlike previous years, Salmonella spp. were responsible for more incidents (32) and cases (763) than any other agent. Other incidents were caused by Staphylococcus aureus (23), Clostridium perfringens (14), suspect mold and yeast (13), Bacillus spp. (11), Clostridium botulinum (5), Shigella sonnei (1) and suspect Pseudomonas aeruginosa (1). Three incidents of trichinosis, and two each of mushroom and paralytic shellfish poisoning occurred. Chemicals implicated in causing illness included tin, rancid compounds and extraneous matter. The deaths of two persons were attributed to foodborne disease. About 32% of incidents and 48% of cases were associated with meat and poultry. Bakery products, vegetables, fruits and Chinese food continued to play a prominent role in the spread of foodborne disease, as in previous years. Mishandling of food took place mainly in foodservice establishments (31.0% of incidents, 60.2% of cases) and homes (15.1% of incidents, 9.2% of cases). However, mishandling by the manufacturer caused some problems, including salmonellosis from cakes made with cracked eggs and staphylococcal intoxication from cheese prepared from a contaminated starter culture. More than 61% of reported foodborne disease incidents occurred in Ontario and over 16% in British Columbia, but the number of incidents per 100,000 population was highest in Northwest Territories and the Yukon. Relatively few illnesses resulted from the ingestion of water and none through contact with water with a total of 9 incidents and 305 cases. Narrative reports of foodborne and waterborne incidents are presented.

Data on foodborne disease in Canada in 1975 were compared with data for 1974. A total of 838 incidents, comprising 710 outbreaks and 128 single cases, and involving 7106 ill persons, was recorded for 1975. The number of outbreaks increased by 89% and single cases by 129% over those reported for 1974. As in 1974, Staphylococcus aureus was responsible for more incidents (37) than any other agent. Other incidents were caused by Salmonella (25), Clostridium perfringens (12), Clostridium botulinum (6), suspect mold and yeast (13) and suspect Streptococcus sp. (8). In both years, non-microbiological agents, mainly chemical, accounted for less than a quarter of the incidents of known etiology. Two persons were reported to have died through foodborne disease. About 41% of incidents and 50% of cases were associated with meat and poultry. Vegetables, fruits, bakery products, sandwiches and Chinese food also played a prominent role. Mishandling of food took place mainly in foodservice establishments (25% of incidents) or homes (20%). More than 60% of reported foodborne disease incidents occurred in Ontario. The number of incidents per 100,000 population was highest in the Northwest Territories (10.6), Ontario (6.4) and British Columbia (4.7). Narrative reports of five foodborne outbreaks are presented.

Data on foodborne disease in Canada in 1978 are compared with data for 1977. A total of 836 incidents, comprising 642 outbreaks and 194 single cases, causing illness in 5960 persons was reported for 1978. The number of incidents and cases increased by 7.5% and 23.9%, respectively, from 1977 to 1978. Like the previous year, Salmonella spp. were responsible for more incidents (67) and cases (2171) than any other agent. Other incidents were caused by Staphylococcus aureus (31), suspect mold and yeast (17), Bacillus cereus (9), Clostridium perfringens (7), Clostridium botulinum (6), and Shigelli sonnet (1). Four incidents of trichinosis, and two each of mushroom, lupin alkaloid and paralytic shellfish poisoning occurred. One scombroid poisoning outbreak was reported. Chemicals implicated in causing illness included tin, rancid compounds and extraneous matter. The deaths of five persons were attributed to foodborne disease. About 32% of incidents and 39% of cases were associated with meat and poultry. Vegetables, fruits, bakery products and marine products were also important vehicles in causing foodborne disease. Mishandling of food took place mainly in foodservice establishments (25.6% of incidents, 56.1% of cases) and homes (12.4% of incidents, 6.4% of cases). However, mishandling by manufacturers caused some problems including salmonellosis from iced cakes made with cracked eggs and staphylococcal intoxication from ham, sausage, chicken and canned salmon. Over 54% of reported foodborne disease incidents occurred in Ontario and more than 18% in British Columbia, but the number of incidents per 100,000 population was highest in the Northwest Territories. Narrative reports of selected foodborne incidents are presented.

Упоредним микробиолошким испитивањем узоракахране за животиње на Salmonella spp. из 25g и 50g узорка, током 2014. године,утврђен је идентичан проценат задовољавајућих, односно незадовољавајућихузорака.Анализом Правилника о микробиолошким критеријумима у храни заживотиње („Службени гласник БиХ“ број 67/12), уочава се постојање већег бројанелогичности и недостатака, како у погледу категорија хране за животиње, такои у вези граничних вриједности, као и метода испитивања. Hису обухваћене свекатегорије хране за животиње нити је прописана минимална количина узорказа испитивање. Правилник о микробиолошким критеријумима у храни за жи-вотиње треба да обухвати све категорије хране за животиње и да узме у обзиртехнолошки процес производње за сваку категорију. Испитивање узорака наClostridium perfringens треба да буде обавезно за све категорије хране за живо-тиње, а и испитивање на токсин Clostridium perfringens и Clostridium botulinum услучају сумње на тровање животиња, и то на захтјев службеног ветеринара иливетеринарског инспектора. Испитивање узорака хране за животиње на коагу-лаза позитивне стафилококе и Staphylococcus aureus не треба да буде обавезно,осим код млијека, млијека у праху и млијечних замјеница намијењених исхранимладих животиња. Код свих осталих врста хране, у случајевима сумње на тро-вање животиња, на захтјев службеног ветеринара или ветеринарског инспекто-ра треба обавезно урадити испитивање на присуство ентеротоксина стафило-кока. Гранична вриједност за Salmonella spp. у храни за животиње треба да буде„одсуство у 25g“, односно маса тест узорка треба да износи 25g. У правилникукоји дефинише микробиолошке критеријуме у храни за животиње потребно једефинисати минималну количину узорка за испитивање, која треба да износиминимално један килограм односно оригинално паковање.

Four species of fish from Atlantic waters, Meronia americanus (perch), Cynoscion regalis (seatrout), Micropogon undulatis (croaker) and Pomatomus saltatrix (bluefish), were processed (gutted or filleted), packaged under carbon dioxide and refrigerated. Stability of the fish under the modified atmosphere preservation (MAP) system was compared to that of fish stored conventionally. Use of the MAP system resulted in a 45 to 55% increase in stability, primarily due to an extension in the lag phase of psychrotrophic organisms and to their reduced growth rate in the logarithmic phase. By the 10th day of storage, the conventionally packed fish always exhibited a 100-fold higher psychrotroph count than the CO2-packed fish. Levels of Vibrio parahaemolyticus were negligible in this MAP system and no Salmonella spp. or Staphylococcus aureus was detected, even at an abuse temperature (10°C) of storage. Positive evidence for preformed Clostridium botulinum toxin was lacking.

Data on foodborne disease in Canada in 1984 are compared with those for 1983. A total of 1,181 incidents, comprising 1,016 outbreaks and 165 single cases, caused illnesses in 9,953 persons in 1984. These figures are the highest on record with almost double the number of cases occurring in 1983. Salmonella, Staphylococcus aureus, Clostridium perfringens, and Bacillus cereus were responsible for most of the illnesses. The main Salmonella serovars involved were S. typhimurium, S. enteritidis, and S. heidelberg. There were no incidents of parasitic infections or paralytic shellfish poisonings similar to 1983. Fifty-five incidents (82 cases) of chemical origin were recorded; extraneous matter and rancid compounds were the most frequently implicated. There were two deaths, one from botulism and the other from salmonellosis. Most of the illnesses were associated with meat and poultry (30.6% of incidents and 29.9% of cases). Dairy foods, particularly cheese, bakery products, and marine foods were also major vehicles of foodborne disease. Mishandling of food took place mainly in foodservice establishments (38.8% of incidents), homes (20.6% of incidents), and food processings establishments (5.9% of incidents). Chemicals, such as extraneous material and rancid compounds, were the agents associated with 40.0% of incidents caused by processors' mishandling. On a population basis, incidents were greatest in Ontario, followed by those in Quebec, British Columbia, and Manitoba. Details of several foodborne disease incidents are presented. In addition, seven incidents of waterborne disease were documented in 1984, five more than in 1983. Campylobacter, Salmonella and Yersinia were identified as pathogens associated with drinking water.

Data on foodborne disease in Canada in 1979 are compared with data for 1978. A total of 825 incidents, comprising 650 outbreaks and 175 single cases, causing illness in 5503 persons was reported for 1979. The number of incidents and cases decreased by 1.3% and 7.7%, respectively, from 1978 to 1979. Like the previous year, Salmonella spp. were responsible for more incidents (62) and cases (1754) than any other agent. Other incidents were caused by Staphylococcus aureus (29), suspect mold and yeast (18), Bacillus cereus (16), Clostridium perfringens (11), Bacillus subtilis (1) and Hafnia alvei (1). No Clostridium botulinum cases were reported. Five incidents of trichinosis, three of paralytic shellfish poisoning, two involving insect infestation and one each of scombroid, lupin alkaloid and broom tea poisoning and an allergic reaction from beef adulterated with pork were reported. Chemicals implicated in causing illness included tin, rancid compounds, monosodium glutamate and extraneous matter. The deaths of three persons were attributed to salmonellosis and probable mushroom poisoning. About 33% of incidents and 38% of cases were associated with meat and poultry. Vegetables, fruits, bakery products and marine products were also important vehicles in causing foodborne disease. Mishandling of food took place mainly in foodservice establishments (38.9% of incidents, 59.3% of cases) and homes (13.3% of incidents, 7.0% of cases). However, mishandling by manufacturers caused some problems including salmonellosis from a cake and staphylococcal intoxication from canned fish and sausages. Over 53% of reported foodborne disease incidents occurred in Ontario and more than 18% in British Columbia, but the number of incidents per 100,000 population was highest in the Northwest Territories. Narrative reports of selected foodborne incidents are presented. Four waterborne disease outbreaks were reported in 1979 with a total of 73 cases. Lack of adequate water treatment led to the illnesses in at least three of the outbreaks.
