Significant Public Health

Clostridium perfringens presents a significant public health hazard to consumers of foods which have undergone improper processing or have been improperly handled at some point before consumption. Factors involved in outbreaks of C. perfringens foodborne illness include contamination of food with either spores or vegetative cells of enterotoxigenic strains of C. perfringens, suitable growth temperature. pH, media, oxidation reduction potential, and adequate incubation time. With proper handling of food items, the risk of C. perfringens foodborne illness outbreaks can be eliminated.

Different Types

Chicken meat are being widely consumed as they contain high protein and a healthier unsaturated fat type. Chicken burger represent a consumer palatable chicken product. Both chicken and its products are liable to different types of contamination during their preparation and processing. Contamination by S. aureus and its enterotoxins poses a major public health hazard to chicken meat consumes. During this study 100 different samples of chicken fillet, deboned thigh, wing, mechanically deboned meat (MDM) and chicken burger (20 each) was collected from market and investigated for their S. aureus count and ability of the isolated strains to produce enterotoxins using conventional plating and isolation technique as well as using SET-RPLA toxin detection kit. Results revealed that mean values of S. aureus count in all samples exceeded the permissible limits and hence being unacceptable. MDM isolated exhibited staphylococcal enterotoxins (SEs) production of three different types SEA, SEC and SED. Meanwhile chicken burger S. aureus isolates produced only SEA and SEC enterotoxins. While isolated S. aureus from chicken fillet and deboned thigh didn’t exhibit any enterotoxin production activity. It’s recommended to follow the hygienic practices during different processing stages to avoid the risk of S. aureus and its enterotoxins.

Definition Of

Water, sanitation and hygiene (WASH) factors are responsible for 11.4% of deaths in Zambia, making WASH a key public health concern. Despite annual waterborne disease outbreaks in the nation’s peri-urban (slum) settlements being linked to poor WASH, few studies have proactively analysed and conceptualised peri-urban WASH and its maintaining factors. Our study aimed to (a) establish residents’ definition of peri-urban WASH and their WASH priorities; and (b) use ecological theory to analyse the peri-urban WASH ecosystem, highlighting maintaining factors. Our study incorporated 16 young people (aged 17–24) residing in peri-urban Lusaka, Zambia in a photovoice exercise. Participants took photographs answering the framing question, ‘What is WASH in your community?’ Then, through contextualisation and basic codifying, participants told the stories of their photographs and made posters to summarise problems and WASH priorities. Participant contextualisation and codifying further underwent theoretical thematic analysis to pinpoint causal factors alongside key players, dissecting the peri-urban WASH ecosystem via the five-tier ecological theory ranging from intrapersonal to public policy levels. Via ecological theory, peri-urban WASH was defined as: (a) poor practice (intrapersonal, interpersonal); (b) a health hazard (community norm); (c) substandard and unregulated (public policy, organisational); and (d) offering hope for change (intrapersonal, interpersonal). Linked to these themes, participant findings revealed a community level gap, with public policy level standards, regulations and implementation having minimal impact on overall peri-urban WASH and public health due to shallow community engagement and poor acknowledgement of the WASH realities of high-density locations. Rather than a top-down approach, participants recommended increased government–resident collaboration, offering residents more ownership and empowerment for intervention, implementation and defending of preferred peri-urban WASH standards.

The Mean

Staphylococcus aureus, Clostridium perfringens. Salmonella choleraesuis, and Salmonella typhimurium were inoculated (108 cells or spores) into two slow cookers containing green bean casserole, baked navy beans, chicken cacciatore, barbecued ribs or pork pot roast, and their fate determined after cooking. Heating patterns also were determined at three positions inside the two cookers. None of the foods cooked in either of the slow cookers contained detectable levels of S. aureus or salmonellae. The similarity between C. perfringens vegetative and spore counts indicate that only spores were present in the cooked foods. Except for the green bean casserole cooked using a low temperature setting, cooking resulted in a 0.44–1.67 and 0.36–1.54 log count reduction, respectively, of vegetative cells and spores of C. perfringens. Counts of vegetative cells and spores after cooking the green bean casserole were approximately .18 and .30 log counts higher than the uncooked counts. The mean times for the coldest areas in Cooker A to reach 50 C were 2.57 and 0.97 h, respectively, for the low (80 watts) and high (160 watts) temperature settings. The mean times for the coldest areas in Cooker B (removable liner) to reach 50 C were 2.35 and 0.52 h for the low (130 watts) and high (260 watts) temperature settings, respectively. Results suggest that when the recommended quantities of ingredients are used and the proper cooking procedure followed, foods prepared in the slow cookers studied do not present a health hazard.

In the Newsletter of January 1, 1968, the American Academy of Pediatrics reported that the executive board strongly endorsed time American Cancer Society's anti-smoking resolution. Personally, I cannot agree with the approach of the resolution to the public health hazard of smoking. If the American Academy of Pediatrics (or for that matter, the American Cancer Society) wanted to back effective measures, an entirely different type of resolution would have been adopted, one that would have put the emphasis On reaciling the younger generation.
