“…Meteorological data were collected from an international weather database ( http://www.wunderground.com ), which had been widely used in previous studies 34 . The averaged data from available weather stations in Chengdu were used, where the retrieved data included daily average temperature (T: ℃), dew point temperature (DT: ℃), relative humidity (RH: %), wind speed (W: mph) and atmospheric pressure (P: Hg).…”

Chronic obstructive pulmonary disease (COPD) is the fourth major cause of mortality and morbidity worldwide and is projected to be the third by 2030. However, there is little evidence available on the associations of COPD hospitalizations with meteorological factors and air pollutants in developing countries/regions of Asia. In particular, no study has been done in western areas of China considering the nonlinear and lagged effects simultaneously. This study aims to evaluate the nonlinear and lagged associations of COPD hospitalizations with meteorological factors and air pollutants using time-series analysis. The modified associations by sex and age were also investigated. The distributed lag nonlinear model was used to establish the association of daily COPD hospitalizations of all 441 public hospitals in Chengdu, China from Jan/2015–Dec/2017 with the ambient meteorological factors and air pollutants. Model parameters were optimized based on quasi Akaike Information Criterion and model diagnostics was conducted by inspecting the deviance residuals. Subgroup analysis by sex and age was also performed. Temperature, relative humidity, wind and Carbon Monoxide (CO) have statistically significant and consistent associations with COPD hospitalizations. The cumulative relative risk (RR) was lowest at a temperature of 19℃ (relative humidity of 67%). Both extremely high and low temperature (and relative humidity) increase the cumulative RR. An increase of wind speed above 4 mph (an increase of CO above 1.44 mg/m3) significantly decreases (increases) the cumulative RR. Female populations were more sensitive to low temperature and high CO level; elderly (74+) populations are more sensitive to high relative humidity; younger populations (< = 74) are more susceptible to CO higher than 1.44 mg/m3. Therefore, people with COPD should avoid exposure to adverse environmental conditions of extreme temperatures and relative humidity, low wind speed and high CO level, especially for female and elderly patients who were more sensitive to extreme temperatures and relative humidity.

“…Post-thermal processing and the related unit operations associated with it remain a crucial challenge where the reintroduction of spoilage microorganisms and pathogenic microorganisms occurs. Among these are spoilage microorganisms, which includes Geobacillus stearothermphilus, Micrococcus, Bacillus cereus, Anoxybacillus flavithermus, Pseudomonas fluorescens, Enterobacter faecium and E. faecalis, and occasionally pathogenic microorganisms such as Salmonella and Listeria monocytogenes [55,[63][64][65][66]. These microbial hazards are currently controlled through the design of the equipment, environmental hygiene and routine testing [49,67].…”

“…Another relevant effect of climate change is on the dairy farm and food processing environment itself, which might be affected by extreme weather conditions such as drought and flooding due to precipitation, as reported for some dairy farms [117][118][119]. The temperature conditions at the distribution locations have been found to significantly influence the shelf-life and spoilage risk of dairy products, such as evaporated milk, by enabling the growth of spore forming bacteria [64].…”

“…As such, with the projected climate change effects, the optimum conditions during the distribution until retailing might be harder to maintain. Climate conditions and temperature during the distribution, retailing and consumption of the shelf-life of dairy products were shown to impact the microbial food safety of evaporated milk and pasteurized milk [64,150]. This is true for the presented dairy products, where most of the current storage conditions require a low temperature during storage.…”

Climate change is expected to affect many different sectors across the food supply chain. The current review paper presents an overview of the effects of climate change on the microbial safety of the dairy supply chain and suggest potential mitigation strategies to limit the impact. Raw milk, the common raw material of dairy products, is vulnerable to climate change, influenced by changes in average temperature and amount of precipitation. This would induce changes in the microbial profile and heat stress in lactating cows, increasing susceptibility to microbial infection and higher levels of microbial contamination. Moreover, climate change affects the entire dairy supply chain and necessitates adaptation of all the current food safety management programs. In particular, the review of current prerequisite programs might be needed as well as revisiting the current microbial specifications of the receiving dairy products and the introduction of new pretreatments with stringent processing regimes. The effects on microbial changes during distribution and consumer handling also would need to be quantified through the use of predictive models. The development of Quantitative Microbial Risk Assessment (QMRA) models, considering the whole farm-to-fork chain to evaluate risk mitigation strategies, will be a key step to prioritize actions towards a climate change-resilient dairy industry.
